To: Copenhagen Airports A/S


		March 29, 2007

Dear Sirs,

		Re: Project Delta / De-merger Letter Agreement

This letter agreement (“De-merger Letter Agreement”) is to confirm certain arrangements between Copenhagen Airports A/S (“CPH”) and Xx. Xxxxxxxx Xxxxx Xxxxx (“FCP” and together with CPH, the “Parties”), according to the following:

WHEREAS, CPH owns 49% and FCP owns 51% (jointly they own 100%) of the shares representing the capital stock of Inversiones y Técnicas Aeroportuarias, S.A. de C.V. (“ITA”).

WHEREAS, FCP has informed CPH of his intention to purchase, either directly or indirectly through any of his affiliates (other than ITA), 42.65% plus one share of the capital stock of Grupo Aeroportuario del Sureste, S.A.B. de C.V. (“ASUR”) through simultaneous public tender offers for Series B shares and/or ADS’ to be made in Mexico and the United States (the satisfaction or waiver of the conditions of the tender offers at expiration of the same shall be deemed “Successful Expiration”, and the settlement of the tender offers shall be deemed “Acquisition Completion”).

WHEREAS, the Parties have entered into unanimous resolutions of even date, approving, inter alia, the conversion of the Series BB shares representing 7.35% of the capital stock of ASUR into Series B shares of ASUR (the “Converted Shares”) in connection with the De-merger (as defined below), and the amendment of the Trust Agreement dated December 18, 1998, with Banco Nacional de Comercio Exterior, S.N.C., as trustee (the “Bancomext Trust”), pursuant to which currently all of the Series BB shares of ASUR are held in such trust.

Based on the foregoing, the Parties agree to the following:


ONE.		DE-MERGER. In case Successful Expiration occurs, the Parties shall take all necessary actions and enter into any necessary agreements and resolutions in order to resolve the de-merger of ITA (the “De-merger”), in substantially the form attached hereto as Exhibit 1 (the “De-merger Resolutions”), whereby a new vehicle will be created (the “SPV”) and 49% of the shares of stock of ASUR owned by ITA, that is the Converted Shares will be conveyed and transferred to the SPV, which will


		be owned 49 % by CPH and 51 % by FCP, whereas all other of ITA’s remaining assets, rights and obligations, including such under the Technical Assistance and Transfer of Technology Agreement dated 18 December 1998 with ASUR and others (the “TSA”), shall remain in ITA and it being agreed that CPH shall not be required, as a result of this De-merger Letter Agreement, to contribute any funds to, guarantee or otherwise ensure the performance of any of the obligations of ITA and SPV.

TWO.		STOCK PURCHASE AGREEMENT. In case Successful Expiration occurs, the Parties shall immediately take any necessary actions to execute an agreement in substantially the form attached hereto as Exhibit 2 (the “SPV SPA”) under which CPH agrees with FCP and his affiliate making the tender offers, to sell (and whereby FCP and said affiliate agrees to buy) its 49% equity participation in SPV, at a cash price (payable in Mexican pesos at closing of the transaction) that would be equal to 49% of the underlying Converted Shares held by SPV multiplied by the tender offer price actually paid for each Series B share and otherwise on terms not more onerous to CPH than the terms for a sale of Series B shares directly under the tender offers. The price per Series B share in ASUR to be paid in the tender offers shall be not less than Mexican pesos $56.00.

THREE.		BANCOMEXT TRUST AMENDMENT. Subject to Successful Expiration, the Parties acknowledge, accept and agree to cause ITA to amend, restate or re-execute the Bancomext Trust, so that under the new form of such agreement the Series BB shares of ASUR held in such trust will be voted in connection with dividend distribution and capital reduction resolutions in the same way as the majority of the ASUR Series B shares vote in any shareholders meeting of ASUR. For such purposes, they shall cause ITA to negotiate and execute any such amendment, restatement or re-execution of the Bancomext Trust, and thereafter to provide the trustee under the Bancomext Trust the appropriate instructions to obtain the necessary proxies in order to vote the Series BB shares of ASUR held in such trust, with respect to the matters referred to in this Section, in the same way as the majority of the ASUR Series B shares vote in any shareholders meeting of ASUR.

FOUR.		DISTRIBUTION POLICY. Subject to Acquisition Completion, the Parties agree that they will take all necessary or desirable actions to ensure that the members of the Board of Directors of ITA and the member of the Board of Directors of ASUR appointed by each of them shall propose and cause ASUR and its subsidiaries from time to time to distribute in each financial year (a) (x) no less than 70% of the net profit after tax and retained earnings available for distribution pursuant to applicable law and in no event more than the amount of Excess Cash (as calculated pursuant to Exhibit 3 hereto) for the year 2007, (y) no less than 80% of such net profit and retained earnings for the year 2008 and (z) 100% of such net profit and retained earnings thereafter plus (b) up to the maximum amount of the remaining Excess Cash whether by means of capital reductions (subject to obtaining the approval from ASUR’s operating committee, board of directors and shareholders, as necessary), or otherwise pursuant to applicable law; it being understood that the Parties also agree that ASUR shall distribute interim and final dividends (the “Distribution Policy”). FCP shall vote, and FCP shall cause any and all of his affiliates to vote, their shares in ASUR so as to implement the Distribution Policy. Unless otherwise agreed with CPH, FCP shall not be entitled to, and shall cause any and all of his affiliates not to,


		make or support or cause any of their appointees, proxy holders, trustees or other to make or support any distribution proposals not in compliance with the Distribution Policy. Failure to comply with this obligation shall constitute a material breach of the ITA Shareholders Agreement, dated as of November 25, 1998 as amended (the “ITA SHA”) by FCP, unless otherwise agreed by the Parties.

FIVE.		ASUR BYLAWS AMENDMENT. The Parties hereby approve, covenant and agree to take any necessary actions to ensure that the Series BB shares owned by ITA through the Bancomext Trust will be voted in the next shareholders meeting of ASUR in order to approve the amendment to the bylaws to be proposed by the Board of Directors of such Company, in order to reduce the required quorum in second and subsequent calls of the extraordinary shareholders’ meetings from 75% to 50%, consistent with Mexican Law and in accordance with the terms of the unanimous shareholders’ resolution of even date in ITA in the understanding that such quorum reductions will be without prejudice to any and all veto rights that the series BB shareholders may have with respect to any such resolutions.

SIX.		CAPEX AND WORKING CAPITAL FACILITY. The Parties hereby covenant and agree that they will approve and will take all necessary actions to ensure that the member of the Board of Directors of ASUR appointed by each of them will approve the Capex and Working Capital Facility to be made available to ASUR in substantially the terms of the document and pursuant to the commitment letter and related term sheet attached hereto as Exhibit 4, in consideration of the fees described in the fee letter previously delivered to the other Party. FCP covenants and agrees (i) that the definitive agreement(s) under which the Capex and Working Capital Facility will be made available to ASUR shall not include the possibility to make upstream loans as permitted payments, irrespective of the contents of section 41 of the term sheet or, alternatively, (ii) to put in place mechanisms that would allow CPH to veto the decisions related to such upstream loans. The Parties further covenant and agree that they will approve and that they will take all necessary actions to ensure that the member of the Board of Directors of ASUR appointed by each of them will approve any refinancing of such Capex and Working Capital Facility, provided such refinancing is presented in equal or more favorable terms to ASUR than the referred Capex and Working Capital Facility and provided that the refinancing is otherwise in accordance with the refinancing policy set forth in Exhibit 5 (the “Refinancing Policy”). Unless otherwise agreed with CPH, FCP shall not be entitled to, and shall cause any and all of his affiliates not to, make or support or cause any of their appointees, proxy holders, trustees or other to make or support any refinancing proposals not in compliance with the Refinancing Policy. Failure to comply with this obligation shall constitute a material breach of the ITA SHA by FCP, unless otherwise agreed by the Parties.

SEVEN.		TERMINATION. FCP intends either himself or through any of his affiliates other than ITA (i) to Launch within the 90 days following the execution of this De-merger Letter Agreement and (ii) to achieve Successful Expiration within 75 days following the date in which Launch occurs under (i) above.

		In case Successful Expiration has not occurred within the earlier of (a) 75 days following the date in which Launch occurs or (b) 165 days following execution of


		this De-merger Letter Agreement, then the Parties’ rights and obligations under this De-merger Letter Agreement shall terminate, unless otherwise agreed by the Parties. Notwithstanding anything to the contrary herein, Sections Seven, Eight, Nine, Eleven and Twelve shall survive termination of this De-merger Letter Agreement.

		For purposes of this De-merger Letter Agreement, “Launch” shall mean the date on which the commencement of the tender offers by FCP or any of its affiliates other than ITA to purchase from public investors the Series B shares and/or ADS’ of ASUR is published in Mexico.

EIGHT.		CONFIDENTIALITY. The tender offers, this De-merger Letter Agreement and the transactions contemplated hereby are strictly confidential. Except as set forth in Sections Eight (a) (b) and (c) below and as is necessary to implement the tender offers and this De-merger Letter Agreement, the Parties shall not disclose the existence and contents of this De-merger Letter Agreement and the fact that any discussions or negotiations with regard to the tender offers and/or this De-merger Letter Agreement have taken place. For purposes of this Section, any information that is or becomes generally available to the public, other than as a result of a breach hereof, shall not be deemed confidential, except with respect to the breaching party.

	a.		No public announcement or circular or disclosure in connection with the existence or subject matter of this De-merger Letter Agreement shall be made or issued by or on behalf of any of the Parties without the prior written approval of the other Party (such approval not to be unreasonably withheld or delayed). If any such public announcement, press release, circular or disclosure is required by law or by any stock exchange or governmental or other regulatory or supervisory body or authority of competent jurisdiction to whose rules the Party making the announcement or disclosure is subject, whether or not having the force of law (the “Announcing Party”), the Announcing Party shall, to the extent legally permitted and possible, inform the other Party that such a situation has arisen and the Announcing Party shall consult with the other Party before any such requirement for a public announcement, press release, circular or disclosure is complied with by the Announcing Party.

	b.		Notwithstanding the foregoing, nothing contained in this Section shall prevent FCP from making all disclosures necessary to submit a board offer letter, apply for all approvals, comply with applicable law or regulations, and make all filings required to commence the tender offers and achieve Acquisition Completion and the de-merger of ITA; including, without limitation, Regulation 13D and Regulation 14D promulgated under the U.S. Securities Exchange Act of 1934, as amended. At the request of CPH, FCP shall: (i) to the extent legally permitted and possible, consult with CPH and provide a copy of the proposed text of such disclosure prior to any disclosure being made and (ii) deliver to CPH a copy of the text of such disclosure after it has been made.

	c.		Notwithstanding the foregoing, CPH may make such disclosures as are required to observe fiduciary duties and other obligations under applicable law and stock exchange rules; including, without limitation, Regulation 13D promulgated under the U.S. Securities Exchange Act of 1934, as amended. CPH shall: (i) to the extent legally permitted and possible, consult with FCP and provide a copy of the proposed

			text of such disclosure prior to any disclosure being made and (ii) deliver to FCP a copy of the text of such disclosure after it has been made.

	d.		CPH acknowledges that it is aware (and that its affiliates and representatives who have been apprised of this De-merger Letter Agreement have been, or upon becoming so apprised will be, advised) of the restrictions imposed by federal and state securities laws of Mexico and the United States on a person possessing material nonpublic information about a company. In this regard, you hereby agree that while you are in possession of material nonpublic information with respect to ASUR, or with respect to the tender offers, you will not purchase or sell any securities of ASUR, or communicate such information to any third party, in violation of any such laws; provided that the foregoing shall not limit any disclosure by the Parties pursuant to the terms of this De-merger Letter Agreement.


NINE.		DANISH SECURITIES TRADING ACT. FCP recognizes that knowledge of CPH’s engagement in this De-merger Letter Agreement, including the exhibits attached hereto, may be or may become insider information about CPH and the shares and other securities issued by CPH, cf. Section 34(2) of the Danish Securities Trading Act (Vaerdipapirhandelsloven), and that, consequently, FCP may be or may become, from time to time, an insider in relation to CPH within the meaning of Chapter 10 of the Danish Securities Trading Act. The responsibility for determining whether at any point in time FCP (and his respective authorized representatives) would be insiders for the purpose of the Danish Securities Trading Act shall rest with FCP, and not with CPH. In such an event FCP will comply with the restrictions and obligations arising therefrom, including the following:

		For as long as FCP has insider information which could be of importance to a transaction concerning securities of CPH, FCP shall abstain from buying or selling or inducing others to buy or sell shares or other securities of CPH in violation of Section 35 of the Danish Securities Trading Act. FCP is aware of and agrees to adhere to Section 36 of the Danish Securities Trading Act, which provides that any person with insider information shall be prohibited from disclosing such information to any other party unless such disclosure is made within the normal course of the exercise of his employment, profession or duties; provided that the foregoing shall not limit any disclosure by the Parties pursuant to the terms of this De-merger Letter Agreement.

		Any FCP’s authorized representatives are subject to these restrictions and obligations.

		The board offer letter to the board of ASUR, shall include specific information to the ASUR board in order for the directors to be aware that they are receiving insider information about CPH and that the rules of the Danish Securities Trading Act referred to above apply to them and to any other person receiving such insider information. FCP shall seek to agree with ASUR that information on the contemplated transactions be disclosed simultaneously by the Parties and ASUR.

TEN.		ADHERENCE BY AFFILIATE. FCP shall cause its affiliate making the tender offers and any subsequent acquirer of the B Shares in ASUR of this affiliate to


		adhere as a party to and be bound by the obligations incumbent on FCP pursuant to Sections Two, Four, Seven, Eight, Nine, Eleven and Twelve.

ELEVEN.		GOVERNING LAW. This De-merger Letter Agreement shall be interpreted insofar as possible in accordance with Mexican law. Should one or more of the provisions of this De-merger Letter Agreement cease to apply or be modified as a result of invalidity, voidability or for any other reason, this shall not affect the validity of the remaining provisions of this De-merger Letter Agreement.

		If one or more of the provisions of this De-merger Letter Agreement are held to be contrary to the rules of Mexican law or the laws of any jurisdiction which cannot be dispensed with by agreement, the Parties agree that the provisions shall be modified and shall apply with such content as may be validly agreed, and such modification shall not affect the validity of the remaining provisions of this De-merger Letter Agreement.

TWELVE.		DISPUTES. In the event of any dispute, the Parties hereto shall make every effort to reach an amicable settlement within a period of twenty-eight (28) days from the date of the dispute. The Parties shall arrange for a personal meeting between the Chairman or Chief Executive Officer of CPH and FCP and if after the meeting and at the expiry of the twenty-eight (28) days, the dispute remains unsettled, the Parties shall then refer the dispute to arbitration in accordance with this Section.

		Any dispute or claim arising out of or in connection with this Letter Agreement or the breach, termination or invalidity thereof, shall be settled in accordance with the Rules of Arbitration of the International Chamber of Commerce (ICC). The arbitration tribunal shall consist of three (3) members. Each Party shall appoint one (1) arbitrator and such arbitrators shall together appoint the third arbitrator, who shall be the Chairman of the tribunal. The Chairman of the arbitration tribunal shall be appointed by ICC, in the event that the arbitrators appointed by the Parties cannot reach an agreement on the nomination of the Chairman within thirty (30) days of their appointment.

		The place of arbitration shall be Geneva, Switzerland.

		All proceedings of the arbitration, including arguments and briefs, shall be conducted in English.

		The arbitration award shall be final and the parties shall comply with the terms of the award.

UNANIMOUS SHAREHOLDERS RESOLUTIONS
___, 2007

THE UNDERSIGNED, being the holders of the shares representing 100% of the capital stock of Inversiones y Técnicas Aeroportuarias, S.A. de C.V. (the “Company” or “ITA”), hereby agree to the following Unanimous Resolutions, through this written agreement and outside a Shareholders’ Meeting, pursuant to the provisions of Article Twentieth of the Company’s by-laws, as well as Article 178 of the General Law on Commercial Companies:

R E S O L U T I O N S

“FIRST. The de-merger of the Company is hereby approved in accordance with the provisions of Article 228 Bis of the General Law on Commercial Companies, as de-merging entity, which, without being liquidated, shall transfer in block part of its assets and capital stock to a new entity resulting from the de-merger to be named , S.A. de C.V. (“SPV-0”). The de-merger will be effected pursuant to the following provisions:

A.		The de-merger will be carried out based on the audited financial statements of the Company dated as of December 31, 2006, which are attached hereto as “Exhibit “A”, the Balance Sheet as of 2007¹, and the Pro-forma Balance Sheet as of 2007 considering the de-merger effects, as well as the Pro-forma Balance Sheet of [SPV-0] S.A. de C.V., as of 2007, all of which are attached hereto as Exhibit “B”. These attachments will be considered integral part of these minutes as if they were reproduced herein.

		The summary of the statements and consolidated balances of reference is the following (amounts expressed in millions of pesos):

	•	Figures of the Company, as of December 31, 2006: Assets $ M.N.; and Capital Stock $ M.N.

	•	Figures of the Company as of ___, 2007: Assets $ M.N.; and Capital Stock $ M.N.

	•	Figures of the Company, as of ___, 2007 immediately after the de-merger: Assets $ M.N.; and Capital Stock $ M.N.


¹		[This is anticipated to be the date of the settlement of the tender offers.]

	•	Figures of ___, S.A. de C.V., considering that the de-merger has taken place on ___, 2007: Assets $ M.N.; and Capital Stock $ M.N.

		The figures of the Pro-forma Balance Sheets will be updated and adjusted, as applicable, to the amounts effectively reflected on the date in which the de-merger is perfected.

B.		As a consequence of the de-merger, [SPV-0] , S.A. de C.V., acting as de-merged entity, will acquire in block, the following part of the assets and capital stock of the Company, under the following terms and conditions:

	1)	22’050,000 Series “B” shares representing 7.35% (seven point thirty five per cent) of the capital stock of ASUR;

	2)	[$ ] M.N. of the Company’s variable capital stock shall also be transferred to SPV-0.

C.		As of this date, the Company has obtained the consent of the totality of its current known creditors to carry out the de-merger approved herein, and therefore (i) such creditors have waived their right to oppose to the de-merger during the 45-day perfection period provided under section V of Article 228 Bis of the General Law on Commercial Companies as per waivers attached hereto as Exhibit D, and (ii) the de-merger resolutions adopted herein will be effective immediately as far as the parties are concerned and shall become binding upon third parties upon recordation of the public deed containing these resolutions in the Public Registry of Commerce of Mexico City.

CPH	98	—	1,263,325	—	1,164,241

Notwithstanding the above, the minimum fixed capital of ITA will not be reduced and considering that the shares representing the capital stock of the Company have no par value, the number of shares representing the total amount of capital stock of ITA will not be reduced despite the transfer of part of the variable portion of the capital stock of ITA by reason of the de-merger.

E.		SPV-0 will be incorporated with: (i) a minimum fixed capital equivalent to [$50,000.00 M.N.], represented by [51] Series “A-1” common shares without par value, owned by FCP and [49] Series “B-1” common shares without par value, owned by CPH; and (ii) a variable portion equivalent to [$ ] represented by [11,245,449] Series “A-2” common shares without par value, owned by FCP and [10,804,451] Series “B-2” common shares without par value, owned by CPH.

		All the shares representing the capital stock of [SPV-0] shall provide its holders the same corporate and economic rights.

F.		[SPV-0] will be governed by its by-laws attached hereto as “Exhibit E”, which are hereby approved.

“THIRD. As a consequence of the foregoing, the Secretary of the Company is hereby authorized and instructed to (i) issue new share certificates reflecting the new amount of the capital stock of the Company and exchange them against existing certificates; (ii) carry out the corresponding entries in the capital variations’ registry book and in the shares’ registry book of the Company reflecting the resolutions adopted herein; and (iii) carry out the corresponding notices to: (y) the National Registry of Foreign Investment within the next 40 days after the date of this resolutions; and (z) the Ministry of Finance and Public Credit or any other governmental agency or entity pursuant to applicable law.”

It is hereby resolved that SPV-0 and the Company shall indemnify and hold each other harmless from any liabilities, expenses, fees or contributions in which they may incur as a consequence of the obligations corresponding or pertaining to the assets hereby transferred to SPV-0 or relating to the assets which have not been effectively transferred, as the case may be.”

COMMITMENT LETTER

Ladies and Gentlemen:

You have advised CGMI (as defined below) that Grupo Aeroportuario del Sureste, S.A.B de C.V. (“Alpha” or the “Borrower”) intends to obtain financing for certain of its working capital and capital expenditure requirements. In connection therewith, Xx. Xxxxxxxx Xxxxx Xxxxx (“France”) desires to obtain a commitment for the Facilities (as defined and as further described below), the proceeds of which will be used to finance certain working capital and capital expenditure and working capital requirements of the Borrower (such transactions, collectively, the “Transactions”).

In connection therewith, Citigroup Global Markets Inc. (“CGMI”), on behalf of Citigroup (as defined below), is pleased to inform France of Citigroup’s commitment to underwrite the entire amount of the up to MXP3,025,000,000 Unsecured Capital Expenditures and Working Capital Facilities (the “Facilities”) and to act as Administrative Agent for the Facilities, subject to the terms and conditions of this letter and the attached Annex I (the “Term Sheet” and, together with this letter, this “Commitment Letter”). For purposes of this Commitment Letter, “Citigroup” means CGMI, Citibank, N.A., Citicorp USA, Inc., Citicorp North America, Inc. and/or any of their affiliates, including, without limitation, Banamex, as may be appropriate to consummate the transactions contemplated herein.

Section 1. Conditions Precedent. Citigroup’s commitment hereunder is subject to the preparation, execution and delivery of mutually acceptable loan documentation incorporating substantially the terms and conditions outlined in this Commitment Letter (the “Operative Documents”) as well as the satisfaction of all conditions hereunder. CGMI’s commitment under this letter is not conditioned upon or subject to Successful Syndication.

Section 2. Commitment Termination. Citigroup’s commitment hereunder will terminate on the earlier of (a) the date the Operative Documents become effective, and (b) one-hundred eighty (180) days from the date hereof.

Section 3. Syndication. Citigroup reserves the right, before or after the execution of the Operative Documents, to syndicate all or a portion of its commitment to one or more other financial institutions (including institutional investors) that will become parties to the Operative Documents pursuant to a syndication to be managed by CGMI (the financial institutions becoming parties to the Operative Documents being collectively referred to herein as the “Lenders”). CGMI will manage all aspects of the syndication in consultation with France and the Borrower, including the timing of all offers to potential Lenders, the determination of the amounts offered to potential Lenders, the acceptance of commitments of the Lenders and the compensation to be provided to the Lenders.

France shall take, and shall use its best efforts to cause the Borrower to take, all action as CGMI may reasonably request to assist CGMI in forming a syndicate acceptable to CGMI. France’s and the Borrower’s assistance in forming such a syndicate shall include but not be limited to (i) making senior management and representatives of France and the Borrower available to participate in information meetings with potential Lenders at such times and places as CGMI may reasonably request; (ii) using France’s and the Borrower’s best efforts to ensure that the syndication efforts benefit from France’s, the Borrower’s and their respective owners’ lending relationships; and (iii) providing CGMI with all information reasonably deemed necessary by it to achieve Successful Syndication (as further defined).

To ensure Successful Syndication of the Facilities, France agrees that until Successful Syndication has occurred, neither the Borrower nor France will, and will not permit any of their respective affiliates to, syndicate or issue, attempt to syndicate or issue, announce or authorize the announcement of the syndication or issuance of, or engage in discussions concerning the syndication or issuance of, any debt facility or debt security (including any renewals thereof), other than the facilities in respect of the acquisition of the capital stock of the Borrower to be provided by CGMI to France, without the prior written consent of CGMI.

Citibank, N.A. will act as the sole Facility Agent for the Facility and CGMI will act as sole syndication agent. No additional agents, co-agents or arrangers will be appointed, or other titles conferred, without the consent of Citigroup.

“Successful Syndication” shall be deemed to have occurred upon the earlier of (i) the date upon which CGMI has reduced its hold position to no more than MXP300,000,000 and (ii) 120 days following Completion.

Section 4. Fees. In addition to the fees described in Annex I, France shall, or shall cause the Borrower to pay the non-refundable fees set forth in the letter agreement dated the date hereof (the “Fee Letter”) between France and Citigroup. The terms of the Fee Letter are an integral part of Citigroup’s commitment hereunder and constitute part of this Commitment Letter for all purposes hereof.

Section 5. Indemnification. France shall indemnify, or shall cause the Borrower to indemnify and hold harmless Citigroup, each Lender and each of their respective affiliates and each of their respective officers, directors, employees, agents, advisors and representatives (each, an “Indemnified Party”) from and against any and all claims, damages, losses, liabilities and expenses (including, without limitation, fees and disbursements of counsel), that may be incurred by or asserted or awarded against any Indemnified Party (including, without limitation, in connection with any investigation, litigation or proceeding or the preparation of a defense in connection therewith), in each case arising out of or in connection with or by reason of this Commitment Letter or the Operative Documents or the transactions contemplated hereby or thereby or any actual or proposed use of the proceeds of the Facilities, except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a

court of competent jurisdiction to have resulted primarily from such Indemnified Party’s bad faith, gross negligence or willful misconduct. In the case of an investigation, litigation or other proceeding to which the indemnity in this paragraph applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by France, the Borrower, any of their respective directors, security holders or creditors, an Indemnified Party or any other person or an Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated hereby are consummated.

No Indemnified Party shall have any liability (whether in contract, tort or otherwise) to France or the Borrower or any of their respective security holders or creditors for or in connection with the transactions contemplated hereby, except to the extent such liability is determined in a final non-appealable judgment by a court of competent jurisdiction to have resulted primarily from such Indemnified Party’s bad faith, gross negligence or willful misconduct. In no event, however, shall any Indemnified Party be liable on any theory of liability for any special, indirect, consequential or punitive damages (including, without limitation, any loss of profits, business or anticipated savings) and France, on behalf of himself, the Borrower, and any person claiming through France or the Borrower, hereby releases and holds harmless each Indemnified Party from all such liability. France acknowledges that information and documents relating to the Facilities and the transactions contemplated hereby and thereby may be transmitted through IntraLinks, the Internet or similar electronic transmission systems. No Indemnified Party shall be liable for any damages arising from the use by unauthorized persons of information or other materials sent through electronic, telecommunications or other information transmission systems that are intercepted by such persons.

The indemnity and reimbursement obligations of the Borrower hereunder shall be in addition to any other liability the Borrower may otherwise have to an Indemnified Party and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Borrower and any Indemnified Party.

Section 6. Costs and Expenses. France shall, or shall cause the Borrower to pay, or reimburse Citigroup on demand for, all reasonable out-of-pocket costs and expenses incurred by Citigroup (whether incurred before or after the date hereof) in connection with the Facilities and the preparation, negotiation, execution and delivery of this Commitment Letter, including, without limitation, the reasonable fees and expenses of New York counsel (i.e., Xxxxxxxx Chance US LLP) and local counsel (i.e., Xxxxxxx, Angoitia, Xxxxxx x Xxxxxxx, S.C.) (in such case, from and after the date of this Commitment Letter), in U.S. Dollars in New York, New York or, at Citigroup’s direction, in the currency and at the place in which such costs or expenses were incurred, regardless of whether any of the transactions contemplated hereby are consummated. France shall, or shall cause the Borrower to pay all costs and expenses of Citigroup (including, without limitation, the reasonable fees and disbursements of counsel) incurred in connection with the enforcement of any of its rights and remedies hereunder. France shall pay or cause the Borrower to pay for the fees and expenses of its professional and other advisors (including any consultants or advisors jointly retained by France and/or the Borrower on the one hand and Citigroup on the other).

Section 7. Confidentiality. By accepting delivery of this Commitment Letter, each of Citigroup and France agrees that this Commitment Letter is for such party’s confidential use only and that neither its existence nor the terms hereof will be disclosed by such party to any person other than the such party’s officers, directors, employees, accountants, attorneys and other advisors, agents and representatives (the “Representatives”), and then only on a confidential and “need to know” basis in connection with the transactions contemplated hereby; provided, however, that either party may make such other public disclosures of the terms and conditions hereof as such party is required by law), in the opinion of such party’s counsel, to make. Notwithstanding any other provision in this Commitment Letter, each party

hereby confirms that each party and such party’s Representatives shall not be limited from disclosing the U.S. tax treatment or U.S. tax structure of the Facility.

Section 8. Representations and Warranties of the Borrower. France represents and warrants, on behalf of himself and the Borrower, that (i) all information that has been or will hereafter be made available to Citigroup, any Lender or any potential Lender by France or the Borrower or any of their representatives in connection with the transactions contemplated hereby is and will be complete and correct in all material respects and does not and will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein not misleading in light of the circumstances under which such statements were or are made, and (ii) all financial projections, if any, that have been or will be prepared by France or the Borrower and made available to Citigroup, any Lender or any potential Lender have been or will be prepared in good faith based upon reasonable assumptions (it being understood that such projections are subject to significant uncertainties and contingencies, many of which are beyond France’s or the Borrower’s control, and that no assurance can be given that the projections will be realized). France hereby agrees that it will, or will cause the Borrower to, supplement the information and projections from time to time until the Operative Documents become effective so that the representations and warranties contained in this paragraph remain correct.

In providing this Commitment Letter, Citigroup is relying on the accuracy of the information furnished to it by or on behalf of France and/or the Borrower and their respective affiliates without independent verification thereof.

Section 9. No Third Party Reliance, Etc. The agreements of Citigroup hereunder and of any Lender that issues a commitment to provide financing under the Facility are made solely for the benefit of France and the Borrower and may not be relied upon or enforced by any other person. Please note that those matters that are not covered or made clear herein are subject to mutual agreement of the parties. Subject to Section 15 below, neither France nor the Borrower may assign or delegate any of its rights or obligations hereunder without Citigroup’s prior written consent. This Commitment Letter may not be amended or modified, or any provision hereof waived, except by a written agreement signed by all parties hereto.

France hereby acknowledges that Citigroup is acting pursuant to a contractual relationship on an arm’s length basis, and the parties hereto do not intend that Citigroup act or be responsible as a fiduciary to the Borrower, its management, stockholders, creditors or any other person. Each of France and Citigroup hereby expressly disclaims any fiduciary relationship and agrees they are each responsible for making their own independent judgments with respect to any transactions entered into between them. France also hereby acknowledges that Citigroup has not advised and is not advising France or the Borrower as to any legal, accounting, regulatory or tax matters, and that France and the Borrower are consulting their own advisors concerning such matters to the extent they deem appropriate.

France acknowledges that Citigroup and/or one or more of its affiliates may provide financing, equity capital, financial advisory and/or other services to parties whose interests may conflict with the Borrower’s or France’s interests. Consistent with Citigroup’s policy to hold in confidence the affairs of its customers, neither Citigroup nor any of its affiliates will furnish confidential information obtained from the Borrower or France to any of Citigroup’s other customers. Furthermore, neither Citigroup nor any of its affiliates will make available to France or the Borrower confidential information that Citigroup obtained or may obtain from any other person.

Section 10. Governing Law, Etc. This Commitment Letter shall be governed by, and construed in accordance with, the law of the State of New York. This Commitment Letter sets forth the entire agreement between the parties with respect to the matters addressed herein and supersedes all prior communications, written or oral, with respect hereto. This Commitment Letter may be executed in any number of counterparts, each of which, when so executed, shall be deemed to be an original and all of which, taken together, shall constitute one and the same Commitment Letter. Delivery of an executed counterpart of a signature page to this Commitment Letter by telecopier shall be as effective as delivery of an original executed counterpart of this Commitment Letter. Sections 3 through 8 and 10 through 13 hereof shall survive the termination of Citigroup’s commitment hereunder. France acknowledges that information and documents relating to the Facility may be transmitted through Intralinks, the internet or similar electronic transmission systems.

Section 11. Taxes; Payments. All payments under this Commitment Letter shall be non-refundable when paid and shall, except as otherwise provided herein, be made in MXP in Mexico and shall be made free and clear of and without deduction for any and all present or future taxes (including VAT), levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto. If France or the Borrower, as the case may be, is required by law to deduct any such taxes, levies, imposts, deductions, charges or withholdings from or in respect of any sum payable to Citigroup, it shall promptly pay the amount deducted to the relevant authorities and France hereby indemnifies Citigroup for any loss, cost, expense or other liability suffered by Citigroup by reason of any failure to make such deductions or make payment to the relevant authorities. The Borrower shall pay any and all such taxes and shall indemnify Citigroup for and hold it harmless against any such taxes and any liability arising therefrom or with respect thereto.

To the fullest extent permitted by law, all payments hereunder shall be made regardless of any defense or counterclaim, including, without limitation, any defense or counterclaim based on any law, rule or policy which is now or hereafter promulgated by any governmental authority or regulatory body and which may adversely affect the Borrower’s obligation to make, or the right of Citigroup to receive, such payments, and such payments shall not be subject to set-off.

The obligation of the Borrower or France, as the case may be, in respect of any sum due from it to Citigroup hereunder shall, notwithstanding any judgment in a currency other than U.S. Dollars, be discharged only to the extent that on the business day following receipt by Citigroup of any sum adjudged to be so due in such other currency Citigroup may in accordance with normal banking procedures purchase U.S. Dollars with such other currency; if the U.S. Dollars so purchased are less than the sum originally due to Citigroup in U.S. Dollars, France agrees, as a separate obligation and notwithstanding any such judgment, to indemnify Citigroup against such loss or shall cause the Borrower to do so, and if the U.S. Dollars so purchased exceed the sum originally due to Citigroup in U.S. dollars, Citigroup agrees to remit to France such excess. Notwithstanding anything contained in this Section 11 and the Fee Letter to the contrary, CGMI will accept payment in MXP of any fees payable in connection herewith or with the Facilities to the extent that such fees relate to advances denominated in MXP.

Section 12. Consent to Jurisdiction, Etc. France hereby irrevocably and unconditionally (i) submits, for himself and his property, to the nonexclusive jurisdiction of any New York State court or Federal court sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Commitment Letter, (ii) agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the extent permitted by law, in such Federal court, (iii) waives, to the fullest extent it may effectively do so, the defense of an inconvenient forum to the maintenance of such action or proceeding, (iv) consents to the

service of any and all process in any such action or proceeding by the mailing of copies of such process to CT Corporation at 000 Xxxxxx Xxxxxx, Xxx Xxxx, XX 00000, Xxxxxx Xxxxxx of America, or in any other manner permitted by applicable law, and (v) agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Commitment Letter will affect Citigroup’s right to serve legal process in any other manner permitted by law or affect Citigroup’s right to bring any action or proceeding relating to this Commitment Letter or the transactions contemplated hereby against the Borrower or its property in the courts of any jurisdiction.

To the extent that France has or hereafter may acquire any immunity from jurisdiction of any court or from set-off or any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to himself or his property, France hereby irrevocably waives such immunity in respect of his obligations under this Commitment Letter.

Section 13. Waiver of Jury Trial. Each party hereto irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this Commitment Letter or the transactions contemplated hereby or the actions of the parties hereto in the negotiation, performance or enforcement hereof.

Section 14. Patriot Act Compliance. CGMI hereby notifies you that pursuant to the requirements of the USA PATRIOT ACT (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies France and the Borrower, which information includes the name and address of France and the Borrower and other information that will allow CGMI to identify France and the Borrower in accordance with the Patriot Act. In that connection, CGMI may also request corporate formation documents, or other forms of identification, to verify information provided.

Section 15. Replacement by Borrower. The parties hereto agree that upon the execution of this letter by Borrower, any and all references to “France” in this letter shall be deemed to be references to “Borrower,” and all rights and obligations of “France” shall be deemed to be assigned to, and shall consist of rights and obligations of, “Borrower.”

Section 16. Non-Duplication. All amounts payable under this Commitment Letter shall be payable without duplication; and to the extent any such amounts are paid by the Borrower, such amounts shall be deemed to satisfy France’s corresponding payment obligations.
