The above opinions are subject to the following qualifications:

1. Enforcement of the Transaction Documents is limited by bankruptcy, concurso mercantil, insolvency, liquidation, reorganization, moratorium, labor, taxand other laws of general application relating to or affecting the obligations of debtors and the rights of creditors. 2. Under Mexican Law, provisions of the Transaction Documents granting discretionary authority to any party thereto cannot be exercised in a manner inconsistent with relevant facts nor defeat any requirements from a competent authority to produce satisfactory ·evidence as to the basis of any determination; in addition, under Mexican law, the parties will have the right to contest in court any notice or certificate purporting to be conclusive and binding. 3. Creditors for the expenses incurred for the management of a bankruptcy estate, creditors for the expenses incurred to cover ordinary protection expenses incurred for the conservation, management and safety of a bankruptcy estate, expenses incurred in connection with any procedure, judicial or extrajudicial, for the benefit of a bankruptcy estate, and the fees of the examiner (visitador), mediator (conciliador) and receiver (sindico), labor claims, claims of tax authorities for unp id Jaxes:: _ocial security quotas, workers' housing fund quotas and retirem nt fl:lfl!:1 fo'.f .s cfpreferred by statute and will have priority over secured, unsecured and supordinaied·2laims. . .. .' .• .. . . - 4. Taking of possession, entry, removal, ai /_:·i sfer or other disposition of property or similar action may not be made in Mexico without the intervention of a judicial or administrative Mexican authority in compliance with due process. 5. Covenants and other agreements to perform an act (other than payment of money), and covenants and other agreements not to perform an act are not specifically enforceable in Mexico, although any breach thereof may give rise to an action for money damages and losses (dafios y perjuicios). 6. Although ICAPI's and CONOISA's obligations to pay in dollars outside of Mexico is valid, it should be noted that pursuant to Article 8 of the Monetary Law (Ley Monetaria) of Mexico, if collection of amounts payable by ICAPI's and CONOISA's in foreign currency outside Mexico under the Transaction Documents is sought in Mexico, Mexican courts might render a judgment in Mexican currency or, if such judgment is rendered in foreign currency but payable in Mexico, such judgment may be dischar_A •.i iZA _ Pesos, at the rate of exchange in effect at the date and place where payment is o.J\t;, t:;;,;,_ /..,_'-rj -':_.it(,; . % determined by the Central Bank of Mexico (Banco de Mexico). 4-l(: .., ..: ..·.;:t--- t,_., ..r.

8. The right to initiate an action may expire under the applicable statutes -of limitations. In addition, Mexican law on statutes of limitations may not be waived and claims may not be enforced after the applicable Mexican statute of limitations period has elapsed or may become subject to defenses or set-off or counter claim. 9. We note that procedural rights cannot be validly waived under Mexican law. 10. We express no opinion as to the irrevocable nature of the powers of attorney granted pursuant to the Transaction Documents by [*] to [*] to act as special attorney -in• fact to fulfill with the obligation described in Section [*] of the Loan Agreement; prov ided that under Article 2596 of the Federal Civil Code it is legally permissible to grant "irrevocable" powers of attorney as a mechanism to comply with a contractual obligation. In any event, under Mexican law, in the case that [*] revokes the respective power of attorney to[*], referred to above, in violation of the Loan Agreement, then[*] may be held responsible for the proved direct losses and damages caused by such action. 11. In an event of concurso mercantil of any of the Entities, unsecured obligations in foreign currency must be converted into Mexican currency at the rate of exchange in force on the date of the respective court's judgment and then converted into Unidades de Inversion (UDIS or inflation indexed units). 12. We note that servib•e 'of roces·s by mail does;not constitute personal service under the laws •?fiMeij .:. efqt /1ft:the.,e'\Zent that 'se ice of process is effected by mail, or in anyfu;tMieGpr ci d··under the Indenture and similar provisions of the other Transaction Documents that does not constitute personal service under the laws of Mexico, a judgment of any court rendered against the Company in respect of a Transaction Document to which it is a party would not be enforced by a court in Mexico. 13. Under Mexican law, each of (i) the extension or the granting of grace periods to a principal obligor, (ii) any modification that would increase any obligation of a guarantor, and (iii) the novation of a principal obligation, requires the consent of each guarantor of the relevant obligation. Therefore, the obligations of any Mexican subsidiary guarantor under the Transaction Documents may not be enforced by Mexican courts in the event that any guaranteed obligations are extended, increased or novated without the relevant subsidiary guarantor's consent. Likewise, under Article 87 of the Mexican Concursos Law, any contractual stipulation which, due to the filing of a Concurso (business reorganization or bankruptcy) petition or demand, or a business reorganization declaration, , . . e sets modifications that worsen the contract terms for a debtor or guarantor shall be not included in the relevant debt instrument. .,'-:! ...:-ir o5 . 1 %'>"'1 .-:1-.- f.. . ,1"7 16 f t ir:; il f 14.

G ( ,5 Disrnno\-\: 15. We note that an obligation to pay interest on interest may not be enforceable in Mexico; provided, however, that Article 363 of the Mexican Commerce Code provides

the following "Article 363.-Accrued and unpaid interest, will not accrue interest. The parties, however, may capitalize them" (Articulo 363.-Los intereses vencidos y no pagados, no devengaran intereses. Los contratantes podran, sin embargo, capitaliarlos". 16. Any provision in the Transaction Documents to the effect that the invalidity or illegality of any part thereof will not inyalidate the remaining obligations may be unenforceable in Mexico to the extent that such invalid or illegal provision constitutes an essential element of the Transaction Documents. · 17. We note that the enforcement of indemnity or contribution provisions set forth in any of the Transaction Documents may be limited by public policy in Mexico. 18. We express no opinion regarding tax or labor matters. 19. We express no opinion in respect of the availability of self-help or other non• judicial remedies under Mexican law. We express no opinion as to any laws other than the laws of Mexico in effect as of the date hereof and we have assumed that there is nothing in any other jurisdiction (other than Mexico) that affects our opinion which is delivered based on the legal provisions as of the date hereof. In particular, we have made no independent investi&atiop of the laws of the United States of America or Luxemburg,.as a b "Si i_;fd-r e i, ioa.),t e<ji erein and do not express or imply any opinion on or based or..'stanclatils-·provided for in such laws. We express no opinion as to the rights, bligations or other matters arising subsequent to the date hereof, and we assume no obligation to advise you, your counsel or any other person or entity of any changes to our opinion subsequent to the date hereof.

1.-En terminos del articulo 1° de la Ley de Concursos Mercantiles (la "LCM"), el concurso mercantil tiene como finalidad conservar las empresas y evitar que su incumplimiento generalizado de las obligaciones de pago ponga en riesgo su viabilidad y de las demas personas con las que mantenga una relaci6n de negocios. 2.-El articulo 87 de la LCM expresamente establece que seran nulos los pactos contractuales que establezcan modificaciones que agraven para el Comerciante los terminos de los contratos, en caso de que se presente una solicitud o demanda de concurso mercan til, o bien se declare al Comerciante en concurso mercantil; lo anterior salvo las excepciones expresamente establecidas en la LCM. 3.-La LCM, en terminos de lo dispuesto por sus articulos 2° y relativos, divide el procedimiento de concurso mercantil en una etapa preliminar y dos etapas concursales, cada una con distintos objetivos, terminos y resoluciones: verificaci6n, conciliaci6n y quiebra. •. •• :,..,......._,.ff•.:.•tt .!··,\;.·· :z..,. ri ,'-·;_,,._ ;"! . :·:.1r ): fv:,; • .-'¥,' ,1,-•1':,' · ,.;J ·'·•, \ • ,,.,•,.

La quiebra tiene como objetivo la venta de la empresa en su totalidad, la venta de sus unidades productivas o la venta de sus bienes individualmente considerados, con el orden de preferencia indicado por la LCM. En cada etapa el Juez tiene un auxiliar propuesto por el Instituto Federal de Especialistas de Concursos Mercantiles ("Ifecom"): (i) Visitador en la etapa preliminar de verificaci6n; (ii) Conciliador en la etapa de conciliaci6n; y (iii) Sindico en la etapa de quiebra. },,1,-.;, /w Los auxiliares se seleccionan al azar en cada procedimiento concursal, a la.J-'· que las partes designen al Conciliador Conforme el articulo 147 de la LCM8 ,.'?fff!. .'..,_: ,. • ·;: :!""

El comerciante y un grupo de acreedores

Los auxiliares del Juez tienen un limite temporal para el logro del objetivo de cada una de las etapas. La etapa preliminar de verificaci6n termina con la sentencia de concurso, en d6nde se declara o no al Comerciante en concurso mercantil. En la etapa de conciliaci6n el Juez dicta la sentencia de reconocimiento, graduaci6n y prelaci6n de creditos (precedida por la lista provisional de acreedores elaborada por el Conciliador, las objeciones que las partes hagan a esta ultima, y la lista definitiva de acreedores tambien elaborada por el Conciliador) y la sentencia que aprueba el convenio concursal o en caso contrario, la que declara la quiebra del Comerciante. La etapa de quiebra finaliza con la sentencia del Juez que declara la terminaci6n del concurso mercantil. 4.-Durante la etapa de conciliaci6n: •Se suspende el pago de los adeudos contraidos por el Comerciante con anterioridad a la declru:aojqii_rfd ;s qncu di cl-cantil, salvo los que sean indispensables para la operaci6n ordirlfili ..itdl'fii""rirripres , i cluido cualquier credito indispensable para mantener la operaci6n ordinaria de la empresa y la'liquidez n Fesaria durante la tramitaci6n del concurso mercantil. . . ·,_ _. .·'' •Se suspende todo mandamiento de embargo o ejecuci6n en contra los bienes o derechos del Comerciante, con excepci6n de ejecuciones de caracter laboral relativas a salarios de los dos afios anteriores al concurso mercantil. •El Comerciante continua con la administraci6n y operaci6n de su empresa, incluso esta obligado a cumplir aquellos contratos necesarios para su operaci6n.
