Kansas City Southern de México, S.A. de C.V., a sociedad anónima de capital variable organized under the laws of the United Mexican States (the “Company”), proposes (i) to make an offer (the “2020 Notes Exchange Offer”) to exchange up to $275,000,000 aggregate principal amount of its 2.35% Senior Notes due 2020 (the “2020 Exchange Notes”) for an equal aggregate principal amount of its outstanding 2.35% Senior Notes due 2020 (the “2020 Old Notes”) and (ii) to make an offer (the “2023 Notes Exchange Offer” and, together with the 2020 Notes Exchange Offer, the “Exchange Offers”) to exchange up to $450,000,000 aggregate principal amount of its 3.00% Senior Notes due 2023 (the “2023 Exchange Notes” and, together with the 2020 Exchange Notes, the “Exchange Notes”) for an equal aggregate principal amount of its outstanding 3.00% Senior Notes due 2023 (the “2023 Old Notes” and, together with the 2020 Old Notes, the “Old Notes”). The terms and conditions of the Exchange Offers as currently contemplated are set forth in a prospectus (the “Prospectus”) included in the Company’s registration statement on Form S-4 (the “Registration Statement”) to be filed with the Securities and Exchange Commission (the “SEC”) on August     , 2013. The Old Notes and the Exchange Notes are collectively referred to in this Exchange Agent Agreement (this “Agreement”) as the “Notes” or the “Securities.” Capitalized terms used herein and not defined shall have the respective meanings ascribed to them in the Registration Statement or the accompanying letter of transmittal (the “Letter of Transmittal”).

The Company hereby appoints U.S. Bank National Association to act as exchange agent (the “Exchange Agent”) in connection with the Exchange Offers. References hereinafter to “you” shall refer to U.S. Bank National Association.

The Company shall give the Exchange Agent reasonable prior notice of the commencement date of the Exchange Offers. The Letter of Transmittal accompanying the Registration Statement is to be used by the holders of the Old Notes to tender into the applicable Exchange Offer, and contains instructions with respect to the delivery of Old Notes tendered. The Exchange Agent’s obligations with respect to the receipt and inspection of each Letter of Transmittal in connection with the Exchange Offers shall be satisfied for all purposes hereof by (1) inspection of the electronic message transmitted to the Exchange Agent by participants in the Exchange Offers in accordance with the Automated Tender Offer Program (“ATOP”) of The Depository Trust Company (“DTC”), and by otherwise observing and complying with all procedures established by DTC in connection with ATOP, to the extent that ATOP is utilized by such participants, or (2) inspection of the Letter of Transmittal submitted by each holder of Old Notes who does not use ATOP and submits a physical Letter of Transmittal to the Exchange Agent.

The Exchange Offers shall expire at 5:00 p.m., New York City time on such date as the Company shall notify the Exchange Agent prior to commencement of the Exchange Offers, or such later date or time to which the Company may extend the Exchange Offers (the “Expiration Date”). Subject to the terms and conditions set forth in the Registration Statement, the Company expressly reserves the right to extend the Exchange Offers from time to time and may extend the Exchange Offers by giving oral (confirmed in writing) or written notice to you, and by giving holders of Notes notice by press release, at any time before 5:00 p.m., New York City time, on the business day immediately following the previously scheduled Expiration Date, and in such case the term “Expiration Date” shall mean the time and date on which the Exchange Offers as so extended shall expire.

The Company expressly reserves the right, in its sole discretion, to delay, amend or terminate the Exchange Offers, and not to accept for exchange any Old Notes not theretofore accepted for exchange, upon the occurrence of any of the conditions of the Exchange Offers specified in the Registration Statement under the caption “The Exchange Offers—Expiration Date; Extensions; Amendments.” The Company will give to you as promptly as practicable oral or written notice of any delay, amendment, termination or non-acceptance.

In carrying out your duties as Exchange Agent, you are to act in accordance with the following instructions:

1. You will perform such duties and only such duties as are specifically set forth herein or in the section of the Registration Statement captioned “The Exchange Offers,” in the Letter of Transmittal accompanying the Registration Statement and such duties which are necessarily incidental thereto.

2. You will establish a book-entry account with respect to (i) the 2020 Old Notes and (ii) the 2023 Old Notes at DTC for purposes of the Exchange Offers within two business days after the effective date of the Registration Statement, and any financial institution that is a participant in DTC’s systems may make book-entry delivery of the Old Notes by causing DTC to transfer such Old Notes into your applicable book-entry account in accordance with DTC’s procedure for such transfer.

3. You are to examine each of the Letters of Transmittal (or confirmation of book-entry transfers into your account at DTC) and any other documents delivered or mailed to you by or for holders of the Old Notes to ascertain whether (i) the Letters of Transmittal and any such other documents are duly executed and properly completed in accordance with instructions set forth therein or that such book-entry confirmations are in due and proper form and contain the information required to be set forth therein, and (ii) the Old Notes have otherwise been properly tendered. In each case where the Letter of Transmittal or any other document has been improperly completed or executed or where book-entry confirmations are not in due and proper form or omit certain information or some other irregularity in connection with the acceptance of the applicable Exchange Offer exists, you will endeavor to inform the presenters of the need for fulfillment of all requirements and to take any other action reasonably available to you as may be necessary or advisable to cause such irregularity to be corrected.

4. Subject to Section 5 below, tenders of Old Notes may be made only as set forth in the Letter of Transmittal and Old Notes shall be considered properly tendered to you only when tendered in accordance with the procedures set forth therein.

5. With the approval of the Chief Financial Officer, Secretary or any Alternate Secretary, Treasurer or Vice President of the Company (such approval, if given orally, promptly to be confirmed in writing) or any other party designated by such officer in writing, you are authorized to waive any irregularities in connection with any tender of Old Notes pursuant to the Exchange Offers.

6. You shall promptly advise the Company with respect to any Old Notes delivered subsequent to the Expiration Date and accept its instructions with respect to disposition of such Old Notes.

7. You shall accept tenders:

(a) in cases where the Old Notes are registered in two or more names only if signed by all named holders;

(b) in cases where the signing person (as indicated on the Letter of Transmittal) is acting in a fiduciary or a representative capacity only when evidence reasonably satisfactory to you of his or her authority so to act is submitted; and

(c) from persons other than the holder of Old Notes provided that customary transfer requirements, including any payment of applicable transfer taxes, are fulfilled.

You shall accept partial tenders of Old Notes where so indicated and as permitted in the Letter of Transmittal and return any untendered Old Notes through the facilities of DTC to the holder (or such other person as may be designated in the Letter of Transmittal) as promptly as practicable after expiration or termination of the Exchange Offers.

8. Upon satisfaction or waiver of all of the conditions to the Exchange Offers, the Company will notify you (such notice if given orally, promptly to be confirmed in writing) of its acceptance, promptly after the Expiration Date, of all Old Notes properly tendered and you, on behalf of the Company, will cause the exchange of such Old Notes for the applicable Exchange Notes and cause such Old Notes to be cancelled. Delivery of Exchange Notes will be made on behalf of the Company by you, subject to due authorization, execution and delivery of such Exchange Notes by the Company, at the rate of $1,000 principal amount of Exchange Notes (subject to adjustment) for each $1,000 principal amount of the applicable Old Notes tendered, and, in the case of Old Notes tendered, promptly after notice (such notice if given orally, promptly to be confirmed in writing) of acceptance of said Old Notes by the Company; provided, however, that in all cases, Old Notes tendered pursuant to the Exchange Offers will be exchanged only after confirmation of book-entry transfer into your account at DTC, a properly completed and duly executed Letter of Transmittal (or facsimile thereof) or an Agent’s Message (as defined in the Registration Statement) with any required signature guarantees and any other required document. Unless otherwise instructed in writing by the Company, you shall issue Exchange Notes only in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof.

Notice of any decision by the Company not to accept any Old Notes tendered shall be given (such notices if given orally, promptly shall be confirmed in writing) by the Company to you.

11. If, pursuant to the Registration Statement, the Company does not accept for exchange all or part of the Old Notes tendered because of an invalid tender, the occurrence of certain other events set forth in the Registration Statement or otherwise, you shall as soon as practicable after the expiration or termination of the Exchange Offers return those unaccepted Old Notes by appropriate book-entry transfer, together with any related required documents and the Letters of Transmittal relating thereto that are in your possession, to the persons who effected such book-entry transfer.
