The Company will pay the principal of this Note on December 15, 2020. 

The Company promises to pay interest on the principal amount of this Note on each Interest Payment Date, as set forth below, at the rate

on June 1 or December 1 immediately preceding the Interest Payment Date) on each Interest Payment Date, commencing June 15, 2011. 
 Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from December 20, 2010; provided that, if there is no existing
default in the payment of interest and this Note is authenticated between a Regular Record Date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such Interest Payment Date. Interest will be

 The Company shall pay interest on overdue principal and

Register at the close of business on June 1 and December 1 immediately preceding the Interest Payment Date), in each case, even if the Note is cancelled on registration of transfer or registration of exchange after such record date;
provided that, with respect to the payment of principal, the Company will not make payment to the Holder unless this Note is surrendered to a Paying Agent. 
 The Company will pay principal, premium, if any, and, as provided above, interest (and Additional Amounts, if any) in money of the United States that at the time of payment is legal tender for
payment of public and private debts. However, the Company may pay principal, premium, if any, and interest by its check payable in such money. It may mail an interest check to a Holder’s registered address (as reflected in the Note Register).
If a payment date is a date other than a Business Day at a place of payment, payment may be made at that place on the next succeeding day that is a Business Day and no interest shall accrue for the intervening period.

	4.	Indenture; Limitations. 


The Company issued the Notes under an Indenture dated as of December 20, 2010 (the “Indenture”), between the Company and
the U.S. Bank National Association, as trustee (the “Trustee”) and as paying agent (“Paying Agent”). Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms.
To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control. 







 The Notes are general unsecured obligations of the Company. The Indenture limits the
aggregate principal amount of the Notes to U.S.$185,000,000 plus any Add On Notes or Exchange Notes that may be issued in exchange for Notes pursuant to the Registration Rights Agreement.

mail to each Holders’ last address as it appears in the Note Register, at the following Redemption Prices (expressed in percentages of principal amount), plus accrued and unpaid interest, liquidated damages, if any, and any Additional Amounts
(as defined in Section 4.20 of the Indenture) to the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date that is on or prior to the Redemption Date to receive interest due on an Interest Payment Date),
if redeemed during the 12-month period commencing December 15, of the years set forth below:

 In addition, at any time
prior to December 15, 2013, the Company may redeem up to 35.0% of the principal amount of the Notes with the Net Cash Proceeds of one or more Equity Offerings by the Company or KCS, to the extent the Net Cash Proceeds thereof are contributed to
the Company or used to purchase Capital Stock (other than Disqualified Stock) of the Company from the Company, at a Redemption Price equal to 106.625% of the principal amount thereof, plus accrued interest, liquidated damages, if any, and any
Additional Amounts to the Redemption Date; provided, however, that after giving effect to any such redemption: 
  

	 	(1)	at least 65.0% of the original aggregate principal amount of the Notes remains outstanding; and 


 

	 	(2)	any such redemption must be made within 90 days of such Equity Offering and must be made in accordance with certain procedures set forth in the Indenture.


 At any time prior to December 15, 2015, the Company may also redeem all or part of the Notes, upon not
less than 30 days nor more than 60 days’ prior notice by first-class mail to each Holder’s registered address, at a Redemption Price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and
unpaid interest if any, to the Redemption Date, subject to the rights of Holders of Notes on the relevant Record Date to receive interest due on the relevant Interest Payment Date.

amount up to 2.0% of the original aggregate principal amount of the Notes issued at a redemption price of 100.0% of their principal amount plus accrued interest, if any, and any Additional Amounts to the Redemption Date. 

 

	6.	Redemption for Changes in Withholding Taxes. 

 The Notes will be subject to redemption, in whole but not in part, at the option of the Company at any time at 100.0% of their principal amount together with accrued interest, liquidated damages, if any,
and any Additional Amounts thereon, if any, to the Redemption Date, in the event the Company has become or would become obligated to pay, on the next date on which any amount would be payable with respect to the Notes, any Additional Amounts in
excess of those attributable to a withholding tax rate of 4.9% as a result of a change in or amendment to the laws (including any regulations or general rules promulgated thereunder) of Mexico (or any political subdivision or taxing authority
thereof or therein), or any change in or amendment to any official position regarding the application, administration or interpretation of such laws, regulations or general rules, including a holding of a court of competent jurisdiction, which
change or amendment is announced or becomes effective on or after January 7, 2010. The Company shall not, however, have the right to redeem Notes from a Holder pursuant to this Section except to the extent that it is obligated to pay Additional
Amounts to such Holder that are greater than the Additional Amounts that would be payable based on a Mexican Withholding Tax rate of 4.9%. 








	7.	Partial Redemption. 


Except with respect to Notes to be redeemed pursuant to the fourth paragraph set forth under the heading “– Optional
Redemption” above, in the case of any partial redemption, selection of the Notes for redemption will be made by the Trustee in compliance with the requirements, as certified to it by the Company, of the principal national securities exchange,
if any, on which such Notes are listed or, if such Notes are not listed on a national securities exchange, by lot or by such other method as such Trustee in its sole discretion shall deem to be fair and appropriate; provided that no Note of
U.S.$2,000 in principal amount or less shall be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption relating to such Note shall state the portion of the principal amount thereof to be redeemed. A Note in principal
amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. 
  

	8.	Notice of Redemption. 


Notice of any redemption pursuant to Section 5 hereof will be mailed at least 30 days but not more than 60 days before the Redemption
Date to each Holder of Notes to be redeemed at his or her last address as it appears in the Note Register. Notice of any redemption pursuant to Section 6 hereof will be mailed at least six days before the Redemption Date to each Holder of Notes
to be redeemed at his or her last address as it appears in the Note Register. Notes in original denominations larger than U.S.$2,000 may be redeemed in part. On and after the Redemption Date, interest ceases to accrue and the principal amount shall
remain constant (using the principal amount as of the Redemption Date) on Notes or portions of Notes called for redemption, unless the Company defaults in the payment of the Redemption Price. 

 

	9.	Repurchase upon Change of Control. 

 Upon the occurrence of any Change of Control, each Holder shall have the right to require the repurchase of its Notes by the Company in cash pursuant to the offer described in the Indenture at a purchase
price equal to 101.0% of the principal amount thereof on the date of repurchase plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Payment”). 

A notice of such Change of Control will be mailed within 30 days after any Change of Control occurs to each Holder at his last address as
it appears in the Note Register. Notes in original denominations larger than U.S.$2,000 may be sold to the Company in part. On and after the Change of Control Payment Date, interest ceases to accrue on Notes or portions of Notes surrendered for
purchase by the Company, unless the Company defaults in the payment of the Change of Control Payment.

 The Notes are in registered form without coupons in minimum denominations of U.S.$2,000 of principal amount and multiples of U.S.$1,000 in excess thereof. A Holder may register the transfer or exchange of
Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar
need not register the transfer or exchange of any Notes selected for redemption. Also, it need not register the transfer or exchange of any Notes for a period of 15 days before a selection of Notes to be redeemed is made. 

 

	11.	Persons Deemed Owners. 

 A
Holder shall be treated as the owner of a Note for all purposes. 
  

	12.	Unclaimed Money. 

 If
money for the payment of principal, premium, if any, or interest remains unclaimed for two years, the Trustee and the Paying Agent will pay the money back to the Company at its request. After that, Holders entitled to the money must look to the
Company for payment, unless an abandoned property law designates another Person, and all liability of the Trustee and such Paying Agent with respect to such money shall cease. 








	13.	Discharge Prior to Redemption or Maturity. 

 The Company’s obligations pursuant to the Indenture will be discharged, except for obligations pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the
Notes or upon the irrevocable deposit with the Trustee of U.S. Dollars or Government Securities sufficient to pay when due principal of and interest on the Notes to maturity or redemption, as the case may be. 

 

	14.	Amendment; Supplement; Waiver. 

 Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding, and any
existing default or compliance with any provision may be waived with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding. Without notice to or the consent of any Holder, the parties thereto may amend
or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency and make any change that does not materially and adversely affect the rights of any Holder.

additional Indebtedness, make Restricted Payments, use the proceeds from Asset Sales, enter into sale-leaseback transactions, engage in transactions with Affiliates or, with respect to the Company, merge, consolidate or transfer substantially all of
their assets. Within 90 days after the end of each fiscal year, the Company must report to the Trustee on compliance with such limitations.
