The Company will pay interest semiannually in arrears on each Interest Payment Date of each year commencing March 28, 2006. 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 September 28, 2005. 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 will 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.

The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA. 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 and the TIA for a statement of those terms.

“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.

“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.

Optional Redemption for Changes in Withholding Taxes. 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 or other instrumentality 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 date on which the Notes we are offering are issued (which, in the case of a merger, consolidation or other transaction permitted and described under Section 4.1 of the Indenture, shall be treated for this purpose as the date of such transaction), we have become obligated, or will become obligated, in each case after taking all reasonable measures to avoid this requirement, to pay additional amounts in excess of those attributable to a Mexican withholding tax rate of 10% with respect to the Notes, then, at our option, all, but not less than all, of the Notes may be redeemed at any time on giving not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the outstanding principal amount, plus accrued and unpaid interest and any additional amounts due thereon up to but not including the date of redemption; provided, however, that (1) no notice of redemption for tax reasons may be given earlier than 90 days prior to the earliest date on which we 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 will deliver to the Trustee:

• a certificate signed by one of the Company’s duly authorized representatives 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

• opinion of Mexican legal counsel (which may be the Company’s counsel) of recognized standing to the effect that the Company has or will 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, will be irrevocable.

The Company will give notice to DTC pursuant to Section 5.3 of any redemption the Company proposes to make at least 30 days (but not more than 60 days) before the redemption date.

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 will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which Notes are listed or, if the Notes are not then listed on a national securities exchange, on a pro rata basis, by lot or by any other method as the Trustee shall deem fair and appropriate (subject to the procedures of DTC). If a partial redemption is made with the proceeds of an Equity Offering, selection of the Notes or portions thereof for redemption will, subject to the preceding sentence,

be made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the procedures of DTC), unless the method is otherwise prohibited. No Notes of a principal amount of US$1,000 or less may be redeemed in part and Notes of a principal amount in excess of US$1,000 may be redeemed in part in multiples of US$1,000 only.

Notice of any redemption will be mailed by first-class mail, postage prepaid, at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address. If Notes are to be redeemed in part only, the notice of redemption will state the portion of the principal amount thereof to be redeemed. For so long as the Notes are listed on Euro MTF, the alternative market of the Luxembourg Stock Exchange, the Company will cause notices of redemption also to be published as provided under Section 11.2. A new Note in a principal amount equal to the unredeemed portion thereof (if any) will 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 will be made, as appropriate).

The Company will pay the redemption price for any Note together with accrued and unpaid interest thereon through the date of redemption.

11. 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. Legal Tender 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.

13. 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 Notes may declare all the Notes to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will 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.

14. Trustee Dealings with the Company

Subject to certain limitations set forth in the Indenture, 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.

15. No Recourse Against Others

An incorporator, director, officer, employee, stockholder or controlling person, as such, of the Company or any Subsidiary Guarantor shall not have any liability for any obligations of the Company under the Notes, the Indenture or any Note Guarantee or for any claim based on, in respect of or by reason of such obligations or their creation.
