FIFTH. ECONOMIC RIGHTS. Unless an Event of Default has occurred and continues to occur, and an Event of Default Notice or an Enforcement Request has been delivered to the Administrator and the Executor, each Pledgor may receive any distribution or dividend that corresponds to the Securities. Each Pledgor may also cause such distribution to be contributed to the patrimony of the guaranty trust (as such term is defined as Guaranty Trust Agreement under the Loan Agreement), subject in any case to the agreements made in terms of the Loan Documents, provided that, if at the time the redemption or the dividend or cash distribution with respect to the Securities is paid, an Event of Default has occurred and continues, the Pledgee or the trust to which such rights have been contributed or transferred, as the case may be, shall be entitled to receive any redemption, reimbursement, dividend or distribution in relation to the Securities and to apply the full amount of any such redemption, reimbursement, dividend or distribution to the payment of the Secured Obligations (whether principal, interest or any other payable obligation), in the order and in accordance with the terms under the Loan Agreement.

The Administrator and Executor shall continue to use their best efforts to deliver said amounts in cash until they are delivered to the person to whom they correspond.

SIXTH. CORPORATE RIGHTS. Except as set forth in the following paragraph, the Administrator will exercise the corporate rights derived from the Securities during the term of this Agreement, in accordance with the written instructions received for this purpose from each Pledgor. The expenses arising from the exercise of the aforementioned rights shall be at the each of the Pledgor’s expense, who shall, if applicable, provide the Administrator with sufficient funds at least 48 (forty-eight) hours prior to the term indicated for the exercise thereof.

In order to exercise the right to vote at the meetings of the Company corresponding to the Securities, unless an Event of Default has occurred and continues, or that an Event of Default Notice has been delivered, or an Enforcement Request has been delivered to the Administrator, each Pledgor must request in writing at least 4 (four) Business Days prior to the date of the shareholders' meeting of the Company, the necessary documentation for

each Pledgor and/or any Person appointed by such to personally attend such meetings (including the documentation to be issued by Indeval evidencing that the Securities are deposited in the account of the Administrator). Such request shall be accompanied with a copy of the notice of convocation to the corresponding meeting, containing the order of the day.

In the event that an Event of Default occurred and as long as such event continues, the Pledgee will be the only one to instruct the Administrator on the manner in which the corporate rights corresponding to the Securities will be exercised, and the Pledgee will be released from any responsibility for instructing the Administrator on the manner in which the corporate rights corresponding to the Securities will be exercised. The right to instruct the Administrator with respect to the manner in which the corporate rights shall be exercised in terms of the provisions of this Clause, shall not interrupt the enforcement procedure agreed upon in Clause Eighth, in the event that said procedure has been initiated.

In the event that the Administrator do not receive sufficient resources or do not receive the instructions from each Pledgor or the Pledgee, as the case may be, shall issue its vote in the way it considers convenient, at its sole discretion, without the Administrator having any responsibility for attending or failing to attend the respective meeting or, for the sense of the vote it has issued.

Each Pledgor hereby undertakes to irrevocably appoint the Pledgee as its attorney-in-fact, so that in its name and on its behalf it may exercise Pledgee’s economic and corporate rights over the Securities in the event of an Event of Default Notice under the terms of this Agreement and in the event that corresponding Pledgor no longer exercises its corporate rights, and for such purposes, the each Pledgor agrees to execute before a notary public, a special irrevocable power of attorney in substantially similar terms as the form attached to this Agreement as Exhibit "F" in favor of the Pledgee to be exercised by any of its attorneys-in-fact or officers, to act in its name and on its behalf and to exercise, execute and defend the economic and corporate rights of each Pledgor over the Securities, with all the powers contained in Article 2554 of the Federal Civil Code and the correlative articles of the Civil Codes of the States of the Mexican Republic, with all the powers that require a special or general clause in accordance with the applicable laws, as well as with sufficient powers to enable the Pledgee to defend any and all of the Securities against any claim. Once each Pledgor grants the irrevocable special power of attorney referred to in this subsection, it undertakes to deliver to the Pledgee an original testimony of the public deeds containing mentioned powers.

SEVENTH. AFFIRMATIVE AND NEGATIVE COVENANTS. As long as the Secured Obligations remain to be complied, each Pledgor:

(a) undertakes to execute and deliver the necessary documents and instruments, and to carry out any other action that may be necessary, in the reasonable judgment of the Pledgee, if any, in order to protect the security pledge created under this Agreement and to enable the Pledgee and the Administrator and the Executor to exercise their respective rights under the terms of this Agreement;

b) refrain from disposing of or granting options on the Securities, or creating any lien, restriction or limitation of ownership with respect to any of the Securities, with the exception of the security pledge created by means of this Agreement;

c) refrain from causing, carrying out, or permit any act that affects or reasonably believes may adversely affect the Securities or the rights or resources of the Pledgee and to immediately notify the Pledgee any of such circumstances;

d) defend at its own expense the Securities from and against any action, suit or proceeding brought against the Pledgee, the Administrator or the Executor by any third party, or in connection with the provisions of this Agreement, before any governmental authority, court or arbitrator (whether Mexican or non-Mexican). The Pledgee shall have the right (but not the obligation) and, if applicable, shall instruct the Administrator to defend the Securities pursuant to this Agreement, in the event that each Pledgor fails to make the corresponding defense, in the understanding that each Pledgor shall reimburse the Pledgee, to the Administrator and the Executor for any documented costs and expenses incurred in connection with such defense and the corresponding amount shall form part of the Secured Obligations until they are paid in full;

e) undertakes to deliver to the Pledgee, any type of information that the latter reasonably requests in relation to the Securities and to carry out those procedures and respective authorizations, including, registration in the Security Interests Sole Registry, as applicable in order to create, maintain and preserve the lien of first place and priority created in favor of the Pledgee pursuant to this Agreement; and

f) undertakes to ratify the signatures of this Agreement before a notary public and to submit this Agreement for registration in the Sole Registry of Movable Assets within 2 (two) Business Days from the date of its ratification before a notary public and to deliver to the Secured Creditor evidence of such registration as soon as possible after the date of its registration but in any event within 5 (five) Business Days from the date on which it is submitted for registration in the Sole Registry of Movable Assets.

EIGHTH. APPOINTMENT OF THE EXECUTOR AND EXTRAJUDICIAL ENFORCEMENT PROCEDURE. (a) The Parties hereby agree to designate Monex Casa de Bolsa, S.A. de C.V., Monex Grupo Financiero, as the executor of this Agreement, who in turn, declares its conformity and acceptance of such assignment. In connection with the obligations of the Executor as executor under this Agreement, and exclusively for the purpose of enabling the Administrator and the Executor to comply with their obligations under this Clause Eighth, each Pledgor hereby and by signing this Agreement grants an irrevocable mandate in the nature of a commercial commission pursuant to the terms provided by Articles 273, 274 and other applicable articles of the Commercial Code, unconditional and irrevocable while this Agreement is in force, in favor of the Administrator and the Executor, so that the Administrator and the Executor may carry out any necessary acts on behalf of each Pledgor in accordance with this Agreement, solely and exclusively for the effects and purposes of the enforcement procedure established by Article 204 of the Securities Market Law.

Additionally, and on its behalf, the Administrator and the Executor hereby accept the aforementioned mandate and, therefore, its capacity as agent, in order to exercise it in accordance with the terms conferred.

Each Pledgor undertakes to pay to Monex Casa de Bolsa, S.A. de C.V., Monex Grupo Financiero, for the acceptance and development of the position of Executor the amounts established in Exhibit G.

(b) The Parties agree to the extrajudicial sale of the Securities and authorize and instruct the Administrator and Executor to carry out the sale, in accordance with the terms and conditions set forth in Article 204 of the LMV, as well as in this Agreement and the Administrator to perform all the necessary acts for the effect that the Executor may complete the extrajudicial sale of the Securities.

In the case that an Event of Default, subject to the terms and provisions set forth in the Loan Documents shall occur, without there being any obligation on behalf of the Administrator or the Executor to verify the existence or validity of such Event of Default, the Pledgee, at its sole discretion without interference from the Pledgors, shall request or notify in writing to the Administrator and the Executor (i) that the same Pledgee will maintain property of the Pledged Shares up to the amount of the Secured Obligations without the need for an execution procedure or judicial resolution, and that the amount of the Pledged Shares given in pledge shall be applied to the payment of the Secured Obligations, at their market value, resulting the effect of such application of payment to extinguish the Secured Obligations up to the amount of the market value of the Pledged Shares given in pledge, or (ii) to carry out the extrajudicial sale of the Securities, in accordance with the following procedure.

Upon the occurrence of an Event of Default, the Pledgee shall have the right to deliver, to each Pledgor, with a copy to the Administrator and the Executor, an Event of Default Notice, at the addresses indicated in this Agreement, in order for each Pledgor to, no later than within the Business Day following such notice, exhibit the payment or, as the case may be, to evidence compliance with the Secured Obligation in question, or to present the document evidencing the extension of the term, novation or waiver of the Secured Obligation in question.

On the date on which the Pledgee gives an Event of Default Notice, the Administrator and the Executor shall perform all acts required so that the Securities under the security pledge may be secured.

If each Pledgor does not exhibit the payment, or if applicable, do not evidence compliance, modification, novation or waiver of the Secured Obligation in question within the term of one Business Day mentioned above, the Pledgee, at its sole discretion without interference from the Pledgors, will deliver to the Administrator and the Executor a request or notice (i) that the same Pledgee will maintain property of the Pledged Shares up to the amount of the Secured Obligations without the need for an execution procedure or judicial resolution, and that the amount of the Pledged Shares given in pledge shall be applied to the payment of the Secured Obligations, at their market value, resulting the effect of such application of payment to extinguish the Secured Obligations up to the amount of the market

value of the Pledged Shares given in pledge, or (ii) to proceed with the enforcement (an "Enforcement Request") and proceed with the sale of part or all of the Securities through the Stock Exchange or outside of it, under the terms and conditions included in the corresponding Enforcement Request, including the designation of the brokerage house(s) that, if applicable, are determined for the coordinated execution of the pledged guarantee.

In case of proceeding with the Enforcement Request, the Securities may be offered or sold in one or more acts, according to the instructions received by the Administrator and the Executor from the Pledgee, at any time, after the Pledgee has delivered an Enforcement Request, at the quoted price per share of the Shares on the Stock Exchange (the "Quoted Price”). The Executor shall deliver to the Pledgee, for the benefit of the Secured Creditors, the proceeds from the sale of the Securities, net of all commissions, expenses, costs and documented fees and approved by the Pledgee, which net resources shall be applied in accordance with the terms of the Loan Agreement. If applicable, the remainder, after full payment of the Secured Obligations, both in cash and in Securities, if any, shall be made available to each Pledgor in the corresponding proportions.

Notwithstanding the foregoing, once 20 (twenty) calendar days have elapsed from the date on which the Pledgee has delivered the Enforcement Request to the Administrator and the Executor without having obtained the extrajudicial sale of sufficient Securities to completely cover the Secured Obligations, the Executor (together with the brokerage house(s) that if applicable, are determined by the Pledgee), may carry out the sale (in one or several acts) of the Securities in favor of a bidder or group of bidders at the price offered by them, provided that such sales shall at all times be conducted in accordance with market practices, customs and usages, including without limitation, that the offering of securities be made to multiple bidders, that an independent investment adviser's valuation be conducted to assess the viability of such bids, that reasonable commercial terms be established for the sales and that the bid representing the highest yield be selected at all times taking into consideration all the terms thereof, among others.

In the event that during the term of this Agreement, for any reason, the listing of the Shares on the Stock Exchange is suspended or stopped or, in any way, it is impossible or difficult to determine the Quoted Price for purposes of complying with an Enforcement Request, the Parties agree that for the purposes of the provisions of this Clause, the Executor may carry out the sale of the Securities (in one or several acts) in favor of a bidder or group of bidders at the price offered by them.

Unless otherwise instructed in writing by the Pledgee, the Executor undertakes to maintain the position of sale of the Securities through the Stock Exchange or to carry out and continue the over-the-counter sale efforts, as the case may be, until the sale is carried out in accordance with the terms set forth in this Agreement. During the term of the over-the-counter sale process provided for in this Clause, any amounts obtained from the sale of the Securities shall be delivered by the Executor to the Pledgee, to be applied in the order and according to the terms provided in the Loan Agreement.

For the purposes of the foregoing, each Pledgor, and the Administrator and Executor, as the case may be, undertake to carry out all the acts and procedures that may be necessary or convenient with Indeval, the depositary of the Securities or any other individuals or legal entities, private or governmental, in order to receive in a timely manner the proceeds of the respective sales for the purposes of this Agreement and to carry out the transfer of the Securities that have been sold on the Stock Exchange or in the stock exchange or over-the-counter market in which they are traded, from the Administrator’s or, if applicable, the Executor’s account to the account or accounts of the depositors of the buyers thereof or its trustees.

In connection with the acts set forth in this Clause Eighth, the Administrator and the Executor undertake to act reasonably, but in no event shall the Pledgee, or the Administrator or the Executor be liable for any loss or impairment that may arise with respect to the Securities as a result of acts performed under this Clause Eighth. Additionally, the Administrator and the Executor undertake to act in strict compliance with the provisions of this Agreement, but in no case shall they will be obliged to verify the Pledgee´s ability to exercise its rights under the terms of the Loan Agreement, nor shall they be liable for the exercise by the Pledgee of such rights.

Each Pledgor agrees that the Executor shall only be obliged to carry out the sale of the Securities, either in the Stock Exchange or in the stock market or over-the-counter market in which they are listed, according to the instructions of the Pledgee, without guaranteeing the result of the sale or the price to be obtained therefrom and shall not be liable for the consequences that the same may cause to the Parties. All costs and expenses caused or incurred by the Administrator and the Executor in connection with the performance of its duties under this Agreement (or any proceedings in which it may become involved as a result of the performance of such duties) shall be borne by each Pledgor.

NINTH. INDIVISIBILITY; NO NOVATION. The security pledge constituted under the terms of this Agreement, whether added or substituted, shall be indivisible and shall remain in full force and effect as long as the Secured Obligations remain unresolved. The execution of this Agreement, as well as the creation of the pledge contemplated herein, does not constitute novation, modification, payment or payment in lieu of payment of the Loan Agreement or any of the Secured Obligations.

TENTH. EXPENSES; COMPENSATION. Each Pledgor undertakes to pay all taxes, interest, penalties, fines, surcharges, liabilities and accessories resulting from the execution of this Agreement, and to indemnify the Pledgee, the Administrator and the Executor for any taxes (payable with withholding or otherwise), interest, penalties, fines, surcharges and accessories that may be demanded or payable with respect to the transactions contained in this Agreement, by any tax, civil, administrative or mercantile authority, as well as for all documented fees and expenses related to any controversy between each Pledgor and the Pledgee and/or the Administrator and the Executor. Additionally, the expenses, commissions, taxes and rights arising from the execution and registration of this Agreement, as well as from any modification of the same, including the fees of the legal advisors of the Pledgee, as well as the expenses, fees and costs incurred by the Secured Creditor and the Executor, for the enforcement of the guarantee subject of this Agreement, shall be on the behalf of and at the expense of each Pledgor.

Each Pledgor agrees to hold harmless the Administrator, the Pledgee and the Executor, their officers, advisors, affiliates, directors, employees and attorneys-in-fact, in the event of any claim, proceeding, suit or action against the Administrator, the Pledgee and the Executor, their officers, advisors, affiliates, holdings, shareholders, directors, employees and attorneys-in-fact, by virtue of any of the acts performed by them in connection with this Agreement. Therefore, each Pledgor undertakes to reimburse the Administrator, the Pledgee and the Executor, their officers, advisors, affiliates, holdings, shareholders, advisors, employees and attorneys-in-fact, for any expense or disbursement of any nature (including duly documented expenses related to legal fees) incurred or any damage or harm suffered by them by virtue of any claim, lawsuit, proceeding or action filed in Mexico or abroad, against the Administrator, the Secured Pledgee and the Executor, its officers, advisors, affiliates, counselors, employees and attorneys-in-fact in connection with any of the acts carried out under the terms of this Agreement and that are not the result of willful misconduct or bad faith from them.

Each Pledgor expressly consents, acknowledges and agrees that, with respect to any circumstance relating to or arising out of this Agreement (i) the Pledgee is acting solely in its capacity as “Collateral Agent”, for the benefit of and in compliance with the instructions of the Secured Creditors, and not in its personal capacity, and therefore assumes no personal or direct obligation whatsoever, express or implied, and (ii) the Pledgee has all the necessary powers and legal authority to act on behalf of and for the benefit of the Secured Creditors; provided that with respect to all matters related to this Agreement, the Secured Creditors shall at all times act through the Pledgee.
