 Ladies and Gentlemen:

 Introductory. 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 (“Mexico”) (the “Company”), proposes to issue and sell to the several initial purchasers named in Schedule A hereto (the “Initial Purchasers”), acting
severally and not jointly, the respective amounts set forth in such Schedule A of $275,000,000 aggregate principal amount of the Company’s 2.350% Notes due 2020 (the “2020 Notes”) and $450,000,000 aggregate principal amount of
the Company’s 3.000% Notes due 2023 (the “2023 Notes” and, together with the 2020 Notes, the “Notes”). J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Morgan
Stanley & Co. LLC have agreed to act as representatives of the several Initial Purchasers (in such capacity, the “Representatives”) in connection with the offering and sale of the Notes. 

The 2020 Notes will be issued pursuant to an indenture, to be dated as of the Closing Date (as defined in Section 2 hereof) (the
“2020 Indenture”), between the Company and U.S. Bank National Association, as trustee (the “2020 Trustee”). The 2023 Notes will be issued pursuant to an indenture, to be dated as of the Closing Date (the “2023
Indenture” and, together with the 2020 Indenture, the “Indentures” and each, an “Indenture”), between the Company and U.S. Bank National Association, as trustee (the “2023 Trustee” and,
together with the 2020 Trustee, the “Trustee”). The Notes will be issued in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”). 







 The holders of the Notes will be entitled to the benefits of a registration rights
agreement, to be dated as of the Closing Date (the “Registration Rights Agreement”), among the Company and the Representatives, pursuant to which the Company will agree to file with the Securities and Exchange Commission (the
“Commission”), under the circumstances set forth therein, (i) a registration statement under the Securities Act of 1933, as amended, and the rules and regulations of the Commission promulgated thereunder (collectively, the
“Securities Act”) relating to two additional series of debt securities of the Company, one series with terms substantially identical to the 2020 Notes and one series with terms substantially identical to the 2023 Notes
(collectively, the “Exchange Notes”), to be offered in exchange for the applicable series of Notes (the “Exchange Offers”) and (ii) to the extent required by the Registration Rights Agreement, a shelf
registration statement pursuant to Rule 415 of the Securities Act relating to the resale by certain holders of the Notes, and in each case, to use its best efforts to cause such registration statements to be declared effective. 

The Company has prepared and delivered to each Initial Purchaser copies of a Preliminary Offering Memorandum, dated April 24, 2013
(the “Preliminary Offering Memorandum”), and has prepared and delivered to each Initial Purchaser copies of a Pricing Supplement, dated the date hereof (the “Pricing Supplement”) and attached as Exhibit B hereto,
describing the terms of the Notes, each for use by such Initial Purchaser in connection with its solicitation of offers to purchase the Notes. The Preliminary Offering Memorandum and the Pricing Supplement are herein referred to as the
“Pricing Disclosure Package.” Promptly after the time this purchase agreement (this “Agreement”) is executed by the parties hereto (the “Time of Execution”), the Company will prepare and deliver to
each Initial Purchaser a final offering memorandum dated the date hereof (the “Offering Memorandum”). 
 The
Company understands that the Initial Purchasers propose to make an offering of the Notes on the terms and in the manner set forth herein and in the Pricing Disclosure Package and agrees that the Initial Purchasers may resell, subject to the
conditions set forth herein, all or a portion of the Notes to purchasers (the “Subsequent Purchasers”) at any time after the Time of Execution. The Notes are to be offered and sold to or through the Initial Purchasers without being
registered with the Commission under the Securities Act, in reliance upon exemptions therefrom. Pursuant to the terms of the Notes and the Indentures, investors who acquire Notes shall be deemed to have agreed that Notes may only be resold or
otherwise transferred, after the date hereof, if such Notes are registered for sale under the Securities Act or if an exemption from the registration requirements of the Securities Act is available (including the exemptions afforded by Rule 144A
under the Securities Act (“Rule 144A”) or Regulation S under the Securities Act (“Regulation S”)). 
 All references in this Agreement to the Preliminary Offering Memorandum or the Offering Memorandum shall be deemed to mean and include any document that is filed with the Commission under the Securities
Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder (collectively, the “Exchange Act”), prior to 4:30 p.m. New York City time on the date hereof (the “Initial Sale
Time”), and is or is deemed

Preliminary Offering Memorandum or the Offering Memorandum shall be deemed to include the filing of any document under the Exchange Act after the Initial Sale Time and prior to the consummation of the offering of the Notes, which is or is deemed to
be incorporated by reference in the Preliminary Offering Memorandum or the Offering Memorandum, as the case may be.

any person acting on its or any of their behalf (other than the Initial Purchasers, as to whom the Company makes no representation or warranty) has engaged or will engage, in connection with the offering of the Notes, in any form of general
solicitation or general advertising within the meaning of Rule 502 under the Securities Act. With respect to those Notes sold in reliance upon Regulation S, (i) none of the Company, its Affiliates or any person acting on its or their behalf

or will contain an untrue statement of a material fact or omits or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided
that this representation shall not apply to statements in or omissions from the Pricing Disclosure Package, the Offering Memorandum or any amendment or supplement thereto made in reliance upon and in conformity with information furnished to the
Company in writing by any Initial Purchaser through the Representatives expressly for use in the Pricing Disclosure Package, the Offering Memorandum or amendment or supplement thereto, as the case may be, it being understood and agreed that the only
such information furnished by any Initial Purchaser through the Representatives consists of the information described as such in Section 8(b) hereof. The Pricing Disclosure Package contains, and the Offering Memorandum will contain, all the

offering of the Notes contemplated by this Agreement were conducted as a public offering pursuant to a registration statement filed under the Securities Act with the Commission, would constitute an “issuer free writing prospectus,” as
defined in Rule 433 under the Securities Act (collectively, “Company Additional Written Communication”) reviewed and consented to by the Representatives and listed on Annex I hereto. Each such Company Additional Written
Communication, when taken together with the Pricing Disclosure Package, did not as of the Initial Sale Time, and will not at the Closing Date, contain any untrue statement of a material fact or omit to state a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that this representation shall not apply to statements in or omissions from each such Company Additional Written Communication
made in reliance upon and in conformity with information furnished to the Company in writing by any Initial Purchaser through the Representatives expressly for use in any Company Additional Written Communication, it being understood and agreed that
the only such information furnished by any Initial Purchaser through the Representatives consists of the information described as such in Section 8(b) hereof.

 SECTION 3. Covenants of the Company. 

The Company covenants and agrees with each Initial Purchaser as follows: 

a) Preparation of Offering Memorandum; Initial Purchasers’ Review of Proposed Amendments and Supplements. As promptly as
practicable following the Time of Execution and in any event not later than the second business day following the date hereof, the Company will prepare and deliver to the Initial Purchasers the Offering Memorandum, which shall consist of the
Preliminary Offering Memorandum as modified only by the information contained in the Pricing Supplement and other immaterial changes as agreed to by the Representatives (or their counsel). The Company will not amend or supplement the Preliminary
Offering Memorandum, the Pricing Supplement or the Offering Memorandum prior to the Closing Date unless the Initial Purchasers shall previously have been furnished a copy of the proposed amendment or supplement at least one business day prior to the
proposed use or filing, and shall not have objected to such amendment or supplement. 
 b) Amendments and Supplements to the
Offering Memorandum and Other Securities Act Matters. If, prior to the later of (x) the Closing Date and (y) the completion of the placement of the Notes by the Initial Purchasers with the Subsequent Purchasers, in the reasonable
judgment of the Company or the Representatives, (i) any event shall occur or condition exist as a result of which the Pricing Disclosure Package or the Offering Memorandum, as applicable, as then amended or supplemented, would include any
untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the 

  
 12 









 
circumstances under which they were made, not misleading, or (ii) it is otherwise necessary to amend or supplement the Offering Memorandum to comply with applicable law, the Company agrees
to promptly prepare (subject to Section 3 hereof), file with the Commission and furnish at its own expense to the Initial Purchasers, amendments or supplements to the Pricing Disclosure Package or the Offering Memorandum, as applicable, so that
the statements in the Pricing Disclosure Package and the Offering Memorandum, as applicable, as so amended or supplemented will not, in the light of the circumstances under which they were made, be misleading or so that the Pricing Disclosure
Package or the Offering Memorandum, as applicable, as amended or supplemented, will comply with all applicable law. 
 c)
Copies of the Offering Memorandum. The Company agrees to furnish the Initial Purchasers, without charge, as many copies of the Pricing Disclosure Package and the Offering Memorandum and any amendments and supplements thereto as they shall
have reasonably requested. 
 d) Blue Sky Compliance. The Company shall cooperate with the Representatives and counsel
for the Initial Purchasers to qualify or register the Notes for sale under (or obtain exemptions from qualification or registration under) the state securities or blue sky laws of those jurisdictions designated by the Representatives, shall comply
with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Notes. The Company shall not be required to qualify to transact business or to take any action that would
subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign business. The Company will advise the Representatives promptly of the suspension of the
qualification or registration of (or any such exemption relating to) the Notes for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order
suspending such qualification, registration or exemption, the Company shall use its reasonable best efforts to obtain the withdrawal thereof at the earliest possible moment. 
 e) Use of Proceeds. The Company shall apply the net proceeds from the sale of the Notes sold by it in the manner described under the caption “Use of Proceeds” in the Pricing Disclosure
Package and the Offering Memorandum. 
 f) Depositary. The Company will cooperate with the Initial Purchasers and use its
best efforts to permit the Notes to be eligible for clearance and settlement through the facilities of the Depositary. 
 g)
Periodic Reporting Obligations. Prior to the completion of the placement of the Notes by the Initial Purchasers with the Subsequent Purchasers, the Company shall file, on a timely basis, with the Commission all reports and documents required
to be filed under Section 13 or 15 of the Exchange Act. Additionally, at any time when the Company is not subject to Section 13 or 15 of the Exchange Act, for the benefit of holders and beneficial owners from time to time of the Notes, the
Company shall furnish, at its expense, upon request, to holders and beneficial owners of Notes and prospective purchasers of Notes information satisfying the requirements of Rule 144A(d). 

  
 13 









 h) Agreement Not to Offer or Sell Additional Securities. During the period commencing
on the date hereof and ending on the Closing Date, the Company will not, without the prior written consent of the Representatives (which consent may be withheld at the sole discretion of the Representatives), directly or indirectly, sell, offer,
contract or grant any option to sell, pledge, transfer or establish an open “put equivalent position” within the meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or transfer, or announce the offering of, or file any
registration statement under the Securities Act in respect of, any debt securities of the Company similar to the Notes or securities exchangeable for or convertible into debt securities similar to the Notes (other than as contemplated by this
Agreement with respect to the Notes). 
 i) No Integration. The Company agrees that it will not and will cause its
Affiliates not to make any offer or sale of securities of the Company of any class if, as a result of the doctrine of “integration” referred to in Rule 502 under the Securities Act, such offer or sale would render invalid (for the purpose
of (i) the sale of the Notes by the Company to the Initial Purchasers, (ii) the resale of the Notes by the Initial Purchasers to Subsequent Purchasers or (iii) the resale of the Notes by such Subsequent Purchasers to others) the
exemption from the registration requirements of the Securities Act provided by Section 4(2) thereof or by Rule 144A or by Regulation S thereunder or otherwise. 
 j) No Restricted Resales. During the period of one year after the Closing Date, the Company will not, and will not permit any of its affiliates (as defined in Rule 144 under the Securities Act) to
resell any of the Notes which constitute “restricted securities” under Rule 144 that have been reacquired by any of them, except pursuant to an effective registration statement under the Securities Act. 

k) Regulation S Compliance. The Notes sold in reliance on Regulation S will be represented upon issuance by a temporary global
security that may not be exchanged for definitive securities until the expiration of the 40-day restricted period referred to in Rule 903 of the Securities Act and only upon certification of beneficial ownership of such Notes by non-U.S. persons or
U.S. persons who purchased such Notes in transactions that were exempt from the registration requirements of the Securities Act. 
 l) Legended Securities. Each certificate for a Note will bear the legend contained in “Transfer Restrictions” in the Pricing Disclosure Package and the Offering Memorandum for the time
period and upon the other terms stated in the Pricing Disclosure Package and the Offering Memorandum. 
 m) No Manipulation
of Price. The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, under the Exchange Act or otherwise, the stabilization or manipulation
of the price of any securities of the Company to facilitate the sale or resale of the Notes. 
 n) Listing. The Company
will use its reasonable best efforts to effect the admission to trading and listing of the Notes and the Exchange Notes on the Global Exchange Market of the Irish Stock Exchange and to maintain the trading and listing of the Notes and the Exchange


  
 14 









 
Notes on the Global Exchange Market of the Irish Stock Exchange for so long as such Notes and Exchange Notes are outstanding, and to have the Notes and the Exchange Notes admitted to trading on
the Global Exchange Market of the Irish Stock Exchange as promptly as practicable after the date hereof, and in any event prior to the date of the first interest payment on the Notes and Exchange Notes, as applicable. The Company agrees to supply to
the Irish Stock Exchange copies of the Preliminary Offering Memorandum and the Offering Memorandum and such other documents, information and undertakings as may be required for the purpose of obtaining and maintaining such listing. 

The Representatives, on behalf of the several Initial Purchasers, may, in their sole discretion, waive in writing the performance by the

 18 









 “THE SECURITY (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS ORIGINALLY ISSUED IN A
TRANSACTION EXEMPT FROM REGISTRATION UNDER SECTION 5 OF THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THE SECURITY EVIDENCED HEREBY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH
REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A
THEREUNDER. THE HOLDER OF THE SECURITY EVIDENCED HEREBY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) SUCH SECURITY MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1)(a) TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A
QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A UNDER THE SECURITIES ACT,
(b) OUTSIDE THE UNITED STATES TO A NON-U.S. PERSON IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 903 OR RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (c) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED
BY RULE 144 THEREUNDER (IF APPLICABLE), (d) TO AN INSTITUTIONAL ACCREDITED INVESTOR (AS DEFINED IN RULE 501(a)(1), (2), (3) OR (7) OF REGULATION D UNDER THE SECURITIES ACT) THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO THE TRUSTEE A
SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE REGISTRATION OF TRANSFER OF THIS NOTE AND, IF SUCH TRANSFER IS IN RESPECT OF AN AGGREGATE PRINCIPAL AMOUNT OF NOTES AT THE TIME OF TRANSFER OF LESS THAN US$250,000, AN
OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES ACT OR (e) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL


  
 19 









 
ACCEPTABLE TO THE COMPANY IF THE COMPANY SO REQUESTS), (2) TO THE COMPANY OR ITS AFFILIATES OR (3) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN EACH CASE, IN ACCORDANCE WITH
ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THE SECURITY EVIDENCED HEREBY OF THE RESALE
RESTRICTIONS SET FORTH IN CLAUSE (A) ABOVE. NO REPRESENTATION CAN BE MADE AS TO THE AVAILABILITY OF THE EXEMPTION PROVIDED BY RULE 144 FOR RESALE OF THE SECURITY EVIDENCED HEREBY.” 

(D) The Notes have not been and will not be registered with the Registro Nacional de Valores (National Registry of
Securities) maintained by the CNBV under the Securities and Exchange Law of Mexico (Ley del Mercado de Valores), and the Initial Purchasers have not offered or sold, and agree not to offer or sell, directly or indirectly, any Notes in Mexico
or for the account of any resident thereof, except pursuant to a private placement exemption set forth under Article 8 of the Securities and Exchange Law of Mexico and in compliance with applicable provisions of Mexican Law or in accordance with an
authorization to that effect. 
 Following the sale of the Notes by the Initial Purchasers to Subsequent
Purchasers pursuant to the terms hereof, the Initial Purchasers shall not be liable or responsible to the Company for any losses, damages or liabilities suffered or incurred by the Company, including any losses, damages or liabilities under the
Securities Act, arising from or relating to any resale or transfer of any Note by a Subsequent Purchaser. 

SECTION 8. Indemnification. 
 (a) Indemnification of the Initial Purchasers. The Company agrees to indemnify and hold harmless each Initial Purchaser, its directors, officers, employees, affiliates and each person, if any, who
controls any Initial Purchaser within the meaning of the Securities Act and the Exchange Act (collectively, the “Initial Purchaser Indemnified Parties” and each, an “Initial Purchaser Indemnified Party”) against any
loss, claim, damage, liability or expense, as incurred (collectively, “Losses” and each, a “Loss”), to which such Initial Purchaser Indemnified Party may become subject, under the Securities Act, the Exchange Act or
other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such Loss (or actions in respect
thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in any Company Additional Written Communication, the Pricing Disclosure Package or the Offering Memorandum
(or any amendment or supplement thereto) or the omission or alleged omission 

  
 20 









 
therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and to reimburse each Initial
Purchasers Indemnified Party for any and all expenses (including the reasonable fees and disbursements of counsel chosen by the Representatives) as such expenses are reasonably incurred by such Initial Purchaser Indemnified Party in connection with
investigating, defending, settling, compromising or paying any such Loss or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the
extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by any Initial Purchaser through the
Representatives expressly for use in any Company Additional Written Communication, the Pricing Disclosure Package or the Offering Memorandum (or any amendment or supplement thereto). The indemnity agreement set forth in this Section 8(a) shall
be in addition to any liabilities that the Company may otherwise have. 
 (b) Indemnification of the Company. Each
Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, each of its directors and officers and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act
(collectively, the “Company Indemnified Parties” and each, a “Company Indemnified Party”), against any Loss to which any Company Indemnified Party may become subject, under the Securities Act, the Exchange Act, or
other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Initial Purchaser), insofar as such Loss (or actions in
respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in any Company Additional Written Communication, the Pricing Disclosure Package or the Offering
Memorandum (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in
each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Company Additional Written Communication, the Pricing Disclosure Package or the Offering
Memorandum (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by such Initial Purchaser through the Representatives expressly for use therein; and to reimburse any Company
Indemnified Party for any and all expenses (including the reasonable fees and disbursements of counsel chosen by the Company) as such expenses are reasonably incurred by such Company Indemnified Party, in connection with investigating, defending,
settling, compromising or paying any such Losses or action. The Company hereby acknowledges that the only information furnished to the Company by any Initial Purchaser through the Representatives expressly for use in any Company Additional Written
Communication, the Pricing Disclosure Package or the Offering Memorandum (or any amendment or supplement thereto) are the statements set forth in the first sentence of the sixth paragraph, the second sentence of the ninth paragraph and the eleventh
and twelfth paragraphs under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and the Offering Memorandum. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that
each Initial Purchaser may otherwise have to the Company Indemnified Parties. 

  
 21 









 (c) Notifications and Other Indemnification Procedures. Promptly after receipt by an
indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party
in writing of the commencement thereof, but the failure to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained
in this Section 8 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying
party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving
the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, such indemnified party shall have the right to employ its own counsel in any
such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party, unless: (i) the employment of such counsel has been specifically authorized in writing by the
indemnifying party; (ii) the indemnifying party has failed promptly to assume the defense and employ counsel reasonably satisfactory to the indemnified party; or (iii) the named parties to any such action (including any impleaded parties)
include both such indemnified party and the indemnifying party or any affiliate of the indemnifying party, and such indemnified party shall have reasonably concluded that either (x) there may be one or more legal defenses available to it which
are different from or additional to those available to the indemnifying party or such affiliate of the indemnifying party or (y) a conflict may exist between such indemnified party and the indemnifying party or such affiliate of the
indemnifying party (it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to a single firm of local counsel) for all such indemnified parties, which firm shall be designated in writing by the
Representatives (in the case of counsel representing any Initial Purchaser Indemnified Party) and that all such reasonable fees and expenses shall be reimbursed as they are incurred). Upon receipt of notice from the indemnifying party to such
indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for
any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence, in
which case the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party. 
 (d) Settlements.
The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, but if settled with such consent or if there be a
final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any Loss by 

  
 22 









 
reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel as contemplated by this Section 8, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more
than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No
indemnifying party shall, without the prior written consent of the indemnified party, which consent shall not be unreasonably withheld, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit
or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional
release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf
of any indemnified party. 
 SECTION 9. Contribution. If the indemnification provided for in
Section 8 hereof is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any Losses referred to therein, then each indemnifying party shall contribute to the aggregate amount
paid or payable by such indemnified party, as incurred, as a result of any Losses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial
Purchasers, on the other hand, from the offering of the Notes pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only
the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such Losses, as
well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Notes pursuant to this Agreement shall be
deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes pursuant to this Agreement (before deducting expenses) received by the Company, and the total discount received by the Initial Purchasers, bear
to the aggregate initial offering price of the Notes. The relative fault of the Company, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged
untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or the Initial Purchasers, on the other hand, and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent such statement or omission. 
 The amount paid or payable
by a party as a result of the Losses referred to above shall be deemed to include, subject to the limitations set forth in Section 8, any reasonable legal or other fees or expenses reasonably incurred by such party in connection with
investigating or defending any action or claim. 

  
 23 









 The Company and the Initial Purchasers agree that it would not be just and equitable if
contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable
considerations referred to in this Section 9. 
 Notwithstanding the provisions of this Section 9, no Initial
Purchaser shall be required to contribute any amount in excess of the discount received by such Initial Purchaser in connection with the Notes purchased by it. No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 9 are several,
and not joint, in proportion to their respective purchase commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each Initial Purchaser Indemnified Party (other than such Initial Purchaser) shall have the
same rights to contribution as such Initial Purchaser, and each Company Indemnified Party (other than the Company) shall have the same rights to contribution as the Company. 
 SECTION 10. Default of One or More of the Several Initial Purchasers. If any one or more of the several Initial Purchasers shall fail or refuse to purchase Notes that it
or they have agreed to purchase hereunder on the Closing Date, and the aggregate principal amount of Notes, which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the aggregate
principal amount of the Notes to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportion to the aggregate principal amounts of such Notes set forth opposite their respective names on Schedule A bears
to the aggregate principal amount of such Notes set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Representatives with the consent of the non-defaulting Initial
Purchasers, to purchase such Notes which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on the Closing Date. If any one or more of the Initial Purchasers shall fail or refuse to purchase such Notes
and the aggregate principal amount of such Notes with respect to which such default occurs exceeds 10% of the aggregate principal amount of Notes to be purchased on the Closing Date, and arrangements satisfactory to the Representatives and the
Company for the purchase of such Notes are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8, 9 and 17 hereof shall at all
times be effective and shall survive such termination. In any such case, either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days in order that the required changes, if
any, to the Pricing Disclosure Package or the Offering Memorandum or any other documents or arrangements may be effected. 
 As
used in this Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 10. Any action taken under this Section 10 shall not relieve any
defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement. 

SECTION 11. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated
by the Representatives by notice given to the Company if at any time (i)

  
 24 









 
trading or quotation in any of the Company’s or KCS’s securities shall have been suspended or limited by the Commission or by any exchange or in any over-the-counter market, or trading
in securities generally on either the New York Stock Exchange, the American Stock Exchange, the Nasdaq Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange, the Chicago Board of Trade, or the Bolsa Mexicana de
Valores, S.A.B. de C.V. shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or the FINRA; (ii) a general banking moratorium shall have
been declared by any of federal, New York or Mexican authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity involving the United States or Mexico, or any change
in the United States, Mexican or international financial markets, or any substantial change or development involving a prospective substantial change in United States’, Mexico’s or international political, financial or economic conditions,
as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to market the Notes in the manner and on the terms described in the Pricing Disclosure Package or the Offering Memorandum or to enforce
contracts for the sale of securities; (iv) in the judgment of the Representatives there shall have occurred any Material Adverse Change; or (v) there shall have occurred a material disruption in commercial banking or securities settlement
or clearance services in the United States or in Mexico. Any termination pursuant to this Section 11 shall be without liability of any party to any other party except as provided in Sections 4 and 6 hereof, and provided further that
Sections 4, 6, 8, 9 and 17 hereof shall survive such termination and remain in full force and effect. 

SECTION 12. No Fiduciary Duty. The Company acknowledges and agrees that: (i) the purchase and sale of the
Notes pursuant to this Agreement, including the determination of the public offering price of the Notes and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several
Initial Purchasers, on the other hand, and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each
transaction contemplated hereby and the process leading to such transaction each Initial Purchaser is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of the Company or its affiliates, stockholders,
creditors or employees or any other party; (iii) no Initial Purchaser has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Company with respect to any of the transactions contemplated hereby or the process
leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Company on other matters) and no Initial Purchaser has any obligation to the Company with respect to the offering contemplated hereby except the
obligations expressly set forth in this Agreement; (iv) the several Initial Purchasers and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and that the
several Initial Purchasers have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with
respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate. 

  
 25 









 This Agreement supersedes all prior agreements and understandings (whether written or oral)
between the Company and the several Initial Purchasers with respect to the subject matter hereof. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the several Initial
Purchasers with respect to any breach or alleged breach of agency or fiduciary duty. 
 SECTION 13.
Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company, of its officers and of the several Initial Purchasers set forth in or made
pursuant to this Agreement (i) will remain operative and in full force and effect, regardless of any (A) investigation, or statement as to the results thereof, made by or on behalf of any Initial Purchaser, the officers or employees of any
Initial Purchasers, or any person controlling the Initial Purchaser, the Company, the officers or employees of the Company, or any person controlling the Company, as the case may be or (B) acceptance of the Notes and payment for them hereunder
and (ii) will survive delivery of and payment for the Notes sold hereunder and any termination of this Agreement.

 27 









 (a) Consent to Jurisdiction. Any legal suit, action or proceeding arising out of or
based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan, or
the courts of the State of New York in each case located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for
proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of the Specified Courts in any Related Proceeding. Service of any process,
summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any Related Proceeding brought in any Specified Courts. The parties irrevocably and unconditionally waive any objection to the
laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any Related Proceeding brought in any such court has been brought in an
inconvenient forum. Each party not located in the United States irrevocably appoints CT Corporation, as its agent to receive service of process or other legal summons for purposes of any Related Proceeding that may be instituted in any Specified
Court. 
 (b) Waiver of Immunity. With respect to any Related Proceeding, each party irrevocably waives, to the fullest
extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the
Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in
respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended. 

(c) Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into
any currency other than U.S. dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Initial Purchasers
could purchase U.S. dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligations of the Company in respect of any sum due from it to any Initial Purchaser shall,
notwithstanding any judgment in any currency other than U.S. dollars, not be discharged until the first business day, following receipt by such Initial Purchaser of any sum adjudged to be so due in such other currency, on which (and only to the
extent that) such Initial Purchaser may in accordance with normal banking procedures purchase U.S. dollars with such other currency; if the U.S. dollars so purchased are less than the sum originally due to such Initial Purchaser hereunder, the
Company agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Initial Purchaser against such loss. If the U.S. dollars so purchased are greater than the sum originally due to such Initial Purchaser hereunder, such
Initial Purchaser agrees to pay to the Company an amount equal to the excess of the U.S. dollars so purchased over the sum originally due to such Initial Purchaser hereunder.

page to this Agreement by telecopier, facsimile or other electronic transmission (i.e., a “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart thereof. This Agreement may not be amended or modified

(i) as part of its distribution at any time and (ii) otherwise until 40 days after the later of the commencement of the offering of the Notes pursuant hereto and the Closing Date, other than in accordance with Regulation S or another
