Ladies and Gentlemen:

The United Mexican States (“Mexico”) proposes to make an invitation to owners (each, a "Bondholder”) of its outstanding U.S. $2,025,434,000 8.125% Global Bonds due 2019, U.S. $1,049,193,000 8.00% Global Notes due 2022, U.S. $533,664,000 11.50% Global Bonds due 2026, U.S. $2,691,426,000 8.30% Global Notes due 2031 and U.S. $2,485,878,000 7.500% Global Notes due 2033 (the “Old Bonds”), to submit one or more offers (i) to exchange Old Bonds for 6.75% Global Notes due 2034 (the “Reopened Notes”) and a U.S. dollar amount in cash, and/or (ii) to sell Old Bonds to Mexico for a U.S. dollar amount in cash (each such offer, an “Offer” and collectively the “Offers”) on the terms and subject to the conditions set forth in an invitation supplement dated as of the date hereof (the “Invitation Supplement” and, together with the prospectus supplement and the prospectus dated April 10, 2006 referred to therein, the “Invitation”). Capitalized terms used but not defined herein shall have the meanings ascribed to them in the dealer managers agreement, dated as of the date hereof (the “Dealer Managers Agreement”), among Mexico, Barclays Capital Inc. and Morgan Stanley & Co. Incorporated, as dealer managers (the “Dealer Managers”).

2. (a) Mexico hereby appoints Bondholder Communications Group, LLC, as exchange agent (in such capacity, the “Exchange Agent”) and information agent (in such capacity, the “Information Agent”) and Kredietbank S.A. Luxembourgeoise, as Luxembourg exchange agent (the “Luxembourg Exchange Agent” and, together with the Exchange Agent and the Information Agent, the “Agents”) and authorizes them to act as such in connection with the Invitation pursuant to this exchange and information agent agreement (this “Agreement”). The Exchange Agent agrees to perform those services in connection with the Invitation as are customarily performed by exchange agents in connection with invitations and offers of like nature, including, but not limited to (i) performing the duties of the Exchange Agent described in the Invitation, including but not limited to maintaining the Invitation Website (as defined in the Invitation Supplement) and receiving and processing electronic letters of transmittal with respect to Offers submitted over such website, (ii) receiving from The Depository Trust company (“DTC”), Euroclear Bank, S.A./N.V., as operator of the Euroclear System (“Euroclear”) and Clearstream Banking, société anonyme (“Clearstream, Luxembourg”) details of any Bond Instructions received by them from Bondholders, (iii) instructing DTC, Euroclear and Clearstream, Luxembourg as to the Exchange Agent’s ATOP account at DTC described in

Section 2(c) to which the Old Bonds offered in connection with the Invitation should be delivered (collectively, the “DTC ATOP Account”) and (iv) instructing DTC to deliver the Old Bonds with ISIN numbers US593048BN00 and US 593048AX90 to account #2426 at DTC of Citibank, New York (Agency and Trust Department); for cancellation upon completion of the sale and exchange, and to deliver Old Bonds with ISIN numbers US91086QAJ76, US91086QAG38, US91086QAN88 to account #2790 at DTC of Citibank, New York for cancellation upon the completion of the sale and exchange. The Luxembourg Exchange Agent agrees to perform the services set forth in the Invitation Supplement to be performed by it, and shall immediately forward any Offers received by it to the Exchange Agent, and shall advise the relevant Bondholders that Offers may only be submitted through the Invitation Website. Mexico shall have sole responsibility and authority for the acceptance or rejection of any and all Offers and may, acting through any of the Deputy Undersecretary for Public Credit, the Deputy General Director of Debt Issuance or the Deputy General Director of Legal Procedures of Credit of the Ministry of Finance and Public Credit (such action, if given orally, to be confirmed in writing), or any other party (an “Authorized Person”) designated by any of such officials of the Ministry of Finance and Public Credit, waive any irregularities and defects in connection with any Offer made or electronic letters of transmittal submitted pursuant to the Invitation.

(b) The Exchange Agent shall advise Mexico and the Dealer Managers daily (or more frequently if requested in writing) in writing of all Offers made or withdrawn during the preceding day, the principal amount and series of Old Bonds so offered or withdrawn by, and the Offer Spread Differential (as defined in the Invitation Supplement) specified in the case of any competitive offer (as such term is used in the Invitation Supplement), by each such offering or withdrawing direct participant on behalf of a Bondholder. Any Offer may be withdrawn prior to 5:00 p.m. (New York time) on the Expiration Date in accordance with the procedures set forth in the Invitation Supplement under the heading “The Invitation—Irrevocability; Withdrawal Rights.” Not later than 7:00 p.m. (New York time) on the Expiration Date, the Exchange Agent will provide at least two files to each of Mexico and the Dealer Managers, each in a format agreed to by Mexico and the Dealer Managers, one including all Offers submitted to exchange Old Bonds for Reopened Notes and the other all Offers submitted to sell Old Bonds for cash, and each of such files shall include, in respect of each such Offer, the Offer Spread Differential, the name of the direct participant making each such Offer, the principal amount and series of Old Bonds validly offered in proper form, rejected (in a separate sheet) or being processed (also in a separate sheet) and, in the case of each Offer to sell Old Bonds for cash, whether the Bondholder wishes to have any Old Bonds subject to proration resubmitted in exchange for Reopened Notes in the form of a non-competitive Offer.

(c) The Exchange Agent will receive Old Bonds into the DTC ATOP Account at DTC in connection with the Invitation. Any financial institution that is a participant in DTC may effect a transfer of Old Bonds through DTC’s Automated Tender Offer Program (“ATOP”) by causing DTC to transfer such Old Bonds into the DTC ATOP Account in accordance with DTC’s procedures, and the Exchange Agent may effect a withdrawal of Old Bonds through such account by book-entry movement. However, although delivery of Old Bonds may be effected through book-entry transfer through the ATOP system, an electronic letter of transmittal and any other required documents must, in any case, be received by the Exchange Agent in order for an Offer to have been validly made with respect to such Old Bonds. Notwithstanding the foregoing,

Mexico and the Exchange Agent have agreed that Euroclear and Clearstream, Luxembourg may transfer the Old Bonds offered by their participants on behalf of beneficial owners directly into the DTC ATOP Account by effecting a transfer of Old Bonds through DTC’s ATOP system, and that the Dealer Managers may vouch for Offers made by their customers; provided that (1) in the case of Offers submitted by Euroclear or Clearstream, Luxembourg participants, (A) each such participant submits an electronic letter of transmittal via the Invitation Website with respect to its Offer and (B) Euroclear or Clearstream, Luxembourg forwards to the Exchange Agent by tested telex or SWIFT communication confirmation of the Bond Instructions (as defined in the Invitation Supplement) received with respect to such Offer and the information required to reconcile such participant’s Bond Instructions with its electronic letter of transmittal with respect to each Offer and (2) in the case of Offers vouched for by a Dealer Manager, such Dealer Manager’s customer’s custodian bank (A) submits an electronic letter of transmittal via the Invitation Website with respect to each such Offer or otherwise submits the relevant information, together with an agreement to be bound by the terms of the electronic letter of transmittal and (B) delivers or causes to be delivered Bond Instructions with respect to each such Offer no later than the second Business Day (as defined in the Invitation Supplement) following the Announcement Date.

(d) As soon as practicable but in no event later than 5:00 p.m. (New York time) on the Business Day immediately following the Expiration Date, the Exchange and Information Agent shall confirm to Mexico and the Dealer Managers that (i) the principal amount of Old Bonds held through DTC relating to each Offer (other than Offers submitted by the Dealer Managers) specified in an electronic letter of transmittal has been transferred via DTC’s ATOP system to the DTC ATOP Account and (ii) the principal amount of Old Bonds held through Euroclear or Clearstream, Luxembourg and specified by them as being the subject of Offers submitted by their participants (other than the Dealer Managers) has been blocked in accordance with Bond Instructions received by the relevant clearing system.

(e) As soon as practicable but in no event later than 5:00 p.m. (New York time) on the third Business Day immediately following the Expiration Date, the Exchange and Information Agent shall confirm to Mexico and the Dealer Managers that (i) the principal amount of Old Bonds held through DTC relating to all Offers vouched for by the Dealer Managers has been transferred to the DTC ATOP Account and (ii) the principal amount of Old Bonds held through Euroclear or Clearstream, Luxembourg and specified by them as being the subject of Offers vouched for by the Dealer Managers has been blocked in accordance with Bond Instructions received by the relevant clearing system.

(f) In addition, the Exchange Agent shall keep Mexico and the Dealer Managers informed on a daily basis during the period from the Expiration Date until the Settlement Date as to the principal amount of Old Bonds subsequently transferred into the DTC ATOP Account or such other accounts and as to the progress of its confirmation efforts and cooperate with and assist them in resolving any reconciliation problems (x) between electronic letter of transmittal received by the Exchange Agent and transfers of Old Bonds into the DTC ATOP Account or defects in electronic letters of transmittal and (y) between the information regarding Offers received from Euroclear, Clearstream, Luxembourg and the Dealer Managers

and the principal amount of Old Bonds transferred into the Exchange Agent’s DTC ATOP Account.

(g) By 10:00 a.m. (New York time) on the fourth Business Day preceding the Settlement Date, the Exchange Agent shall provide, and shall be authorized to so provide, to Mexico, with a copy to Cleary Gottlieb Steen & Hamilton LLP and the Dealer Managers, a list specifying (i) each series and principal amount of Old Bonds relating to any Offer submitted by a direct participant of DTC, Euroclear or Clearstream, Luxembourg, the name of such participant, such participant’s account number at such relevant clearing system and whether such Offer was for exchange only, sale for cash with reallocation in case of proration, or sale for cash only, (ii) the series and principal amount of Old Bonds offered by each such direct participant that were accepted by Mexico for exchange or purchase, if applicable, (iii) the series and principal amount of Old Bonds offered by each such direct participant that were not accepted for exchange or purchase, if applicable, (iv) the Reopened Notes to be issued in exchange for the Old Bonds offered by such direct participant that were accepted for exchange, (v) if proration occurs and promptly after receipt from Mexico or the Dealer Managers by the Exchange Agent of the proration instructions reasonably necessary for the Exchange Agent to so provide, (1) the series and principal amount of Old Bonds offered by each such direct participant that are subject to proration and (2) the series and aggregate principal amount of such Old Bonds subject to proration that are to be accepted by Mexico after proration is made, and (vi) if applicable, a breakdown of the cash payment to be made to each such direct participant in respect of (1) the U.S. dollar amount in cash to be paid to Bondholders who submit Offers to exchange Old Bonds and (2) the U.S. dollar amount in cash to be paid to Bondholders who submit Offers to sell Old Bonds for cash.

(j) The Exchange Agent shall calculate, as directed by Mexico, based on rates and methods of calculation supplied by Mexico (1) the U.S. dollar amount in cash to be paid to Bondholders who submit Offers to exchange Old Bonds (including Cash Payments (as defined in the Invitation Supplement) and amounts payable in respect of rounding) and (2) the U.S. dollar amount in cash to be paid to Bondholders who submit Offers to sell Old Bonds for cash payable to each account at DTC, Euroclear and Clearstream, Luxembourg as specified in the electronic letters of transmittal or in the SWIFT or tested telex information received from the clearing systems and the Dealer Managers.

9. Mexico represents and warrants to each Agent that:

(a) this Agreement has been duly authorized, executed and delivered by Mexico and constitutes the valid and binding agreement of Mexico enforceable against Mexico in accordance with its terms, subject to laws of general applicability relating to or affecting creditors’ rights and to general equitable principles, and subject, as to Section 11 of this Agreement, to any limitations imposed by the securities laws or any other applicable law of any applicable jurisdiction;

(b) the Reopened Notes will be duly authorized, and, when executed, issued, authenticated and delivered pursuant to the Invitation and the Fiscal Agency Agreement, will have been duly executed, issued and delivered and will constitute valid and legally binding obligations of Mexico entitled to the benefits provided by the Fiscal Agency Agreement; and

11. Mexico covenants and agrees to indemnify and hold harmless each Agent and its officers, directors, employees, and agents (collectively, the “Indemnified Parties” and, each, an "Indemnified Party”) against any loss, liability or reasonable and documented cost or expense (including reasonable and documented attorneys’ fees and expenses) incurred in each case without gross negligence, willful misconduct or bad faith and in connection with the administration of the duties of the Indemnified Parties hereunder in accordance with this Agreement; provided that promptly after, but in any event within 10 days of, receipt by such Indemnified Party of a written assertion of a claim or any other action commenced against it for which it will seek indemnity pursuant to this Section 11 (a “Claim”), such Indemnified Party shall notify Mexico by letter, or by telecopier confirmed by letter of the Claim; and provided, further, that the omission so to notify Mexico shall not relieve it from any liability which it may have to the Indemnified Party, except to the extent that Mexico is materially adversely affected by such omission. Mexico shall be entitled to participate at its own expense in the defense of any such claim or other action and if Mexico so elects, Mexico shall assume the defense of any suit brought to enforce any such claim. In the event that Mexico shall assume the defense of any such suit, Mexico shall not be liable for the fees and expenses of any additional counsel thereafter retained by such Indemnified Party so long as Mexico shall retain counsel reasonably satisfactory to such Indemnified Party to defend such suit, unless such Indemnified Party’s counsel reasonably determines that a conflict of interest exists, in which case Mexico shall remain liable for such Indemnified Party’s reasonable and duly documented fees and expenses of counsel. No Indemnified Party shall settle any claim for which it seeks indemnity hereunder without the prior written consent of Mexico, which consent shall not be unreasonably withheld or delayed. The provisions of this Section 11 shall survive the termination of this Agreement.

12. In the event that any provision hereof shall be determined to be invalid or unenforceable in any respect, such determination shall not, to the extent permitted by law, affect any other provision hereof, which shall remain in full force and effect.

13. This Agreement may be executed in one or more separate counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Facsimile signatures shall be deemed to be originals for all purposes hereunder.

14. This Agreement, including any rights to indemnity and contribution hereunder, shall inure to the benefit of and be binding upon Mexico, each Agent and the other persons entitled to indemnity and contribution under Section 11. Nothing in this Agreement is intended, or shall be construed, to give to any other person or entity any right hereunder or by virtue hereof. Neither this Agreement nor any interest herein or obligation hereunder may be

transferred or assigned without the prior written consent of the other party hereto and any purported transfer or assignment without such consent shall be null and void.

15. This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements, understandings and arrangements, oral or written, between the parties hereto with respect to the subject matter hereof.

16. This Agreement may not be amended except in writing signed by each party to be bound thereby.

17. This Agreement shall terminate upon the termination or withdrawal of the Invitation or, as to such Agent, upon withdrawal by the Exchange Agent, Information Agent or Luxembourg Exchange Agent from its respective appointment hereunder, it being understood that Section 11 hereof shall survive any termination of this Agreement.

18. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK, EXCEPT THAT AUTHORIZATION AND EXECUTION OF THIS AGREEMENT BY MEXICO SHALL BE GOVERNED BY THE LAWS OF THE UNITED MEXICAN STATES.

19. Mexico hereby appoints its Consul General in The City of New York (currently Mr. José Evaristo Ramón Xitotl Ramírez) and his successors as its process agent (the “Process Agent”) upon which process may be served in any action or proceeding arising out of or relating to this Agreement that may be instituted in any state or federal court in the Borough of Manhattan, The City of New York, and each of the parties hereto irrevocably submits to the jurisdiction of any such court in respect of any such action and irrevocably waives any objection which it may now or hereafter have to the laying of venue of any such action in any such court. Mexico waives any right to which it may be entitled on account of residence or domicile. Mexico will maintain at all times in the Borough of Manhattan, The City of New York, a person acting as or discharging the function of Consul General as long as this Agreement remains outstanding, unless and until a successor agent shall have been appointed and such successor agent shall have accepted such appointment. Mexico will take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment or appointments in full force and effect as aforesaid. Service of process upon the Process Agent at 27 East 39th Street, New York, New York 10016, and written notice of such service mailed or delivered to Mexico at its address set forth in Section 20(c) hereof shall be deemed, in every respect, effective service of process upon Mexico. Notwithstanding the foregoing, any such action may be instituted in any competent court in Mexico. Mexico hereby waives irrevocably any immunity from jurisdiction to which it might otherwise be entitled (including sovereign immunity and immunity from pre-judgment attachment, post-judgment attachment and execution) in any such action in any state or federal court in the Borough of Manhattan, The City of New York, or in any competent court in Mexico, except that under Article 4 of the Federal Code of Civil Procedures of Mexico attachment prior to judgment or attachment in aid of execution will not be enforced by Mexican courts against property of Mexico. The submission to jurisdiction and waiver of immunity by Mexico contained herein is

for the exclusive benefit of the Agents (and their respective officers, directors, agents and employees referred to in Section 11 hereof) and shall not extend to any other person.
