Ladies and Gentlemen:

The United Mexican States (“Mexico”), confirms its agreement with each of you with respect to the issue and sale by Mexico of up to U.S. $50,000,000,000 (or its equivalent in other currencies or currency units) aggregate principal amount (or aggregate initial offering price, as the case may be) of its Global Medium-Term Notes, Series A, Due Nine Months or More from Date of Issue (the “Notes”). As of February [ ], 2005, of such U.S. $50,000,000,000, Notes with an aggregate principal amount of U.S. $22,073,852,700 have been issued and sold in the United States and Notes with an aggregate principal amount (or aggregate initial offering price, as the case may be) equal or equivalent to U.S. $16,509,406,053 have been sold outside the United States. From and after the date hereof, Notes with an aggregate principal amount (or aggregate initial offering price, as the case may be) not to exceed U.S. $11,416,741,247 (or its equivalent in other currencies or currency units) may be issued and sold hereunder, and U.S. $3,951,406,915 of such amount of Notes may be issued and sold in the United States. The Notes will be issued under a fiscal agency agreement dated as of September 1, 1992, as amended (the “Fiscal Agency Agreement”) between Mexico and Citibank, N.A., as fiscal agent (the “Fiscal Agent”) and the authorization certificate of Mexico pursuant to Section 1(b) thereto dated February [ ], 2005 (the “Authorization”). Unless otherwise specifically provided for and set forth in a Pricing Supplement (as defined below), the Notes denominated and payable in U.S. dollars will be issued in denominations of U.S. $1,000 and integral multiples of U.S. $1,000. The authorized denominations of Notes denominated in currencies (including composite currencies) other than U.S. dollars will be set forth in an applicable Pricing Supplement. The Notes may be issued in registered or bearer form. The Notes will have the interest rates, maturities and, if applicable, other terms set forth in the applicable Pricing Supplement. The Notes will be issued, and the terms thereof established, in accordance with the Fiscal Agency Agreement, the Authorization and any Terms Agreement (as defined in Section 2(b)). For the purposes of this agreement (the “Agreement”), the term “Agent” shall refer to any of you acting solely in the capacity as agent for Mexico pursuant to Section 2(a) and not as principal (collectively, the “Agents”); the term “Purchaser” shall refer to one of you acting solely as principal pursuant to Section 2(b) and not as agent; and the term “you” shall refer to you collectively whether at any time any of you is acting in both such capacities or in either such capacity. In acting under this Agreement, in whatever capacity, each of you is acting individually and not jointly, unless otherwise specified in the applicable Terms Agreement.

All references in this Agreement to principal, premium and interest in respect of the Notes shall, unless the context otherwise requires, be deemed to include all additional amounts, if any, payable in respect thereof as a result of any withholding or deduction for or on account of any present or future taxes, duties, assessments or governmental charges of whatever nature imposed or levied by Mexico or any political subdivision or any taxing authority in Mexico as set forth in the Notes.

1. Representations and Warranties. Mexico represents and warrants to, and agrees with, you as set forth below in this Section 1. Certain terms used in this Section 1 are defined in paragraph (k) hereof.

(a) Mexico meets the requirements for use of Schedule B under the Securities Act of 1933, as amended (the “Act”), is a seasoned foreign government within the meaning of Commission Release No. 33-6424 and has filed with the Securities and Exchange Commission (the “Commission”) registration statements on such Schedule (File Nos. 333-[ ] and 333-110594), including a basic prospectus, which have become effective for the registration under the Act of U.S. $3,951,406,915 (or its equivalent in other currencies or currency units) aggregate principal amount (or aggregate initial offering price, as the case may be) of debt securities or warrants (the “Securities”), including the Notes. Such registration statements meet the requirements set forth in Commission Release No. 33-6424 and comply in all other material respects with such Release. Mexico has included in such registration statements, or has filed or will file with the Commission pursuant to the applicable paragraph of Rule 424(b) under the Act, a supplement to the prospectus included in such registration statements relating to the Notes and the plan of distribution thereof (the “Prospectus Supplement”). In connection with the sale of Notes in the United States, Mexico proposes to file with the Commission pursuant to the applicable paragraph of Rule 424(b) under the Act further supplements to the Prospectus Supplement (each, a “Pricing Supplement”) specifying the principal amount, interest rates, maturity dates and, if appropriate, other terms of such Notes sold pursuant hereto or the offering thereof.

(b) As of the Execution Date, on the Effective Date, when any supplement to the Prospectus is filed with the Commission, as of the date of a Terms Agreement and at the date of delivery by Mexico of any Notes sold hereunder (a “Closing Date”), (i) the Registration Statement, as amended as of any such time, and the Prospectus, as supplemented as of any such time, will comply in all material respects with the applicable requirements of the Act and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the respective rules thereunder; (ii) the Registration Statement, as amended as of any such time, did not or will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; and (iii) the Prospectus, as supplemented as of any such time, will not 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, however, that Mexico makes no representations or warranties as to the information contained in or omitted from the Registration Statement or the Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to Mexico by any of you specifically for inclusion in the Registration Statement or the Prospectus (or any supplement thereto).

(c) Subsequent to the respective dates as of which information is given in the Registration Statement and the Prospectus, except as set forth in or contemplated by the Registration Statement and the Prospectus, there has not been any material adverse change in or affecting the financial, economic, political or other condition of Mexico.

(d) All necessary action by or on behalf of Mexico has been taken or will have been taken prior to the Closing Date, and prior to such date any necessary approvals or consents required under the laws of Mexico will have been duly obtained, and on such date will be in full force and effect, for the authorization, execution and delivery of this Agreement, the Fiscal Agency Agreement, the Authorization and any Terms Agreement and for the issuance and sale of Notes by Mexico under this Agreement including, without limitation, the Presidential Decree permitting issuances of Notes and the delegation of authority (the “Delegation of Authority”) issued by the Secretary of Finance and Public Credit.

(e) The Notes have been duly authorized and, when executed and authenticated in accordance with the Fiscal Agency Agreement and delivered to and paid for by the purchasers thereof against payment therefore in accordance with the terms hereof, will be entitled to the benefits of the Fiscal Agency Agreement and will constitute valid and legally binding, direct, general and unconditional External Indebtedness of Mexico (as defined below) enforceable in accordance with their terms. The full faith and credit of Mexico has been pledged for the due and punctual payment of principal of, interest on, and premium, if any, on the Notes, and the Notes will rank pari passu, without any preference among themselves with all other unsecured and unsubordinated obligations of Mexico, present and future, relating to External Indebtedness; and the Notes and the Fiscal Agency Agreement will conform to the descriptions thereof in the Prospectus. For purposes of this paragraph (e), “External Indebtedness” means any Indebtedness which is payable by its terms or at the option of its holder in any currency other than the currency of Mexico (other than any such indebtedness that is originally issued or incurred within Mexico) and “Indebtedness” means all unsecured and unsubordinated obligations of Mexico in respect of moneys borrowed by Mexico and guarantees of Mexico in respect of moneys borrowed by others.

(f) Other than as set forth in the Prospectus, there are no legal or governmental proceedings pending to which Mexico is a party or of which any of its properties is the subject which, if determined adversely to Mexico, would individually or in the aggregate have a material adverse effect on Mexico’s ability to perform its obligations under the Notes, this Agreement, the Fiscal Agency Agreement, the Authorization or any Terms Agreement; and, to the best of Mexico’s knowledge, no such proceedings have been threatened.

(g) Mexico is not in default in the payment of principal, interest or any other amounts owing on any obligation in respect of indebtedness for money borrowed and Mexico has not received any notice of default (other than with respect to any failure to deliver periodically economic or financial information pursuant to agreements relating to Mexico’s indebtedness) or acceleration with respect to any obligation in respect of indebtedness for money borrowed; and the issuance and sale of the Notes and the compliance by Mexico with all of the provisions of the Notes, the Fiscal Agency Agreement, the Authorization and this Agreement and the consummation of the transactions herein and therein contemplated will not conflict with or result in a breach of any of the terms or provisions of, or constitute a default under, any treaty, convention, material agreement or material instrument to which Mexico is a party or by which it is bound and will not result in the creation or imposition of any mortgage, lien, charge or encumbrance of any nature whatsoever upon any of the revenues or assets of Mexico under any such agreement or instrument and will not infringe any law or regulation of Mexico.

(h) There is no tax, levy, deduction, charge or withholding imposed by Mexico or any political subdivision thereof either (i) on or by virtue of the execution, delivery or enforcement of this Agreement, the Fiscal Agency Agreement, the Authorization or any Terms Agreement or (ii) on any payment to be made by Mexico hereunder or any payment of principal, interest or additional amounts, if any, under any Note, provided that such Note is held by an individual who is not a resident of Mexico or by a non-Mexican corporation directly and not through a permanent establishment thereof in Mexico.

(i) The issuance of Notes by Mexico hereunder and under the Fiscal Agency Agreement and the Authorization complies with, and is within the limits set forth in, Mexico’s Federal Revenue Law for the Fiscal Year 2004.

(j) The use given by Mexico to the proceeds of any issue of Notes would not impair Mexico’s obligations thereunder.

(k) The terms which follow, when used in this Agreement, shall have the meanings indicated. The term “Effective Date” shall mean each date that the Registration Statement and any post-effective amendment or amendments thereto became or become effective and each date after the date hereof on which a document incorporated by reference in the Registration Statement is filed. “Execution Date” shall mean the date that this Agreement is executed and delivered by the parties hereto. “Basic Prospectus” shall mean the form of basic prospectus relating to the Securities contained in the registration statement under Schedule B, File No. 333-[ ] as amended at the effective date thereof. “Prospectus” shall mean the Basic Prospectus as supplemented by the Prospectus Supplement. “Registration Statement” shall mean the registration statements referred to in paragraph (a) above, including incorporated documents, exhibits and financial statements, as amended, and, with respect to the registration statement under Schedule B, File No. 333-110594, shall include the Basic Prospectus and Prospectus Supplement relating thereto filed pursuant to Rule 424 with the registration statement on Schedule B, File No. 333-[ ]. “Rule 424” refers to such rule under the Act.

(a) Subject to the terms and conditions set forth herein, Mexico hereby authorizes each of the Agents to act as its agent to solicit offers for the purchase of all or a portion of the Notes from Mexico.

On the basis of the representations and warranties and subject to the terms and conditions set forth herein, each of the Agents agrees, as agent of Mexico, to use its reasonable best efforts to solicit offers to purchase the Notes from Mexico upon the terms and conditions set forth in the Prospectus (and any supplement thereto). Each Agent shall make reasonable best efforts to assist Mexico in obtaining performance by each purchaser whose offer to purchase Notes has been solicited by such Agent and accepted by Mexico, but such Agent shall not, except as otherwise provided in this Agreement, be obligated to disclose the identity of any purchaser or have any liability to Mexico in the event any such purchase is not consummated for any reason. Except as provided in Section 2(b), under no circumstances will any Agent be obligated to purchase any Notes for its own account. It is understood and agreed, however, that any Agent may purchase Notes as principal pursuant to Section 2(b).

Mexico reserves the right, in its sole discretion, to instruct the Agents to suspend at any time, for any period of time or permanently, the solicitation of offers to purchase Notes. Upon receipt of instructions from Mexico, the Agents will forthwith suspend solicitation of offers to purchase Notes from Mexico until such time as Mexico has advised them that such solicitation may be resumed.

Subject to the provisions of this Section, offers for the purchase of Notes may be solicited by an Agent as agent for Mexico at such time and in such amounts as such Agent deems advisable. Mexico reserves the right to (i) solicit and accept offers to purchase and to sell Notes directly to purchasers on its own behalf and (ii) to appoint one or more brokers or dealers other than the Agents to act as agents to solicit offers for the purchase of Notes (or to purchase the Notes as principal as described in paragraph (b) below) (“Additional Agents”); provided, however, that (a) each such Additional Agent shall become a party to this Agreement (and thereafter the term “Agent” as used herein shall mean the Agents and such Additional Agents (other than Additional Agents appointed for purposes of a particular issue of Notes)) and (b) the Agents are given notice of such appointment. Any Additional Agent appointed pursuant to this Section 2 shall execute and deliver to Mexico an instrument accepting such appointment hereunder and without any further act, deed or conveyance, shall become vested with all authority, right, powers, immunities, duties and obligations with like effect as if originally named as a party to this Agreement. Any such appointment of an Additional Agent may be limited to a particular issue of Notes. In the case of any sale not resulting from a solicitation made by any Agent, no commission shall be payable to any Agent.

(b) Subject to the terms and conditions stated herein, whenever Mexico and any of you determines that Mexico shall sell Notes directly to any of you (or to any other broker or dealer) as principal, each such sale of Notes shall be made in accordance with the terms of this Agreement and a supplemental agreement relating to such sale. Each such supplemental agreement (which shall be in writing and signed by an official named in a certificate of delegation of authority) is herein referred to as a “Terms Agreement.” Unless the context otherwise requires, each reference contained herein to “this Agreement” shall be deemed to include any applicable Terms Agreement between Mexico and a Purchaser and express mention of Terms Agreements in any provisions hereof shall not be construed as excluding Terms Agreements in those provisions hereof where such express mention is not made. Each Terms Agreement shall describe the Notes to be purchased by the Purchaser pursuant thereto and shall specify the aggregate principal amount of such Notes, the price to be paid to Mexico for such Notes, the maturity date of such Notes, the rate at which interest will be paid on such Notes, the dates on which interest will be paid on such Notes and the record date with respect to each such payment of interest, the Closing Date for the purchase of such Notes, the place of delivery of the Notes and payment therefor, the method of payment and any additional requirements for the delivery of opinions of counsel, certificates from Mexico or its officers as described in Section 6(b). Any such Terms Agreement may also specify the period of time referred to in Section 4(r). Each written Terms Agreement shall be substantially in the form attached hereto as Exhibit A. The Purchaser’s commitment to purchase Notes shall be deemed to have been made on the basis of the representations and warranties of Mexico herein contained and shall be subject to the terms and conditions herein set forth.

Delivery of the certificates for Notes sold to the Purchaser pursuant to a Terms Agreement shall be made not later than the Closing Date agreed to in such Terms Agreement, against payment of immediately available funds (or such other consideration as is agreed between Mexico and such Purchaser) to the account specified by Mexico in the net amount due to Mexico for such Notes.

Any Note sold to a Purchaser (i) shall be purchased by such Purchaser at a percentage of the principal amount thereof specified in the Terms Agreement less a percentage equal to the commission specified in the Terms Agreement and (ii) may be resold by such Purchaser at varying prices from time to time or, if set forth in the applicable Terms Agreement and Pricing Supplement, at a fixed public offering price. In connection with any resale of Notes purchased, a Purchaser may use a selling or dealer group and may reallow to any broker or dealer any portion of the discount or commission payable pursuant hereto.

Terms used in this paragraph have the meanings given to them by the U.S. Internal Revenue Code and regulations thereunder, including the D Rules.

4. Covenants. Mexico agrees with you that:

(a) Prior to the termination of the offering of the Notes (including by way of resale by a Purchaser of Notes), Mexico will not file any amendment of the Registration Statement or supplement to the Prospectus (except for (i) periodic or current reports filed under the Exchange Act, (ii) a supplement relating to any offering of Notes providing solely for the specification of or a change in the maturity dates, interest rates, issuance prices or other terms of any Notes or (iii) a supplement relating to an offering of Securities other than the Notes) unless Mexico has furnished each of you a copy for your review prior to filing and given each of you a reasonable opportunity to comment on any such proposed amendment or supplement. Subject to the foregoing sentence, in connection with an issue of Notes being offered in the United States or being resold into the United States within the period during which a prospectus is required to be delivered, Mexico will cause each supplement to the Prospectus to be filed with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to you of such filing. Mexico will promptly advise each of you (i) when the Prospectus, and any supplement thereto, shall have been filed with the Commission pursuant to Rule 424(b), (ii) when, prior to termination of any offering of Notes, any amendment of the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission for any amendment of the Registration Statement or supplement to the Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose and (v) of the receipt by Mexico of any notification with respect to the suspension of the qualification of the Notes for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose. Mexico will use its best efforts to prevent the issuance of any such stop order and, if issued, to obtain as soon as possible the withdrawal thereof.

(b) If, at any time when a prospectus relating to the Notes is required to be delivered under the Act, any event occurs as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if for any other reason it shall be necessary to amend the Registration Statement or to supplement the Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, Mexico promptly will (i) notify each of you to suspend solicitation of offers to purchase Notes (and, if so notified by Mexico, each of you shall forthwith suspend such solicitation and cease using the Prospectus as then supplemented), (ii) prepare and file with the Commission, subject to the first sentence of paragraph (a) of this Section 4, an amendment or supplement which will correct such statement or omission or effect such compliance and (iii) supply any supplemented Prospectuses to each of you in such quantities as you may reasonably request; provided, however, that in the event that any Agent is required to deliver a prospectus relating to any Notes at any time nine months or more after the Closing Date with respect to such Notes, such Agent shall reimburse Mexico for its reasonable and documented out-of-pocket expenses (including the legal fees and disbursements of its counsel) in connection with the preparation and filing of such amendment or supplement and the furnishing to such Agent of such supplemented Prospectuses. Mexico’s obligations to update the Prospectus pursuant to Sections 4(l), 4(m) and 4(n) hereof, including payment of any expenses incurred by Mexico in connection therewith, shall not be affected by the preceding sentence.

If such amendment or supplement, and any documents, certificates and opinions furnished to each of you pursuant to paragraph (j) of this Section 4 in connection with the preparation or filing of such amendment or supplement are satisfactory in all respects to you, you will, upon the filing of such amendment or supplement with the Commission and upon the effectiveness of an amendment to the Registration Statement, if such an amendment is required, resume your obligation to solicit offers to purchase Notes hereunder.

(c) Mexico will make generally available to its security holders in the United States and to each of you as soon as practicable, a statement of Mexico’s revenues and expenditures for the first full fiscal year commencing after the date hereof which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act.

(d) Mexico will furnish to each of you and your counsel, without charge, copies of the Registration Statement (including exhibits and all amendments thereto) and, so long as delivery of a prospectus may be required by the Act, as many copies of the Prospectus and any supplement thereto as you may reasonably request.

(e) Mexico will arrange for the qualification of the Notes for sale under the laws of such jurisdictions of the United States and Canada as any of you may designate and such other jurisdictions as Mexico and you shall agree upon and will maintain such qualifications in effect so long as required for the distribution of the Notes; provided, however, that in connection therewith Mexico shall not be required to take any action that would subject it to general or unlimited service of process in any jurisdiction where it is not at the date hereof subject.

(f) So long as any of the Notes are outstanding, Mexico will furnish to each of you copies of all reports filed by it with the Commission.

(g) So long as any of the Notes are outstanding, Mexico will furnish to each of you upon request, as soon as practicable after the availability thereof, a copy of Mexico’s annual federal budget and revenue law.

(h) So long as any of the Notes are outstanding, Mexico will obtain and maintain in full force and effect all governmental approvals which may be necessary under the laws of Mexico for the performance of Mexico’s obligations under the Notes or for the validity or enforceability thereof or hereof and duly take all necessary and appropriate governmental and administrative action in Mexico in order to permit all payments to be made under the Notes in accordance with their terms including, without limitation, causing that payments made pursuant to the Notes be included in Mexico’s Annual Federal Budget.

(i) Mexico will file an application to register the Notes with the Special Section of the Registro Nacional de Valores (the “National Registry”) maintained by the Comisión Nacional Bancaria y de Valores (the “National Banking and Securities Commission”) and will, if requested, provide evidence to you of such filing.

(iii) assuming due authorization, execution and delivery by Mexico of each Sub-Authorization required by the Authorization and of the Notes against payment therefor, and assuming due authentication, execution and delivery of the Notes by the Fiscal Agent, the Notes will be the valid, binding and enforceable obligations of Mexico, entitled to the benefits of the Fiscal Agency Agreement, (a) subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and to general principles of equity and (b) subject to possible judicial action giving effect to foreign governmental actions or foreign laws affecting creditors’ rights;

		(iv) the issuance and sale of the Notes by Mexico pursuant to this Agreement and any applicable Terms Agreement and the performance by Mexico of its obligations in this Agreement, the Fiscal Agency Agreement, the Notes and the Authorization do not require any consent, approval, authorization, registration or qualification of or with any governmental authority of the United States or the State of New York that in such counsel’s experience is normally applicable in relation to transactions of the type contemplated by this Agreement, the Fiscal Agency Agreement, the Authorization and the Notes, except such as have been obtained or effected under the Act and such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or Blue Sky laws in connection with the purchase and distribution of the Notes under this Agreement (as to which such counsel need express no opinion);

(b) Mexico agrees that any person who has agreed to purchase and pay for any Note pursuant to a solicitation by any of the Agents shall have the right to refuse to purchase such Note if, subsequent to the agreement to purchase such Note, any change, condition or development specified in Section 9(b)(ii) shall have occurred (with the judgment of the Agent which presented the offer to purchase such Note being substituted for any judgment of a Purchaser required therein) the effect of which is, in the judgment of the Agent which presented the offer to purchase such Note, so material and adverse as to make it impractical or inadvisable to proceed with the sale and delivery of such Note (it being understood that under no circumstance shall any such Agent have any duty or obligation to Mexico or to any such person to exercise the judgment permitted to be exercised under this Section 7(b) and Section 9(b)).

8. Indemnification and Contribution. (a) Mexico agrees to indemnify and hold harmless each of you, the directors, officers, employees and agents of each of you and each person who controls each of you within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which you, they or any of you or them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus, or the Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each such indemnified party for any legal or other expenses, as incurred, reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that (i) Mexico will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to Mexico by any of you specifically for inclusion therein and (ii) such indemnity with respect to any preliminary prospectus or the Prospectus shall not inure to the benefit of any indemnified party from whom the person asserting such loss, claim, damage or liability purchased the Notes which are the subject thereof if such person did not receive a copy of the Prospectus (or an amendment or supplement to the Prospectus) at or prior to the confirmation of the sale of such Notes to such person in any case where such delivery is required by the Act and the untrue statement or omission of a material fact contained in such preliminary prospectus or Prospectus was corrected in the Prospectus (or an amendment or supplement to the Prospectus). This indemnity agreement will be in addition to any liability which Mexico may otherwise have.

Mexico further agrees to indemnify and hold harmless each Agent against any requirement under the laws of Mexico to pay any stamp or similar taxes in connection with any issuance of the Notes to such Agent by Mexico.

(b) Each of you agrees to indemnify and hold harmless Mexico and each of its officials, including its authorized representative in the United States, who signs the Registration Statement to the same extent as the foregoing indemnity from Mexico to you, but only with reference to written information relating to such of you furnished to Mexico by such of you specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which you may otherwise have.

(c) 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 the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, which consent will be not unreasonably withheld. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, Mexico and each of you agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which Mexico and one or more of you may be subject in such proportion as is appropriate to reflect the relative benefits received by Mexico and by each of you from the offering of the Notes from which such Losses arise; provided, however, that in no case shall any of you be responsible for any amount in excess of the commissions received by such of you in connection with the sale of Notes from which such Losses arise (or, in the case of Notes sold pursuant to a Terms Agreement, the aggregate commissions or underwriting discounts payable pursuant thereto). If the allocation provided by the immediately preceding sentence is unavailable for any reason, Mexico and each of you shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of Mexico and of each of you in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by Mexico shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) of the Notes from which such Losses arise, and benefits received by each of you shall be deemed to be equal to the total commissions received by such of you in connection with the sale of Notes from which such Losses arise (or, in the case of Notes sold pursuant to a Terms Agreement, the aggregate commissions or underwriting discounts payable pursuant thereto). Relative fault shall be determined by reference to whether any alleged untrue statement or omission relates to information provided by Mexico or any of you. Mexico and each of you agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls any of you within the meaning of the Act or the Exchange Act and each director, officer, employee and agent of any of you shall have the same rights to contribution as you and each official of Mexico who shall have signed the Registration Statement shall have the same rights to contribution as Mexico, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Termination. (a) This Agreement will continue in effect until terminated as provided in this Section 9. This Agreement may be terminated either by Mexico as to any Agent or by any of you insofar as this Agreement relates to any Agent, by giving written notice of such termination to such Agent or Mexico, as the case may be. This Agreement shall so terminate at the close of business on the first business day following the receipt of such notice by the party to whom such notice is given. In the event of such termination, no party shall have any liability to the other party hereto, except as provided in the fourth paragraph of Section 2(a), Section 4(k), Section 8 and Section 10.

(b) Each Terms Agreement shall be subject to termination in the absolute discretion of the Purchaser, by notice given to Mexico prior to delivery of any payment for any Note to be purchased thereunder, if prior to such time:

(i) In the case of Notes sold pursuant to a Non-U.S. Offering: in the opinion of the Purchaser (or if there is more than one Purchaser, the lead Purchaser), after consultation with Mexico, there shall have been such a change in national or international financial, political or economic conditions or currency exchange rates or exchange controls as would in its view be likely to prejudice materially the success of the offering and distribution of the Notes or dealings in the Notes in the secondary market; or

	(ii) In the case of Notes sold pursuant to all other offerings:

		(A) there shall have occurred, subsequent to the date of such Terms Agreement, any material adverse change in or affecting the financial, economic, political or other condition, or foreign exchange controls, of Mexico otherwise than as set forth in or contemplated by the Prospectus the effect of which is, in the reasonable judgment of the Purchaser, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of such Notes, or there shall have occurred, subsequent to the date of such Terms Agreement, any prospective material adverse change in or affecting the financial, economic, political or other condition, or foreign exchange controls, of Mexico, otherwise than as set forth in or contemplated by the Prospectus, that, in the reasonable judgment of the Purchaser, has had so material and adverse an impact on the market for Mexico’s securities as to make it impractical or inadvisable to proceed with the offering or delivery of such Notes;

		(B) there shall have been, subsequent to the date of such Terms Agreement, (1) any downgrading in the rating accorded Mexico’s debt securities by Standard & Poor’s Corporation or, in the event Standard & Poor’s Corporation is no longer rating the debt securities of Mexico, another nationally recognized statistical rating agency as reasonably agreed upon by Mexico and the Agents or (2) any public announcement that the rating of any of Mexico’s debt securities is under surveillance or review, with possible negative implications, by Standard & Poor’s Corporation or, such other rating agency, as aforesaid, except that if the applicable Terms Agreement so specifies, this Section 9(b)(ii)(B) will not apply;

		(C) trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such Exchange;

(D) trading of any securities of Mexico shall have been formally suspended on any exchange or in any over-the-counter market outside Mexico;

		(E) a general moratorium on commercial banking activities in New York or Mexico shall have been declared by either United States or New York State authorities or authorities of Mexico, respectively;

		(F) a material disruption of the settlement or clearance of debt securities in the United States, Europe or Mexico shall occur and continue until at least the business day preceding the applicable Closing Date, and such event shall make it impractical to proceed with the delivery of such Notes; or

		(G) there shall have occurred any outbreak or escalation of hostilities involving the United States or Mexico or the declaration by the United States or Mexico of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the reasonable judgment of the Purchaser, impracticable or inadvisable to proceed with the offering or delivery of such Notes as contemplated by the Prospectus.

10. Survival of Certain Provisions. The respective agreements, representations, warranties, indemnities and other statements of Mexico or its officers and of you set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of you or Mexico or any of the directors, officers, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Notes. The provisions of Sections 4(k) and 8 hereof shall survive the termination or cancellation of this Agreement. The provisions of this Agreement (including without limitation Section 7 hereof) applicable to any purchase of a Note for which an agreement to purchase exists prior to the termination hereof shall survive any termination of this Agreement. If at the time of termination of this Agreement any Purchaser shall own any Notes with the intention of selling them, the provisions of Section 4 shall remain in effect until such Notes are sold by the Purchaser.

11. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to any of you, will be mailed, delivered or telexed or telecopied and confirmed to such of you, at the address specified in Annex I hereto; or, if sent to Mexico, will be mailed, delivered or telexed or telecopied and confirmed to it at:

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 any of the Notes remain outstanding or, if such person shall not be maintained, Mexico will appoint CT Corporation System to act as its process agent as provided herein.

Service of process upon the Authorized Agent at 00 Xxxx 00xx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, and written notice of such service mailed or delivered to Mexico at its address set forth in Section 11 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 irrevocably waives 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 the Specified Courts or in any competent court in Mexico, except that under Article 4 of the Federal Code of Civil Procedure of Mexico attachment prior to judgment or attachment in aid of execution will not be enforced by Mexican courts against property of Mexico.
