Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 20 days and not less than 15 days prior to the date of the proposed payment and not less than 15 days after the receipt by the Trustee of the notice of the proposed payment.

Section 206. Calculation Agent.

(a) As long as any Notes are outstanding, the Company shall maintain a calculation agent for calculating the Settlement Rate in respect of the Notes (the “Calculation Agent”).

(b) Form of Reverse of Note.

This Note is a duly authorized issue of securities of the Company (herein collectively called the “Notes”), issued under an Indenture, dated as of March 9, 2004, as supplemented by the Fifth Supplemental Indenture, dated as of December 14, 2004, and the Eighth Supplemental Indenture, dated as of September 29, 2006 (the “Indenture”, which term shall have the meaning assigned to it in such

instrument), and as further supplemented by the Ninth Supplemental Indenture dated as of December 18, 2006 (the “Ninth Supplemental Indenture”), among the Company, Radiomóvil Dipsa, S.A. de C.V., a sociedad anónima de capital variable organized and existing under the laws of Mexico (herein called the “Guarantor”, which term includes any successor Person under the Indenture) and The Bank of New York (as successor to JPMorgan Chase Bank, N.A.), as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture, as supplemented by the Ninth Supplemental Indenture, for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Guarantor, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof.

Additional notes on terms and conditions identical to those of this Note (except for issue date, issue price and the date from which interest shall accrue and, if applicable, first be paid) may be issued by the Company without the consent of the Holders of the Notes. The amount evidenced by such additional Notes shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the Notes.

Payment of principal, interest, Additional Amounts and any other amounts due in respect of the Notes shall be made, except as provided below, in Dollars, in amounts determined by the Calculation Agent by translating the corresponding Peso amounts into Dollars at the Settlement Rate on the Rate Calculation Date applicable to the relevant Interest Payment Date, Redemption Date, Stated Maturity or other Maturity or payment date for Defaulted Interest pursuant to Section 306 of the Base Indenture.

For the purposes of translating Peso amounts into Dollars:

“Rate Calculation Date” means the second Mexican FX Day immediately preceding an Interest Payment Date, Redemption Date, Stated Maturity or other Maturity or other payment date for Defaulted Interest pursuant to Section 306 of the Indenture, as applicable. Notwithstanding the preceding sentence, if the Rate Calculation Date is not a Business Day, then the Rate Calculation Date will be the immediately preceding Mexican FX Day (i.e., prior to such second Mexican FX Day) that is a Business Day.

an exchange rate, that bank will be replaced by the Company, for the purpose of determining the Alternative Rate, with another leading bank or financial institution. In the event that the Calculation Agent determines, in its sole and absolute discretion, that neither the FIX FX Rate nor the Alternative Rate can be ascertained on a Rate Calculation Date in accordance with the foregoing, the Company will determine the Settlement Rate (and method of determining the Settlement Rate) in respect of such date in its sole and absolute discretion, taking into consideration all available information that in good faith it deems relevant.

Holders of the Notes may elect to receive payment of principal, interest, Additional Amounts and any other amounts due in respect of the Notes in Pesos. Holders who wish to elect to receive a particular payment of principal, interest, Additional Amounts and any other amounts due in respect of the Notes in Pesos must notify the principal Paying Agent no later than the 8^th day preceding the applicable Interest Payment Date, Redemption Date, Stated Maturity or other Maturity or payment date for Defaulted Interest pursuant to Section 306 of the Indenture (but not earlier than the applicable Regular Record Date or Special Record Date).

In any case where any Interest Payment Date, Redemption Date, Stated Maturity or other Maturity of the Notes shall not be a Business Day, then payment of interest, principal or Additional Amounts need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date, Redemption Date, Stated Maturity or other Maturity, as the case may be; provided that interest will accrue on the principal of the Notes at the applicable interest rate from the original Interest Payment Date, Redemption Date, Stated Maturity or other Maturity, as the case may be, to (but excluding) that next Business Day.

If an Event of Default with respect to Notes shall occur and be continuing, the principal of all of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture, as supplemented by the Ninth Supplemental Indenture.

All payments of principal and interest in respect of the Notes shall be made after withholding or deduction for any present or future taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or on behalf of Mexico or any authority therein or thereof having power to tax (“Mexican Taxes”). In the event of any withholding or deduction for any Mexican Taxes, the Company shall pay such additional amounts (“Additional Amounts”) as will result in receipt by the Holders of Notes on the respective due dates of such amounts as would have been received by them had no such withholding or deduction (including for any Mexican Taxes payable in respect of Additional Amounts) been required, except that no such Additional Amounts shall be payable with respect to any payment on a Note to the extent:

(i) that any such taxes, duties, assessments or other governmental charges would not have been imposed but for (A) a connection between the Holder and Mexico other than the ownership or holding of such Note or the mere receipt of payments with respect to such Note or (B) failure by the Holder or any other Person to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection with Mexico of the Holder or any beneficial owner of such Note if compliance is required by law, regulation 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 we have given the Holders at least 30 days’ notice prior to the first payment date with respect to which such certification, identification or reporting requirement is required to the effect that Holders will be required to provide such information and identification;

(ii) of any such taxes, duties, assessments or other governmental charges with respect to a Note presented for payment more than 15 days after the date on which such 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 15-day period;

(iii) of estate, inheritance, gift or other similar taxes, assessments or other governmental charge imposed with respect to a Note;

(iv) any tax, duty, assessment or other governmental charge payable otherwise than by deduction or withholding from payments on any series of Notes;

(v) any payment on a Note to a Holder who 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 such payment would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of such Note; and

For purposes of the provisions described in Clause (i) above, the term “Holder” of any Note means the direct nominee of any beneficial owner of such Note, which holds such beneficial owner’s interest in such Note. Notwithstanding the foregoing, the limitations on the Company’s obligation to pay Additional Amounts set forth in Clause (i)(B) above shall not apply if (a) the provision of information, documentation or other evidence described in such Clause (i)(B) would be materially more onerous, in form, in procedure or in the substance of information disclosed, to a Holder or beneficial owner of a Note (taking into account any relevant differences between U.S. and Mexican law, regulation or administrative practice) than comparable information or other reporting requirements imposed under U.S. tax law (including the United States - Mexico Income Tax Treaty), regulations (including proposed regulations) and administrative practice or (b) Rule 3.25.15 is in effect, unless the provision of the information, documentation or other evidence described in such Clause (i)(B) is expressly required by statute, regulation, rule or administrative practice in order to apply Rule 3.25.15 and the Company cannot obtain such information, documentation or other evidence on its own through reasonable diligence and the Company otherwise would meet the requirements for application of Rule 3.25.15. In addition, such Clause (i)(B) shall not be construed to require that a non-Mexican pension or retirement fund or a non-Mexican financial institution or any other Person 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. [If the Note is a Global Note, then insert — Persons who hold a beneficial interest in the Global Note through S.D. Indeval S.A. de C.V., Institución para el Depósito de Valores (“Indeval”), may be required to certify as to their residency in accordance with procedures established by Indeval.]

The Company shall provide the Trustee with the xxxxxxxxxx or other relevant documentation, if any, (which may consist of certified copies of such documentation) satisfactory to the Trustee evidencing the payment of Mexican Taxes in respect of which the Company has paid any Additional Amounts. Copies of such documentation shall be made available to the Holders of the Notes or the Paying Agent, as applicable, upon request therefor.

The Company shall pay all stamp, issue, registration, documentary or other similar duties, if any, which may be imposed by Mexico or any governmental entity or political subdivision therein or thereof, or any taxing authority of or in any of the foregoing, with respect to the Indenture or the Ninth Supplemental Indenture or the issuance of the Notes.

All references herein, in the Indenture, the Ninth Supplemental Indenture, the Notes or the Guarantees to principal or interest or any other amount payable in respect of any Note shall be deemed to include all Additional Amounts, if any, payable in respect of such principal, interest or other amount payable, unless the context otherwise requires, and express mention of the payment of Additional Amounts in any provision hereof shall not be construed as excluding reference to Additional Amounts in those provisions hereof where such express mention is not made.

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 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 Company. However, by making such assignment, the Holder makes no representation or warranty that the Company shall be entitled to receive such claim for a refund or credit and incurs no other obligation with respect thereto.

All references in the Indenture, the Ninth Supplemental Indenture, the Notes and the Guarantees to the Stated Maturity of the principal in respect of any Note shall be deemed to mean and include the Redemption Date, and all such references to principal, interest or Additional Amounts shall be deemed to mean and include any amount payable in respect hereof pursuant to Section 1010 of the Indenture.

The Notes are subject to redemption, upon not less than 30 nor more than 60 days’ notice by mail, at any time as a whole but not in part, at the election of the Company, at a cash price equal to the sum of (A) the principal amount of the Notes being redeemed, (B) accrued and unpaid current interest thereon to but not including the date fixed for redemption, and (C) any Additional Amounts which would otherwise be payable up to but not including the date fixed for redemption, if, as a result of any amendment to, or change in, the laws (or any laws, 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, administration or application of such laws, rules, or regulations (including a holding by a court of competent jurisdiction), which amendment or change of such laws, rules, or regulations becomes effective after December 7, 2006, the Company would be obligated, after making reasonable endeavors to avoid such requirement, to pay Additional Amounts in excess of the Additional Amounts that the Company would be obligated to pay if payments made on the Notes were subject to withholding or deduction of Mexican Taxes at the rate of 4.9%.

The Indenture, as supplemented by the Ninth Supplemental Indenture, permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the Guarantor, on the one hand, and the rights of the Holders of the Notes, on the other hand, at any time by the Company, the Guarantor and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time Outstanding. The Indenture also contains provisions (i) permitting the Holders of a majority in principal amount of the Notes at the time Outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the Indenture, as supplemented by the Ninth Supplemental Indenture, and (ii) permitting the Holders of a majority in principal amount of the Notes at the time Outstanding, on behalf of the Holders of all Notes, to waive certain past defaults under the Indenture, as supplemented by the Ninth

Supplemental Indenture, and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

As provided in and subject to the provisions of the Indenture, as supplemented by the Ninth Supplemental Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or the Ninth Supplemental Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes, the Holders of not less than 25% in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Notes at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture or the Ninth Supplemental Indenture and no provision of this Note or of the Indenture or the Ninth Supplemental Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture, as supplemented by the Ninth Supplemental Indenture and subject to certain limitations therein set forth (including, without limitation, the restrictions on transfer under Sections 208 and 211 of the Ninth Supplemental Indenture), the transfer of this Note is registrable in the Security Register, upon surrender of this Note for registration of transfer at the office of the Trustee or agency of the Company in any place where the principal of and any interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company, the Guarantor and the Security Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, shall be issued to the designated transferee or transferees.

The Notes are issuable only in registered form without coupons in denominations of Ps. 1,000,000 and integral multiples of Ps. 100,000 in excess thereof. As provided in the Indenture, as supplemented by Ninth Supplemental Indenture, and subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Note for registration of transfer, the Company, the Guarantor, the Trustee and any agent of the Company, the Guarantor or of the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Guarantor, the Trustee nor any such agent shall be affected by notice to the contrary.

[If the Note is a Global Note, then insert — This Note is a Global Note and is subject to the provisions of the Indenture and the Ninth Supplemental Indenture relating to Global Notes, including the limitations in Section 211 of the Ninth Supplemental Indenture on transfers and exchanges of Global Notes.]

This Note, the Guarantees and the Indenture and the Ninth Supplemental Indenture shall be governed by, and construed in accordance with, the laws of the State of New York.

The Transfer Restrictions shall cease and terminate with respect to any particular Restricted Note upon receipt by the Company and the Guarantor of evidence satisfactory to them (which may include an opinion of independent counsel experienced in matters of U.S. federal securities law) that, as of the date of determination, such Restricted Note (a) has been transferred by the Holder thereof pursuant to Rule 144, (b) has been sold pursuant to an effective registration statement under the Securities Act, or (c) has been transferred (i) in a transaction satisfying all the requirements of Rule 903 or 904 (as applicable) of Regulation S or (ii) pursuant to Rule 144A, and receipt by the Trustee of an Officer’s Certificate certifying that the Company and the Guarantor have received such evidence which may include an opinion of counsel stating that the Transfer Restrictions have ceased and terminated with respect to such Note. All references in the preceding sentence to any regulation, rule or provision thereof shall be deemed also to refer to any successor provisions thereof. In addition, the Company and the Guarantor may terminate the Transfer Restrictions with respect to any particular Restricted Note in such other circumstances as they determine are appropriate for this purpose and shall deliver to the Trustee an opinion of counsel, if any, and Officer’s Certificate certifying that the Transfer Restrictions have ceased and terminated with respect to such Note.

At the request of the Holder and upon the surrender of such Restricted Notes, together with Guarantees of the Guarantor annexed thereto or endorsed thereon, to the Trustee or Security Registrar for exchange in accordance with the provisions of this Section 211, any Restricted Note as to which the Transfer Restrictions shall have terminated in accordance with the preceding paragraph shall be exchanged for a new Note of like aggregate principal amount, but without the Restrictive Legends. Any Restricted Note as to which the Restrictive Legends shall have been removed pursuant to this paragraph (and any Note issued upon registration of transfer of, exchange for or in lieu of such Restricted Note) shall thereupon cease to be a “Restricted Note” for all purposes of this Ninth Supplemental Indenture.

The Company shall notify the Trustee in writing of the effective date of any registration statement registering any Restricted Notes under the Securities Act and shall ensure that any opinion of counsel received by it in connection with the removal of any Restrictive Legend is also addressed to the Trustee. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith and without negligence on its part in accordance with such notice or any opinion of counsel.

As used in this Section 211(a), the term “transfer” encompasses any sale, pledge, transfer or other disposition of any Notes referred to herein.

If an Owner Transferor wishes at any time to transfer a beneficial interest in a Regulation S Global Note or an Unrestricted Global Note to an Owner Transferee who wishes to take delivery thereof in the form of a beneficial interest in a Restricted Global Note, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this Section 211(b)(iii).
