The Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, telegram, facsimile, telex, teletype or telephone message, electronic mail message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel (including counsel to the Borrowers), independent accountants and other experts selected by the Agent. The Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Credit Line document unless it shall first receive such advice or concurrence of the Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of failing to take, taking or continuing to take any such action. As to any matters not expressly provided for in the Credit Line documents, the Agent shall in all cases be fully protected in acting, or in refraining from acting, in accordance with a request or consent of the Lenders.

ii.

For purposes of determining compliance with the conditions specified in this Section, each Lender that has executed this shall be deemed to have consented to, approved, accepted or to be satisfied with, each document or other matter either provided by the Borrowers to such Lender for consent, approval, acceptance or satisfaction, or required thereunder to be consented to or approved by or acceptable or satisfactory to such Lender unless the Agent shall have received notice from such Lender prior to the proposed Closing Date specifying its objection thereto.

(e) Notice of Default. In no case shall the Agent be deemed of having knowledge or notice of the occurrence of any Default or Event of Default, except if the Agent responsible for the administration of this Agreement were to have received written notice from a Lender or the Borrowers referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “Notice of Default”. The Agent will notify the rest of the Lenders of its receipt of any such notice. The Agent shall take such action with respect to such Default or Event of Default before Airbus or any party of the Step-In Agreement, directed by the Lenders in writing in accordance with this agreement; in the understanding however, that unless and until the Agent has received any such written direction, the Agent may (but is not be obligated to) take such action, or refrain from taking such action.

(f) Credit Decision. Each Lender acknowledges that neither the Agent nor any of its Affiliates, officers, directors, employees, agents or attorneys-in-fact have made any representation or warranty to it, and that no act by the Agent hereinafter taken, including any consent to and acceptance of any assignment or any review of the affairs of the Borrowers and its Subsidiaries, shall be deemed to constitute any representation or warranty by the Agent to any Lender as to any matter, including whether the Agent has disclosed material information in its possession. Each Lender represents to the Agent that it has, independently and without reliance upon the Agent and based on such documents and information as it has deemed appropriate, made its own appraisal of an investigation into the business, prospects, operations, property, financial and other condition

and creditworthiness of the Borrowers and its Subsidiaries and all applicable Lender regulatory laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit to the Borrowers hereunder.

Each Lender also represents that it will, independently and without reliance upon the Agent and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action in accordance with this Agreement and the other Credit Line documents, and to make such investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrowers and its Subsidiaries.

Except for notices, reports and Operative Documents expressly herein required to be furnished to the Lenders by the Agent, the Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of the Borrowers or the Joint Obligors which may come into the possession of any of the Agent or any of their Affiliates, officers, directors, employees, agents or attorneys-in-fact.

(g) Indemnification. Whether or not the transactions contemplated hereby are consummated, the Lenders shall indemnify upon demand the Agent and its Affiliates, directors, officers, agents and employees (to the extent not reimbursed by or on behalf of the Borrowers and without limiting the obligation of the Borrowers to do so) and as long as a final and binding resolution has been issued by a competent authority, pro rata, and hold the Agent harmless from and against any and all liabilities derived from his role as Agent, included consequences due to error or omission; provided, however, that no Lender shall be liable for the payment to the Agent of any portion of such Indemnified Liabilities to the extent determined in a final judgment by a court of competent jurisdiction to have resulted from the Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender shall reimburse the Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including Attorney Costs) incurred by the Agent in connection with the preparation, execution, delivery, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Credit Line document, or any document contemplated by or referred to herein, to the extent that the Agent is not reimbursed for such expenses by or on behalf of the Borrowers. The Lenders also agree to reimburse the Agent, in advance, for any documented taxes required to be paid by the Agent pursuant to this Agreement. The undertakings in this Section shall survive the payment of all other Obligations and the resignation or removal of the Agent.

(h) Agent acting on behalf of the Lenders. Santander and Bancomext agree and acknowledge that a consent obtained from both of the Lenders shall be required in order for the Agent to perform any other act or omission which may result in affecting any of the Lenders’ rights under this Agreement, in the understanding that the Agent shall not agree in any modification to the term, amount, rate or any other related to the Credit, without Bancomext’s consent . Consequently, the Lenders hereto acknowledge and agree that any action taken by the Lenders against the Borrower and the Joint Obligors pursuant to this Agreement, shall always be initiated collectively by all of the Lenders, in the understanding that the Agent does not assumes any liability of any nature in connection with such actions.

Santander and Bancomext agree that in the event that the Agent receives any amount derived from an action taken by him, with the unanimous consent of the Lenders, such amounts shall be distributed evenly by Santander and Bancomext in respect to Bancomext’s Portion and Santander’s Portion hereunder.

(i) Agent in its Individual Capacity. Notwithstanding the provisions contained under Section (h) above, Santander and its Affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally engage in any kind of lending, trust, financial advisory, underwriting or other business with the Borrowers and any of the Borrowers’s Affiliates as though Santander was not the Agent hereunder and without notice to or consent of the Lenders. The Lenders acknowledge that, pursuant to such activities, Santander or its Affiliates may receive information regarding the Borrowers or any of its Affiliates (including information that may be subject to confidentiality obligations in favor of the Borrowers or such Affiliate) and acknowledge that the Agent shall be under no obligation to provide such information to them. With respect to the A Tranche Santander’s Portion and the B Tranche Santander’s Portion, Santander shall have the same rights and powers under this Agreement as any other Lender and may exercise such rights and powers as though it were not an Affiliate of the Agent, and the terms “Lender” and “Lenders” include Santander in its individual capacity.

(j) Successor Agent. The Agent may resign upon thirty (30) days’ notice to the Lenders, and the Agent may be removed at any time, upon written notice to the Administrative Agent, with or without cause by the Lenders. If the Agent resigns or is removed in accordance with this Agreement, the Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall be subject to the prior approval of the Borrowers at all times other than during the existence of an Event of Default (which consent of the Borrowers shall not be unreasonably withheld or delayed). If no successor agent is appointed prior to the effective date of the resignation of the relevant existing Agent or the Lenders’ election to remove such existing Agent, then such existing Agent may appoint, after consulting with the Lenders and the Borrowers, a successor agent from among the Lenders. Upon the acceptance of its appointment as the successor agent hereunder, such successor agent shall thereupon succeed to and become vested with all the rights, powers and duties of the retiring Agent, such retiring Administrative Agent’s appointment, powers and duties as Agent shall be terminated, and the term “Agent” shall mean such successor agent. After the Agent’s resignation or removal hereunder as Agent, the provisions of this section shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement. If no successor agent has accepted appointment as Agent by the date which is thirty (30) days following a retiring Agent’s notice of resignation or removal, the retiring Agent’s resignation or removal shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Agent hereunder until such time, if any, as the Lenders appoint a successor agent as provided for above.

SEVENTEENTH.- ASSIGNMENT.- In terms of Article 299 of the General Law of Negotiable Instruments and Credit Operations, each of the Lenders are hereby authorized to assign, discount, endorse, or in any other way negotiate, partially or in whole and even before they become due, the right to collect the Credit herein granted with the previous written consent granted by each Borrower and by the Joint Obligors (in the understanding that such consent may not be unreasonably denied and if a period of 15 (fifteen) Business Days have passed after the request from such Lender without receiving an answer from the Borrower and by the Joint Obligors, it shall be construed as granted by them). Likewise, such Lender may assign, discount, endorse or in any way transfer, totally or partially, their rights pursuant to this Agreement through a notice previously carried out to each Borrower and the Joint Obligors in the following cases: (i) in the case that such assignment takes place in favor of any affiliate of the Lender, and (ii) in favor of any financial institution in case that an Event of Default occurs pursuant to this Agreement.

In the event that the assignment refered to above were made to any person who, by reason of their domicile or any other cause, generated higher or additional tax burdens to each Borrower and/or the Joint Obligors, such additional tax burdens shall be absorbed by the assignee, in the understanding that the Borrowers and Joint Obligors are not required to pay any additional amount.

Notwithstanding the foregoing, the Lenders shall not make assignments to any person related with the Joint Obligors counterparts.

Consequently, any right to use the unspent balance will be similarly limited or restricted, as the case may be. This clause is subject to Article 294 of the General Law of Negotiable Instruments and Credit Operations.

NINETEENTH.- EARLY TERMINATION.- The Lenders may at any terminate the term for the payment of the benefits granted on behalf of the Borrowers and the Total Amount, (including, but not limited to, any amounts due and payable by A Borrower with respect to the A Tranche Amount and by B Borrower in respect with the B Tranche Amount) in addition to any and all interests and other legal amounts accrued thereon, in the understanding, however, that (i) if any Default or Event of Default is caused by the A Borrower, the Lenders may immediately request payment of any and all amounts of principal, interests and other amounts accrued thereon or related payments relating to the A Tranche Amount, considering any and all referred amounts as due and payable; (ii) if any Default or Event of Default is caused by such B Borrower, the Lenders may immediately request payment of any and all amounts or principal, interests and other amounts accrued thereon or related payments relating to the B Tranche Amount, considering any and all referred amounts thereafter as due and payable; and (iii) if any Default or Event of Default is caused by any of the Borrowers and/or Joint Obligors, the Lenders may immediately request payment of any and all amounts or principal, interests and other amounts accrued thereon or related payments under the Total Amount from the Joint Obligors, considering such amounts thereafter as due and payable.
