3. Purchase, Sale and Delivery of Offered Securities. On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Selling Stockholder agrees to sell to the Underwriters, and the Underwriters agree, severally and not jointly, to purchase from the Selling Stockholder, at a purchase price of $[•] per ADS, the respective numbers of shares of Firm Securities set forth opposite the names of the Underwriters in Schedule A hereto. All or any

part of the Firm Securities that the Underwriters may elect to purchase may be delivered in the form of ADSs or Series B Shares at the Underwriter’s election.

The Selling Stockholder will deliver at the office of Shearman & Sterling LLP the Firm Securities to the Representative for the accounts of the Underwriters, against payment of the purchase price in Federal (same day) funds by official bank check or checks or wire transfer to an account at a bank acceptable to CS , at 10:00 A.M., New York time, on March 1, 2006, or at such other time not later than seven full business days thereafter as CS and the Selling Stockholder determine, such time being herein referred to as the “First Closing Date”. For purposes of Rule 15c6-1 under the Securities Exchange Act of 1934 (the “Exchange Act”), the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Offered Securities sold pursuant to the offering.

No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by CS to the Selling Stockholder.

Each time for the delivery of and payment for the Optional Securities, being herein referred to as an “Optional Closing Date”, which may be the First Closing Date (the First Closing Date and each Optional Closing Date, if any, being sometimes referred to as a “Closing Date”), shall be determined by CS but shall be not later than five full business days after written notice of election to purchase Optional Securities is given. The Selling Stockholder will deliver the Optional Securities being purchased on each Optional Closing Date to the Representative for the accounts of the several Underwriters, against payment of the purchase price therefor in Federal (same day) funds by official bank check or checks or wire transfer to an account at a bank acceptable to CS.

(c) The Company will advise CS promptly of any proposal to amend or supplement the initial registration statement, any additional registration statement or the F-6 Registration Statement, as filed, or the related prospectus or the Initial Registration Statement, the Additional Registration Statement (if any) or any Statutory Prospectus and will not effect such amendment or supplementation to which CS reasonably objects; and the Company will also advise CS promptly of the effectiveness of each Registration Statement (if its Effective Time is subsequent to the execution and delivery of this Agreement) and the F-6 Registration Statement and of any amendment or supplementation of a Registration Statement or any Statutory Prospectus and of the institution by the Commission of any stop order proceedings in respect of a Registration Statement or the F-6 Registration Statement and will use its reasonable best efforts to prevent the issuance of any such stop order and to obtain as soon as possible its lifting, if issued.

(d) If, at any time when a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be required to be) delivered under the Act in connection with sales by any Underwriter or dealer, any event occurs as a result of which the Prospectus as then amended or supplemented would include an 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 it is necessary at any time to amend the Prospectus to comply with the Act, the Company and the Selling Stockholder will promptly notify CS of such event and will promptly prepare and file with the Commission, at the expense of the Selling Stockholder, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance, and the Company shall furnish, at the expense of the Selling Stockholder, to the Underwriters and to the dealers (whose names and addresses the Representative shall furnish to the Company) to which the Offered Securities may have been sold by the

Representative on behalf of the Underwriters and to any other dealers upon an Underwriter’s reasonable request, such amendments or supplements to the Prospectus as may be necessary so that the statements in the Prospectus as so amended or supplemented will not, in light of the circumstances when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with any applicable U.S. or Mexican laws. Neither CS’s consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7.

(e) As soon as practicable, but not later than the Availability Date (as defined below), the Company will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the Effective Date of the Initial Registration Statement (or, if later, the Effective Date of the Additional Registration Statement) which will satisfy the provisions of Section 11(a) of the Act.

The Prospectus shall be so furnished on or prior to 3:00 P.M., New York time, on the business day following the later of the execution and delivery of this Agreement or the Effective Time of the Initial Registration Statement. All other documents shall be so furnished as soon as available. The Selling Stockholder will pay the expenses of printing and distributing to the Underwriters all such documents.

(g) The Company will use reasonable efforts to arrange for the qualification of the Offered Securities for sale under the laws of such jurisdictions as CS reasonably requests and will continue to use reasonable efforts to maintain such qualifications in effect so long as required for the distribution of the Offered Securities, provided, that the Company shall not be required to file a general consent to service of process in any jurisdiction other than as specifically required hereunder and under the Deposit Agreement.

(h) All payments to be made by the Company hereunder shall be made without withholding or deduction for or on account of any present or future taxes, duties or governmental charges whatsoever unless the Company is compelled by law to deduct or withhold such taxes, duties or charges. In that event, the Company shall pay such additional amounts as may be necessary in

Mexican currency at the rate of exchange for such currency fixed by Mexico’s central bank (Banco de México) on the date when payment is made);

(J) the court issuing the judgment is considered of competent jurisdiction under the rules internationally accepted that are compatible with Mexican procedural laws; and

(K) the documents relating to the legal action instituted before the foreign court and the judgment rendered thereunder would have to be translated into Spanish by an expert duly authorized by the Mexican courts for their admissibility before the Mexican court before which enforcement is requested (such translation would have to be approved by the Mexican court after the defendant had been given an opportunity to be heard with respect to the accuracy of the translation, and such proceedings would thereafter be based upon the translated documents).

(xxxiii) The Offered Securities may be 100% owned by non-Mexican persons, and any applicable approvals or authorizations required for such foreign ownership have been obtained and are currently in effect.

(xxxiv) The Company is in compliance with any surviving obligation binding upon it pursuant to the Mexican government’s privatization protocols and documents, including but not limited to the General Guidelines for the Opening to Investment in the Mexican Airport System, as published in the Official Gazette of the Federation on February 9, 1998, except for such noncompliance that would not reasonably be expected to have a Material Adverse Effect.

8. Indemnification and Contribution. (a) The Company will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act 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 any material fact contained in any Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus, 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 Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred subject to the limitations set forth in Section 8(c); provided, however, that the Company 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 an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below, provided, however, that the foregoing indemnity provisions with respect to any preliminary prospectus, Prospectus or supplement or amendment thereto shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased ADSs or Shares, or any person controlling such Underwriter, if a copy of the Prospectus or supplement or amendment thereto (if the

Company shall have furnished any such supplement or amendment to such Underwriter prior to the written confirmation of the sale of the ADSs or Shares to such person), was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the ADSs or Shares to such person, and if the Prospectus or supplement or amendment thereto would have cured the defect giving rise to such loss, claim, damage or liability.

(b) Each Underwriter will severally and not jointly indemnify and hold harmless the Company, its directors and officers and each person, if any who controls the Company within the meaning of Section 15 of the Act, against any losses, claims, damages or liabilities to which the Company may become subject, under the Act 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 any material fact contained in any Registration Statement, each Statutory Prospectus, the Prospectus, any Issuer Free Writing Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representative specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred subject to the limitations set forth in Section 8(c), it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the seventh paragraph under the caption “Underwriting” and the information on discretionary sales contained in the eleventh paragraph under the caption “Underwriting”.

(c) Promptly after receipt by an indemnified party under this Section 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 subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and the indemnified party notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (which counsel shall not, except with the consent of the indemnified party, also be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. It is understood that no Indemnifying Person shall, in connection with any proceeding or related proceeding in any jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any one local counsel) for all Indemnified Persons, and that all such reasonable out-of-pocket fees and expenses shall be reimbursed as they are incurred. No Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent, which consent will not be unreasonably withheld, but if settled with such consent or if there be a final judgment for the plaintiff, each Indemnifying Person agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment to the extent provided herein. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for

fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into in good faith by the Indemnified Person more than 45 days after the receipt by such Indemnifying Person of the aforesaid request and (ii) such Indemnifying Person shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such Indemnifying Person shall not have reimbursed such Indemnified Person in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party under such paragraphs shall contribute to the amount paid or payable by such indemnified parties under such paragraphs as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Stockholder on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and/or the Selling Stockholder or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other documented expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer and

director of the Company who has signed a Registration Statement and to each person, if any, who controls the Company within the meaning of the Act.

9. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on either the First or any Optional Closing Date and the aggregate number of shares of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date, CS may make arrangements satisfactory to the Selling Stockholder for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of shares of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to CS and the Selling Stockholder for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholder, except as provided in Section 10 (provided that if such default occurs with respect to Optional Securities after the First Closing Date, this Agreement will not terminate as to the Firm Securities or any Optional Securities purchased prior to such termination). As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Selling Stockholder and their respective officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company, the Selling Stockholder or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 9 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Selling Stockholder shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Company, the Selling Stockholder and the Underwriters pursuant to Section 8 shall remain in effect, and if any Offered Securities have been purchased hereunder the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 or the occurrence of any event specified in clause (iii), (iv), (v), (vi), (vii) or (viii) of Section 7(c), the Selling Stockholder will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.

11. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed to the Representative, Credit Suisse Securities (USA) LLC, Eleven Xxxxxxx Xxxxxx, Xxx Xxxx, XX 00000-0000, Attention: Transactions Advisory Group, or, if sent to the Company, will be delivered personally and confirmed to it at Grupo Aeroportuario del Xxxxxxxx, X.X. de C.V., Av.

13. Representation of Underwriters. The Representative will act for the several Underwriters in connection with the transactions contemplated by this Agreement, and any action under this Agreement taken by the Representative will be binding upon all the Underwriters.

14. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

15. Absence of Fiduciary Relationship. The Company and the Selling Stockholder acknowledge and agree that:

(a) The Representative has been retained solely to act as underwriter in connection with the sale of the Company’s securities and that no fiduciary, advisory or agency relationship between the Company or the Selling Stockholder, on the one hand, and the Representative, on the other, has been created in respect of any of the transactions contemplated by this Agreement, irrespective of whether the Representative has advised or is advising the Company or the Selling Stockholder on other matters;

(b) the price of the securities set forth in this Agreement was established by the Company and the Selling Stockholder following discussions and arms-length negotiations with the Representative and the Company and the Selling Stockholder are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement;

(c) the Company and the Selling Stockholder have been advised that the Representative and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company or the Selling Stockholder and that the Representative has no obligation to disclose such interests and transactions to the Company or the Selling Stockholder by virtue of any fiduciary, advisory or agency relationship; and

(d) the Company and the Selling Stockholder waive, to the fullest extent permitted by law, any claims they may have against the Representative for breach of fiduciary duty or alleged breach of fiduciary duty and agree that the Representative shall have no liability (whether direct or indirect) to the Company or the Selling Stockholder in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

16. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

17. Submission to Jurisdiction and Waiver of Immunity. (a) Each of the parties hereto hereby irrevocably agrees that any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any state or federal court in the Borough of Manhattan, The City of New York, New York, and irrevocably waives, to the fullest extent permissible by

law, any objection which it may now or hereafter have to the laying of venue of any such proceeding and irrevocably submits to the exclusive personal jurisdiction of such courts in any such suit, action or proceeding. Each of the parties hereto hereby irrevocably waives to the fullest extent permitted by applicable law any rights it may have to any other court in any such suit, action or proceeding. Each of the Company and the Selling Stockholder has validly and irrevocably appointed CT Corporation System as their respective authorized agent (“Authorized Agent”) upon which process may be served in any such action arising out of or based on this Agreement or the transactions contemplated hereby which may be instituted in any state or federal court in the Borough of Manhattan, The City of New York, New York, by any Underwriter or by any person who controls any Underwriter. Such appointments shall be irrevocable. Each of the Company and the Selling Stockholder represents and warrants that the Authorized Agent has agreed to act as said agent for service of process, and each of the Company and the Selling Stockholder agrees to take any and all action, including the granting of powers of attorney and the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid.

Each of the Company and the Selling Stockholder hereby irrevocably waives, to the fullest extent permitted by law any immunity to which it or its assets may otherwise be entitled or become entitled (including sovereign immunity and immunity to pre-judgment attachment and execution) in any legal suit, action or proceeding against it arising out of or based on this Agreement or the transactions contemplated hereby which is instituted in any state or federal court in the Borough of Manhattan, The City of New York, New York, or in any competent court in its own corporate domicile.

18. Currency. The obligation of the Company or the Selling Stockholder in respect of any sum due to any Underwriter shall be paid outside of the United Mexican States and, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day, following receipt by such Underwriter of any sum adjudged to be so due in such other currency, on which (and only to the extent that) such Underwriter may in accordance with normal banking procedures purchase United States dollars with such other currency; if the United States dollars so purchased are less than the sum originally due to such Underwriter hereunder, the Company and the Selling Stockholder agree, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter hereunder, such Underwriter agrees to pay to the Company or the Selling Stockholder an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter hereunder.
