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.

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.

(v)     Neither Mexico nor any person acting on its behalf will engage in any directed selling efforts in the United States with respect to Notes which are to be offered and sold pursuant to a Non-U.S. Offering.

(w)      In respect of any Notes which must be redeemed before the first anniversary of the date of their issue, Mexico will issue such Notes only if the following conditions apply (or the Notes can otherwise be issued without contravention of Section 19 of the FSMA): (i) each relevant Agent represents, warrants and agrees in the terms set forth in Section 3(b); and (ii) the redemption value of each such Note is not less than £100,000 (or an amount of equivalent value denominated wholly or partly in a currency other than sterling), and no part of any Note may be transferred unless the redemption value of that part is not less than £100,000 (or such an equivalent amount).

5.     Conditions to the Obligations of the Agents. The obligations of each Agent to solicit offers to purchase the Notes shall be subject to the accuracy of the representations and warranties on the part of Mexico contained herein as of the Execution Date, on the Effective Date, when any supplement to the Prospectus is filed with the Commission and as of each Closing Date, to the accuracy in all material respects of the statements of Mexico made in any certificates pursuant to the provisions hereof, to the performance by Mexico of its obligations hereunder and to the following additional conditions:

a court-appointed translator would have to be approved by such court after the defendant had been given an opportunity for a hearing as to the accuracy of such translation, and proceedings would thereafter be based upon such translation;

(ix)     there is no tax, levy, deduction, charge or withholding imposed by Mexico or any political subdivision thereof either (A) on or by virtue of the execution, delivery or enforcement of this Agreement, the Fiscal Agency Agreement (including the Authorization pursuant thereto), any Terms Agreement or the Notes or (B) on any payment to be made by Mexico hereunder or any payment of principal, premium, if any, or interest, if any, on 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;

(x)     this Agreement, the Fiscal Agency Agreement, the Authorization, any Terms Agreement and the Notes are in proper legal form under the laws of Mexico for the enforcement thereof against Mexico under the laws of Mexico, provided that, in the event any legal proceedings are brought in any court of Mexico, a Spanish translation of the documents required in such proceedings prepared by a court-appointed translator would have to be approved by such court after the defendant had been given an opportunity for a hearing as to the accuracy of such translation, and proceedings would thereafter be based upon such translation; and

(xi)     the information contained in the Prospectus Supplement under the caption “Taxation—Mexican Taxation” fairly summarizes the provisions of Mexican tax law therein described.

(i)     this Agreement and any applicable Terms Agreement have been duly executed and delivered by Mexico;

(ii)     the Fiscal Agency Agreement and the Authorization have been duly executed and delivered by Mexico and, assuming due authorization, execution and delivery of the Fiscal Agency Agreement by the Fiscal Agent, are valid, binding and enforceable obligations of Mexico, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, to general principles of equity (whether considered in a proceeding in equity or at law) and to possible judicial action giving effect to foreign governmental actions or foreign laws affecting creditors’ rights;

(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

(viii)     the description of U.S. Federal tax consequences set forth under the caption “Taxation—United States Federal Taxation” in the Prospectus Supplement, insofar as such description purports to summarize federal laws of the United States referred to thereunder, constitutes a fair summary of the principal U.S. Federal tax consequences of an investment in the Notes.

 (i)     no information has come to such counsel’s attention that causes such counsel to believe that the Registration Statement, at the time it became effective, and the Prospectus, as of the date thereof, were not appropriately responsive in all material respects to the requirements of the Act and the rules and regulations thereunder;

(ii)     no information has come to such counsel’s attention that causes such counsel to believe that the Registration Statement, at the time it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

(iii)     no information has come to such counsel’s attention that causes such counsel to believe that the Prospectus, as of the date thereof and the Execution Date, contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and

(iv)     the Registration Statement is effective under the Act and, to the best of such counsel’s knowledge, no stop order with respect thereto has been issued, or proceeding for that purpose has been instituted or threatened, by the Commission.

(d)     Each Agent shall have received from the Mexican counsel to the Agents, an opinion, dated the Execution Date, in form and substance reasonably satisfactory to the

(e)     Each Agent shall have received from the United States counsel to the Agents, such opinion or opinions, dated the Execution Date, with respect to the issuance and sale of the Notes, the Fiscal Agency Agreement, the Authorization, the Registration Statement, the Prospectus (together with any supplement thereto) and other related matters as the Agents may reasonably require, and Mexico shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters. In rendering such opinion, such United States counsel to the Agents may rely, without independent investigation on its part, as to matters governed by Mexican law upon the opinion of the Fiscal Attorney of the Federation or the Deputy Director General of Legal Procedures of Credit of the Ministry of Finance and Public Credit described in subsection (b) of this Section 5 and the opinion of the Mexican counsel to the Agents described in subsection (d) of this Section 5;

(f)     Mexico shall have furnished to each Agent a certificate, signed by an official named in the Delegation of Authority, dated the Execution Date, to the effect that the signer of such certificate has carefully examined the Registration Statement, the Prospectus, any supplement to the Prospectus and this Agreement and that:

(i)     the representations and warranties of Mexico in this Agreement are true and correct in all material respects on and as of such date with the same effect as if made on such date;

(ii)     Mexico has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied as a condition to the obligation of the Agents to solicit offers to purchase the Notes;

(iv)     since the respective dates as of which information is given in the Prospectus as amended or supplemented there has been no material adverse change in or affecting the financial, economic, political or other condition of Mexico except as set forth in or contemplated by the Registration Statement and the Prospectus.

(g)     An official named in the Delegation of Authority shall have furnished to each Agent a certificate, dated the Execution Date, to the effect that as of its effective date, the Registration Statement and any further amendment thereto made by Mexico prior to the Execution Date did not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading and that, as of their respective dates, the Prospectus and any further amendment or supplement thereto made by Mexico prior to the Execution Date did not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading and that, as of the Execution Date, neither the Registration

(h)     Prior to the Execution Date, Mexico shall have furnished to each Agent such further information, certificates and documents as the Agents may reasonably request and the opinions and certificates mentioned above or elsewhere in this Agreement shall be in all material respects reasonably satisfactory in form and substance to the Agents and counsel for the Agents.

The documents required to be delivered by this Section 5 shall be delivered at the office of the United States counsel to Mexico, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇.

6.     Conditions to the Obligations of a Purchaser. The obligations of a Purchaser to purchase any Notes will be subject to the accuracy of the representations and warranties on the part of Mexico herein as of the date of the related Terms Agreement and as of the Closing Date for such Notes, to the performance and observance by Mexico of all covenants and agreements herein contained on its part to be performed and observed and to the following additional conditions precedent:

(a)     No stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been instituted or threatened;

(b)     In the case of Notes to be resold by the Purchaser at a fixed public offering price or, unless the Terms Agreement otherwise so states, in the case of Notes to be resold by the Purchaser at varying prices as agreed to between Mexico and the Purchaser in a Terms Agreement, the Purchaser shall have received, appropriately updated, (i) the opinion of either the Fiscal Attorney of the Federation or the Deputy Director General of Legal Procedures of Credit of the Ministry of Finance and Public Credit, dated as of the Closing Date, to the effect set forth in Section 5(b), (ii) the opinion of Cleary, Gottlieb, ▇▇▇▇▇ & ▇▇▇▇▇▇▇▇, United States counsel to Mexico, dated as of the Closing Date, to the effect set forth in Section 5(c), (iii) the opinion of Mexican counsel to the Agents, dated as of the Closing Date, to the effect set forth in Section 5(d); (iv) the opinion of United States counsel to the Agents, dated as of the Closing Date, to the effect set forth in Section 5(e); (v) the certificate of an official named in the Delegation of Authority, dated as of the Closing Date, to the effect set forth in Section 5(f); and (vi) the certificate of an official named in the Delegation of Authority, dated as of the Closing Date, to the effect set forth in Section 5(g); and

(c)     Prior to the Closing Date, Mexico shall have furnished to the Purchaser such further information, certificates and documents as the Purchaser may reasonably request.

If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement and the applicable Terms Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement or such Terms Agreement and required to be delivered to the Purchaser pursuant to the terms hereof or thereof (other than any such opinions or certificates delivered to and accepted by the Agents prior to the date of the applicable Terms Agreement) shall not be in all material respects reasonably satisfactory in form and substance to the Purchaser and its counsel, such Terms Agreement and all obligations of the Purchaser thereunder and with respect to the Notes subject thereto may be canceled at, or at any time prior to, the respective Closing Date by the Purchaser. Notice of such cancellation shall be given to Mexico in writing or by telephone or telegraph confirmed in writing.

7.     Right of Person Who Agreed to Purchase to Refuse to Purchase. (a) 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, at the Closing Date therefor, any condition set forth in Sections 5 or 6, except for Sections 6(b) and 6(c), shall not have been satisfied.

(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

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

(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

(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.

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:
