By: -------------------------------------- Name: Title: [SEAL) Attest: -21- SECTION 203. Form of Reverse of Security. This Security is one of a duly authorized issue of Securities of the Company designated as its 125/8% Notes due 2003 (herein called the "Securities"), limited in aggregate principal amount to $250,000,000, issued and to be issued under an Indenture, dated as of July 25, 1996 (herein called the "Indenture"), between the Company and The Chase Manhattan Bank, as Trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. The Securities shall constitute direct, unsecured and unconditional obligations of the Company and will rank pari passu among themselves and with all other present and future unsecured and unsubordinated indebtedness of the Company, other than obligations which are mandatorily preferred by statute or by operation of law. All payments of principal and interest in respect of the Securities shall be made after withholding or deduction for any taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or within Mexico or any authority therein or thereof having power to tax. The Company shall pay such additional amounts ("Additional Amounts") as will result in receipt by the Holders of such amounts as would have been received by them had no such withholding or deduction been required, except that no such Additional Amounts shall be payable with respect to any payment on any Security to the extent: (i) that any such taxes, duties, assessments or other governmental charges would not have been imposed but for a connection between the Holder or beneficial owner of such Security and Mexico (or any authority therein or thereof having power to tax) other than the holding of such Security and the receipt of payments with respect to such Security; (ii) of any such taxes, duties, assessments or other governmental charges with respect to a Security presented for payment more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders, whichever occurs later, except to the extent that the Holder of such Security would have been entitled to such Additional Amounts on presenting such Security for payment on any date during such 30-day period; (iii) of any Mexican taxes to the extent that such Mexican taxes would not have been imposed but for the failure of the Holder or beneficial owner of such Security to comply with any certification, identification, information, documentation or other reporting requirement if (a) such compliance is required by law (including, without limitation, Article 154 of the Mexican Income Tax Law), regulation or administrative practice as a precondition to exemption from, or reduction in the rate of withholding of, Mexican taxes (other than a reduction or exemption pursuant to any income tax treaty to which Mexico is a party) and (b) at least 30 days prior to the first interest payment date with respect to which the Company shall apply this clause (iii), the Company shall have -22- notified the Trustee in writing that the Holders or beneficial Owners of the Securities will be required to provide such information or documentation; (iv) of any Mexican taxes imposed at a rate in excess of 15% if (a) such Holder or beneficial owner has failed to provide on a timely basis, at the reasonable request of the Company (subject to the conditions set forth below), information or documentation concerning such Holder's or beneficial owner's eligibility for benefits under an income tax treaty to which Mexico is a party that is necessary to determine the appropriate rate of deduction or withholding of Mexican taxes under any such treaty and (b) at least thirty 30 days prior to the first Interest Payment Date with respect to which the Company shall make such request, the Company shall have notified the Trustee in writing that the holders or beneficial owners of the Securities will be required to provide such information or documentation; or (v) of estate, inheritance, gift, property or other similar taxes imposed with respect to such Security. Notwithstanding the foregoing, the limitations on the Company's obligation to pay Additional Amounts set forth in clauses (iii) and (iv) above shall not apply if a certification, identification, information, documentation or other reporting requirement described in clause (iii), or the provision of information or documentation described in clause (iv), as the case may be, would be materially more onerous, in form, in procedure or in the substance of information disclosed, to such Holders or beneficial owners (taking into account any relevant differences between U.S. and Mexican law, regulation or administrative practice) than comparable information or other reporting requirements imposed under U.S. tax law, regulation (including proposed regulations) and administrative practice or other reporting requirements imposed as of July 22, 1996 under U.S. tax law, regulation (including proposed regulations) and administrative practice (such as IRS Forms 1001, W-8 and W-9). Notwithstanding the preceding sentence, so long as Rule 252 issued by the Secretaria de Hacienda y Credito Publico (the "Ministry of Finance") published in the Diario Oficial de la Federacion on March 29, 1996 or a substantially similar successor of such rule is in effect, the limitations on the Company's obligation to pay Additional Amounts set forth in Clause (iii) above shall not apply unless (a) the certification, identification, information, documentation or other reporting requirement described in such Clause (iii) is required in order to apply Rule 252 (or a substantially similar successor rule thereto), (b) the Company cannot obtain such certification, identification, information, documentation or other reporting requirement through reasonable diligence and (c) the Company otherwise would meet the requirements for application of Rule 252 (or a substantially similar successor rule thereto). In addition, clauses (iii) and (iv) above shall not be construed to require that a non-Mexican pension or retirement fund or a non-Mexican financial institution or any other Holder register with the Ministry of Finance for the purpose of establishing eligibility for an exemption from Mexican withholding tax or to require that a Holder or beneficial owner certify or provide information concerning whether it is or is not a tax-exempt pension or retirement fund. Upon the Trustee's receipt of timely notification from the Company that the Holders or beneficial owners will be required to provide information or documentation, as described in clause (iii) or (iv) above, the Trustee shall provide such notification to the Holders or -23 beneficial owners, as the case may be. The Company shall, as soon as practicable and in no event later than 30 days following the due date for each payment of Mexican taxes withheld by the Company with respect to the Securities, provide the Trustee with a certified copy of the official receipt evidencing the payment of such taxes. The Trustee shall, for a period of five years following the due date for each payment, maintain in its files each such certified copy received from the Company. The Trustee shall, upon written request by the beneficial owner of a Security or any Paying Agent, provide such owner or Paying Agent with a copy of the certified copy of the receipt provided to the Trustee by the Company regarding the amount of Mexican tax withheld by the Company with respect to the Securities within 30 Business Days following the receipt by the Trustee of such request. All references in this Security to principal or interest in respect of any Security shall be deemed to mean and include all Additional Amounts, if any, payable in respect of such principal or interest, unless the context otherwise requires, and express mention of the payment of Additional Amounts in any provision hereof shall not be construed as excluding reference to Additional Amounts in those provisions hereof where such express mention is not made. All references in this Security to principal in respect of any Security shall be deemed to mean and include any redemption price or purchase price payable in respect of such Security pursuant to any redemption provided for above or pursuant to any Offer to Purchase, and express mention of the payment of any redemption price or purchase price in any provision hereof shall not be construed as excluding reference to any redemption price or purchase price in those provisions hereof where such express reference is not made. In the event that Additional Amounts actually paid with respect to the Securities are based on rates of deduction or withholding of Mexican taxes in excess of the appropriate rate applicable to the Holder or beneficial owner of such Securities, and, as a result thereof, such Holder or beneficial owner is entitled to make a claim for a refund or credit of such excess from Mexican tax authorities, then such Holder or beneficial owner shall, by accepting the Securities, be deemed to have assigned and transferred all right, title and interest to any such claim for a refund or credit of such excess to the Company. However, by making such assignment, the Holder or beneficial owner makes no representation or warranty that the Company will be entitled to receive such claim for a refund or credit and incurs no other obligation with respect thereto. Reference is made to Section 1018 of the Indenture for further provisions with respect to the payment of Additional Amounts. If, as a result of any amendment to, or change in, the laws (or any regulation or rulings thereunder) of Mexico or any political subdivision or taxing authority thereof or therein, or any amendment to or change in an official interpretation or application regarding such laws, regulations or rulings, which amendment, change, application or interpretation becomes effective on or after July 22, 1996, the Company pays or would be obligated for reasons outside its control, and after taking reasonable measures available to it to avoid such obligation, to pay Additional Amounts in respect of any Security pursuant to the terms and conditions thereof in excess of those attributable to the Mexican withholding tax of 15% imposed on interest payments to -24- Holders, then, at the option of the Company, the Securities may be redeemed, as a whole but not in part, at any time, upon giving not less than 30 nor more than 60 days' notice by mail to the Holders (which notice shall be irrevocable), at a Redemption Price equal to the principal amount thereof, together with accrued interest to the Redemption Date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the Interest Payment Date that is on or prior to the Redemption Date) and any Additional Amounts which would otherwise be payable; provided that (i) no such notice of redemption may be given earlier than 90 days prior to the earliest date on which the Company would but for such redemption be obligated to pay such Additional Amounts and (ii) at the time such notice is given, such obligation to pay such Additional Amounts remains in effect. Prior to the publication of any notice of redemption pursuant to this provision, the Company shall deliver to the Trustee (i) an Officers' Certificate stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the condition or conditions precedent to the right of the Company so to redeem have occurred and (ii) an Opinion of Mexican Counsel to the effect that the Company has or shall become obligated to pay such Additional Amounts as a result of such amendment or change. Such notice, once delivered by the Company to the Trustee, shall be irrevocable. The Company shall pay all stamp and similar duties, if any, which may be imposed by Mexico, the United States of America or any other governmental entity or political subdivision therein or thereof or any taxing authority of or in any of the foregoing, with respect to the Indenture or the initial issuance of this Security. Except as specifically provided in this Security or the Indenture, the Company shall not be required to make any payment with respect to any tax, duty, assessment or other governmental charge of whatever nature imposed or levied by any government or any political subdivision or taxing authority thereof or therein. If an Event of Default shall occur and be continuing, the principal of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture. The Indenture provides that, subject to certain conditions, if (i) certain Net Cash Proceeds are available to the Company as a result of an Asset Disposition or (ii) a Change of Control occurs, the Company shall be required to make an Offer to Purchase for all or a specified portion of the Securities. The Indenture contains provisions for defeasance at any time of (i) the entire indebtedness of this Security or (ii) certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth therein. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the -25- time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange therefore or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have any right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given written notice to the Trustee of a continuing Event of Default, the Holders of not less than 25% in principal amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, the Trustee for 60 days after the receipt of such notice, request and offer of indemnity has failed to institute any such proceeding, and no direction inconsistent with such request shall have been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or interest hereon on or after the respective due dates expressed herein. No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in The City of New York, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Security Registrar duly executed by the Holder hereof or an attorney for the Holder duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. The Securities are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities of a different authorized denomination, as requested by the Holder surrendering the same. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. -26- Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. Interest on this Security shall be computed on the basis of a 360-day year of twelve 30-day months. All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture. THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS. OPTION OF HOLDER TO ELECT PURCHASE If you want to elect to have this Security purchased in its entirety by the Company pursuant to Section 1015 or 1016 of the Indenture, check the box: |_| If you want to elect to have only a part of this Security purchased by the Company pursuant to Section 1015 or 1016 of the Indenture, state the amount: $ Dated: Your Signature: ----------------------------- (Sign exactly as name appears on the other side of this Security) SECTION 204. Form of Trustee's Certificate of Authentication. This is one of the Securities referred to in the within-mentioned Indenture. Dated: THE CHASE MANHATTAN BANK, as Trustee By ----------------------------------- Authorized Signatory SECTION 205. Book-Entry Notes. (a) Anything in the other provisions of this Indenture to the contrary notwithstanding, it is intended that the Securities shall be initially represented by one or more registered global notes (the "Global Notes") in an amount equal to the aggregate principal amount of the Securities which shall be deposited with, or on behalf of, -27- The Depository Trust Company, New York, New York (the "Depositary") and registered in the name of the Depositary's nominee. The Global Notes shall be substantially in the form provided in Section 201, with such modifications as may be necessary or desirable to reflect the issuance thereof in global form, and may be transferred, in whole and not in part, only to another nominee of the Depositary or to a successor of the Depositary or its nominee. If a Company Order pursuant to Section 303 has been, or simultaneously is, delivered, any further instructions by the Company with respect to the endorsement or delivery of the Global Notes shall be in writing but need not comply with Section 102 and need not be accompanied by an Opinion of Mexican Counsel or an Opinion of U.S. Counsel. The Global Notes shall bear a legend substantially to The following effect: "Unless this Global Note is presented by an authorized representative of The Depository Trust Company ("DTC"), to the Company or its agent for registration of transfer, exchange or payment, and any Global Note issued is registered in the name of Cede & Co., as nominee of DTC (and any payment hereon is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), any transfer, pledge or other use hereof for value or otherwise by or to any other person is wrongful, inasmuch as the record owner hereof, Cede & Co. (or such other entity as is requested by an authorized representative of DTC), has an interest herein." (b) So long as a nominee of the Depositary is the registered owner of the Global Notes, such nominee will be considered the sole owner and holder of the Securities represented by the Global Notes under this Indenture. Except as provided below, owners of beneficial interests in the Global Notes will not be entitled to have Securities represented by the Global Notes registered in their names, will not receive or be entitled to receive physical delivery of the Securities in certificated form and will not be considered the owners or holders thereof under this Indenture. Neither the Company, the Trustee nor any Underwriter (as defined in the Underwriting Agreement) will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Global Notes, or for maintaining, supervising or reviewing any records relating to such beneficial interests. Principal and interest payments on Notes represented by the Global Notes shall be made to the Depositary's nominee as the registered owner of the Global Notes. Under the terms hereof, the Company and the Trustee shall treat the persons in whose names the Notes are registered as the owners of such Notes for the purpose of receiving payment of principal and interest on such Notes and for all other purposes whatsoever. Therefore, neither the Company nor the Trustee has any direct responsibility or liability for the payment of principal or interest on the Notes to owners of beneficial interests in the Global Notes. (c) If the Depositary is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by the Company within 90 days, the Company shall issue Securities in definitive form in exchange for the Global Notes. In addition, the Company may at any time determine not to have the Securities represented by the Global Notes and, in such event, the Company will issue Securities in definitive form in exchange for the Global Notes representing such Securities. In any such instance, an owner of a beneficial interest -28- in the Global Notes will be entitled to physical delivery in certificated form of Securities equal in principal amount to such beneficial interest and to have such Securities registered in its name. Securities so issued in certificated form will be issued in the denominations and in the form provided in this Indenture. ARTICLE THREE THE SECURITIES SECTION 301. Title and Terms. The aggregate principal amount of Securities which may be authenticated and delivered under this Indenture is limited to $250,000,000, except for Securities authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of, other Securities pursuant to Section 304, 305, 306 or 906, or in connection with an Offer to Purchase pursuant to Section 1015 or 1016. The Securities shall be known and designated as the "125/8% Notes due 2003" of the Company. Their Stated Maturity shall be August 1, 2003, and they shall bear interest at the rate of 126/8% per annum, from July 25, 1996 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, payable semiannually on February 1 and August 1, commencing February 1, 1997, until the principal thereof is paid or made available for payment. The principal of and interest on the Securities shall be payable at the office or agency of the Company in The City of New York maintained for such purpose and at any other office or agency maintained by the Company for such purpose; provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. The Company shall pay Additional Amounts, and the Securities shall be subject to redemption by the Company, as provided in Sections 1018 and 1101. The Securities shall be subject to repurchase by the Company pursuant to an Offer to Purchase as provided in Sections 1015 and 1016. The Securities shall be subject to Defeasance at the option of the Company as provided in Article Twelve. The Securities shall constitute direct, unsecured and unconditional obligations of the Company and will rank pari passu among themselves and with all other present and future unsecured and unsubordinated indebtedness of the Company, other than obligations which are mandatorily preferred by statute or by operation of law. SECTION 302. Denominations. The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 and any integral multiple thereof. -29- SECTION 303. Execution, Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its President or one of its Vice Presidents, under its corporate seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities; and the Trustee in accordance with such Company Order shall authenticate and make such Securities available for delivery as in this Indenture provided and not otherwise. Each Security shall be dated the date of its authentication. No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. SECTION 304. Temporary Securities. Pending the preparation of definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and make available for delivery, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. If temporary Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at any office or agency of the Company designated pursuant to Section 1002, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities the Company shall execute and the Trustee shall authenticate and make available for delivery in exchange therefor a like principal amount of definitive Securities of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities. SECTION 305. Registration of Transfer and Exchange. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 1002 being herein -30- sometimes collectively referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed "Security Registrar" for the purpose of registering Securities and transfers of Securities as herein provided. Upon surrender for registration of transfer of any Security at an office or agency of the Company designated pursuant to Section 1002 for such purpose, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any authorized denominations and of a like aggregate principal amount. At the option of the Holder, Securities may be exchanged for other Securities of any authorized denominations and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Security Registrar duly executed, by the Holder thereof or an attorney for such Holder duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304 or 906 or in accordance with any Offer to Purchase pursuant to Section 1015 or 1016. The Company shall not be required to issue, register the transfer of or exchange any Security after the opening of business 15 days before the day of the mailing of a notice of redemption of Securities under Section 1103. SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding. If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a -31- bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount and bearing a number not contemporaneously outstanding. In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Every new Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. SECTION 307. Payment of Interest; Interest Rights Preserved. Interest on any Security which is payable and is punctually paid or duly provided for on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. Any interest on any Security which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below: (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more -32- than 15 days and not less than 10 days prior to the date of the the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder at the address of such Holder as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). (2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee. Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. SECTION 308. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and (subject to Section 307) interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. SECTION 309. Cancellation. All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any Offer to Purchase pursuant to Section 1015 or 1016 shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall be destroyed unless the Trustee shall have received written instructions from the Company directing it to take other action with respect thereto. SECTION 310. Computation of Interest. Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months. -33- SECTION 311. CUSIP Numbers. The Company in issuing the Securities may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers, either as printed on the Securities or as contained in any notice of a redemption, and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in, or omission of, such numbers. ARTICLE FOUR SATISFACTION AND DISCHARGE SECTION 401. Satisfaction and Discharge of Indenture.

SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an Event of Default occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities may declare the principal of all the Securities to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal shall become immediately due and payable. At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if (1) the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all overdue interest on all Securities, (B) the principal of any Securities which have become due otherwise than by such declaration of acceleration (including any Securities required to have -37- been purchased on the Purchase Date pursuant to an Offer to Purchase made by the Company) and interest thereon at the rate borne by the Securities, (C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate borne by the Securities, and (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, dis- bursements and advances of the Trustee, its agents and counsel; and (2) all Events of Default, other than the nonpayment of the principal of Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. No such rescission shall affect any subsequent default or impair any right consequent thereon. SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if (1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or (2) default is made in the payment of the principal of any Security at the Maturity thereof or, with respect to any Security required to have been purchased pursuant to an Offer to Purchase made by the Company, at the Purchase Date thereof, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and interest, and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and on any overdue interest, at the rate borne by the Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as Trustee of an express trust, may institute judicial proceedings for the collection of the sums so due and unpaid, and may prosecute such proceedings to judgment or final decree, and may enforce the same against the Company and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company, wherever situated. If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. -38- SECTION 504. Trustee May File Proofs of Claim. In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 505. Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. SECTION 506. Application of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: FIRST: To the payment of all amounts due the Trustee under Section 607; and SECOND: To the payment of the amounts then due and unpaid for principal of and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and interest, respectively. SECTION 507. Limitation on Suits. No Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless -39- (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default; (2) the Holders of not less than 25% in principal amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities; it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders. SECTION 508. Unconditional Right of Holders to Receive Principal and Interest. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and (subject to Section 307) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date or in the case of an Offer to Purchase made by the Company and required to be accepted as to such Security, on the Purchase Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. SECTION 509. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. SECTION 510. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. -40- The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. SECTION 511. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. SECTION 512. Control by Holders. The Holders of a majority in principal amount of the Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, provided that (1) such direction shall not be in conflict with any rule of law or with this Indenture; (2) the Trustee need not take any action which might involve it in personal liability or be unjustly prejudicial to the Holders not taking part in such action; and (3) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. SECTION 513. Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Securities may on behalf of the Holders of all the Securities waive any past default hereunder and its consequences, except a default (1) in the payment of the principal of or interest on any Security (including any Security which is required to have been purchased pursuant to an Offer to Purchase which has been made by the Company), or (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security affected. Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. SECTION 514. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this -41- Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Holders or the Trustee. SECTION 515. Waiver of Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. ARTICLE SIX THE TRUSTEE SECTION 601. Certain Duties and Responsibilities. The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. SECTION 602. Notice of Defaults. The Trustee shall give the Holders notice of any default hereunder as and to the extent provided by the Trust Indenture Act; provided, however, that in the case of any default of the character specified in Section 501(5), no such notice to Holders shall be given until at least 30 days after the occurrence thereof. For the purpose of this Section, the term "default" means any event which is, or after notice or lapse of time or both would become, an Event of Default. SECTION 603. Certain Rights of Trustee.

SECTION 604. Not Responsible for Recitals or Issuance of Securities. The recitals contained herein and in the Securities, except the Trustee's certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Company of Securities or the proceeds thereof. SECTION 605. May Hold Securities. The Trustee, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Paying Agent, Security Registrar or such other agent. -43- SECTION 606. Money Held in Trust. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company. SECTION 607. Compensation and Reimbursement. The Company agrees (1) to pay to the Trustee from time to time such compensation as shall be agreed in writing between the Company and the Trustee for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and (3) to indemnify each of the Trustee and any predecessor trustee for, and to hold it harmless against, any and all loss, liability, damage, claim or expense, including taxes (other than taxes based on the income of the Trustee), incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall have a lien prior to the Securities as to all property and funds held by it hereunder for any amount owing to it or any predecessor Trustee pursuant to this Section 607, except with respect to funds held in trust for the benefit of the Holders of particular Securities. When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 501(8) or Section 501(9), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for its services are intended to constitute expenses of administration under any applicable Federal or state bankruptcy, insolvency or other similar law. The provisions of this Section shall survive the termination of this Indenture. SECTION 608. Disqualification: Conflicting Interest. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. SECTION 609. Corporate Trustee Required; Eligibility.

If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of a federal or state supervising or examining authority, then, for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. SECTION 610. Resignation and Removal; Appointment of Successor.

(b) The Trustee may resign at any time by giving written notice thereof to the Company. (c) The Trustee may be removed at any time by Act of the Holders of a majority in principal amount of the Outstanding Securities, delivered to the Trustee and to the Company.

(e) If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of notice of resignation or removal, the Trustee resigning or being removed may petition any court of competent jurisdiction for the appointment of a successor Trustee. (f) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Company, by a Board Resolution, -45- shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. SECTION 611. Acceptance of Appointment by Successor. Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts. No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. SECTION 612. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any Successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. SECTION 613. Preferential Collection of Claims Against Company. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the -46- Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor).

The Company will not permit any Subsidiary of the Company, directly or indirectly, to (i) issue or sell any shares of such Subsidiary's Capital Stock (including options, warrants or other rights to purchase shares of such Capital Stock) except (a) to the Company or a Substantially-Owned Subsidiary of the Company or (b) for fair value, or (ii) Incur any Indebtedness except (a) Indebtedness to the Company or to a Subsidiary of the Company; (b) Non-Recourse Indebtedness if such Subsidiary is a Non-Recourse Subsidiary; (c) Indebtedness Incurred in respect of performance bonds, bankers' acceptances and letters of credit provided in the ordinary course of business, provided that the aggregate principal amount of all Indebtedness Incurred pursuant to this clause (c) and clause (iii) of the second paragraph of Section 1008 and outstanding at any one time does not exceed $10 million; (d) Acquired Indebtedness, provided that at the time of Incurrence thereof the Company could Incur at least $1.00 of Indebtedness under the first paragraph of Section 1008; (e) Indebtedness Incurred (A) under Working Capital Facilities, (B) as Acquired Indebtedness and (C) in respect of purchase money obligations; provided that (i) the aggregate amount of Indebtedness outstanding under this clause (e) shall not exceed $80 million and under clause (B) and (C) of this clause (e) shall not exceed $40 million, and (ii) the aggregate amount outstanding under this clause (e) and under clause (i) of Section 1008 shall not exceed $200 million; (f) Indebtedness Incurred under Currency Agreements and Interest Rate Agreements, provided that, in the case of Currency Agreements that relate to other Indebtedness, such Currency Agreements do not increase the Indebtedness of the Company outstanding at any time other than as a result of fluctuations in foreign currency exchange rates; (g) Indebtedness described in clause (vi) of the definition of the term "Indebtedness" resulting solely from a Lien described in Section 1013(x); or (h) Indebtedness Incurred to renew, extend, refinance or refund Indebtedness outstanding on the Issue Date or Indebtedness Incurred pursuant to clause (c), (d) or (e)(B) above, provided, however, that such Indebtedness does not exceed the principal amount of, and premium, if any, on the Indebtedness being renewed, extended, refinanced or refunded, plus costs and expenses ordinarily and customarily incurred upon such renewal, extension, refinancing or refunding, and provided further that if the Indebtedness being renewed, extended, refinanced or refunded is subordinate in right of payment to the Securities, such Indebtedness must be subordinated in right of payment to the Securities to the same extent. SECTION 1012. Limitation on Transactions with Affiliates. The Company will not, and will not permit any Subsidiary of the Company to, directly or indirectly, enter into, renew or extend any transaction (including, without limitation, the purchase, sale, lease or exchange of property or assets, or the rendering of any service) with any Affiliate of the Company or any Subsidiary of the Company, except (i) upon fair and reasonable terms no less favorable to the Company or such Subsidiary than could be obtained in a comparable arm's-length transaction with a Person that is not such an Affiliate and (ii) if such transaction is in the best interests of the Company or such Subsidiary, provided that with respect to a transaction or series of related transactions involving aggregate payments by the Company or such Subsidiary having a fair market value equal to or in excess of (a) $1 million but less than $5 million, the Board of Directors of the Company approves such transaction or series of transactions and, in its good faith judgment, believes that such transaction or series of transactions complies with clauses (i) and (ii) of this paragraph as evidenced by a Board Resolution and (b) $5 million, (A) the Company receives the written opinion of a firm of investment bankers nationally recognized in the United -58- States that such transaction (or series of transactions) is fair, from a financial point of view, to the Company or such Subsidiary and (B) the Board of Directors of the Company approves such transaction or series of transactions and, in its good faith judgment, believes that such transaction or series of transactions complies with clauses (i) and (ii) of this paragraph, as evidenced by a Board Resolution. The foregoing limitation does not limit, and will not apply to (i) any transaction between the Company and any Substantially-Owned Subsidiary of the Company or between Substantially-Owned Subsidiaries of the Company; (ii) any transaction between the Company or any Subsidiary of the Company and any Person that is an Affiliate of the Company or of any Subsidiary of the Company, if (u) such Person is engaged in a similar business to that of the Company and its Subsidiaries, (v) such transaction is in the ordinary course of business of the Company or its Subsidiary, as the case may be, and such Person, (w) such transaction is on fair and reasonable terms no less favorable to the Company or such Subsidiary than could be obtained in a comparable arm's-length transaction with a Person that is not an Affiliate, (x) such transaction is in the best interest of the Company or such Subsidiary, and (y) such Person is an Affiliate solely by virtue of being directly or indirectly controlled by the Company or a Subsidiary of the Company; (iii) payments not prohibited by Section 1009 solely by virtue of clause (iv) of the first paragraph thereof or payments that are "Restricted Payments" not prohibited by Section 1009; (iv) payments of reasonable and customary fees and salaries of directors and officers of the Company; (v) so long as the 1994 Yankee Bonds are outstanding, loans or advances, or transfers of any property or assets to the Company or any Subsidiary of the Company; and (vi) the contribution by the Company of Series A Shares of the Company to the Company's Employee Stock Option Trust. SECTION 1013. Limitation on Liens. The Company will not, and will not permit any Subsidiary of the Company to, Incur any Lien upon property or assets of the Company or any Subsidiary of the Company to secure Indebtedness without making, or causing such Subsidiary to make, effective provision for securing the Securities equally and ratably with (or prior to) such Indebtedness as to such property for as long as such Indebtedness will be so secured unless such Indebtedness is subordinate in right of payment to the Securities, in which case the Securities will be secured prior to such Indebtedness as to such property for as long as such Indebtedness will be so secured. The foregoing restrictions will not apply to (i) Liens existing on the Issue Date; (ii) Liens securing only the Securities; (iii) Liens upon property or assets of any Subsidiary of the Company in favor of only the Company or any Subsidiary of the Company, and Liens upon the property or assets of the Company in favor of only any Substantially-Owned Subsidiary of the Company; (iv) Liens for taxes or assessments or other governmental charges or levies not yet delinquent or, if due, which are being contested in good faith and for which a reserve or other appropriate provision, if any, is being maintained in accordance with Mexican GAAP; (v) Liens Incurred or deposits made in the ordinary course of business to secure obligations under workers' compensation, unemployment insurance and other types of social security laws; (vi) any judgment Lien, unless the judgment it secures will not, within 60 days after the entry thereof, have been discharged or execution thereof stayed pending appeal, or will not have been discharged within 60 days after the expiration of any such stay; (vii) Liens Incurred to secure the performance of -59- statutory obligations, surety or appeal bonds, performance or return-of-money bonds or other obligations of a like nature incurred in the ordinary course of business; (viii) statutory Liens of landlords and Liens of carriers, warehousemen, mechanics, materialmen, repairmen or other similar Liens arising in the ordinary course of business and with respect to amounts not yet delinquent or being contested in good faith by appropriate legal proceedings promptly instituted and diligently conducted and for which a reserve or other appropriate provision, if any, as shall be required in conformity with Mexican GAAP shall have been made; (ix) Liens with respect to Acquired Indebtedness, provided that such Liens do not extend to or cover any property or assets of the Company or any Subsidiary of the Company other than the property or assets acquired and such Acquired Indebtedness is otherwise permitted by this Indenture and such Lien is not incurred in connection with, or in contemplation of, the transaction involving the incurrence of such Acquired Indebtedness; (x) Liens upon property acquired after the Issue Date, provided that (A) such Lien is created solely for the purpose of securing Indebtedness Incurred (1) to finance the cost (including the cost of improvement or construction) of the property subject thereto and such Lien is created prior to, at the time of or within six months after the later of the acquisition, completion of construction or the commencement of full operation of such property or (2) to refinance any Indebtedness previously so secured, (B) the principal amount of the Indebtedness secured by such Lien does not exceed 100% of such cost, (C) any such Lien shall not extend to or cover any property other than such property, the proceeds thereof and any improvements thereon and (D) the Incurrence of the Indebtedness secured by such Lien is otherwise permitted by the Indenture; (xi) Liens securing Indebtedness Incurred under Section 1011(ii)(e)(A); and (xii) Liens securing Indebtedness Incurred to renew, extend, refinance or refund, in whole or in part, Indebtedness secured by any Lien incurred under clause (i), (ix) or (x) hereof, provided, that such Lien does not extend to any other property or assets and the principal amount of Indebtedness so secured is not increased. In addition to the foregoing, the Company and its Subsidiaries may Incur a Lien to secure any Indebtedness, without equally and ratably securing the Securities, if the sum of (i) the amount of Indebtedness secured by a Lien entered into after the date of this Indenture and otherwise prohibited by this Indenture and (ii) the aggregate amount of all Attributable Indebtedness with respect to all Sale and Leaseback Transactions entered into after the date of the Indenture pursuant to Section 1014 does not exceed 15% of the Consolidated Tangible Net Worth of the Company. SECTION 1014. Limitation on Sale and Leaseback Transactions. The Company will not, and will not permit any Subsidiary of the Company to, enter into any Sale and Leaseback Transaction unless the aggregate amount of all Attributable Indebtedness with respect to all such transactions, plus all Indebtedness secured by Liens (excluding secured Indebtedness that is excluded as described in the second paragraph of Section 1013), does not exceed 15% of the Consolidated Tangible Net Worth of the Company. SECTION 1015. Limitation on Asset Sales. In the event and to the extent that the Net Cash Proceeds received by the Company or any of its Subsidiaries from one or more Asset Sales occurring on or after the Issue Date in any period of 12 consecutive months exceed 10% of Adjusted Consolidated Assets in any one fiscal year (determined as of the date closest to the commencement of such 12-month period for which a balance sheet of the Company and its -60- Subsidiaries has been prepared), then the Company will, within 12 months after the date such Net Cash Proceeds are received, apply an amount equal to the Net Cash Proceeds from such Asset Sale (or enter into a definitive agreement committing to so apply such amount within 12 months after the date of such agreement), either (i) to an investment or investments in property or assets that are of a nature or type or are used in a business (or in a company having property and assets of a nature or type, or engaged in a business) similar or related to the nature or type of the property and assets of, or the business of, the Company and its Subsidiaries existing on the date thereof (as determined in good faith by the Board of Directors, whose determination will be conclusive and evidenced by a Board Resolution), or (b) to permanently repay all or a portion of the 1994 Yankee Bonds. The amount of such excess Net Cash Proceeds required to be applied (or to be committed to be applied) during such 12-month period and not applied as so required by the end of such period will constitute "Excess Proceeds." If, as of the first day of any calendar month, the aggregate amount of Excess Proceeds not theretofore subject to an Offer to Purchase totals at least $5 million, the Company must, not later than the fifteenth Business Day of such month, make an Offer to Purchase from the Holders on a pro rata basis an aggregate principal amount of Securities equal to the Excess Proceeds on such date, at a purchase price equal to 100% of the principal amount of such Securities, plus, in each case, accrued interest (if any) to the Purchase Date (subject to the right of Holders of record on the relevant Record Date to receive interest due on an Interest Payment Date that is on or prior to the Purchase Date) (the "Excess Proceeds Payment"). Notwithstanding the foregoing, (i) to the extent that any or all of the Net Cash Proceeds of any Asset Sale are prohibited or delayed by applicable local law from being repatriated to Mexico, the portion of such Net Cash Proceeds so affected will not be required to be applied pursuant to this Section 1015 but may be retained for so long, but only for so long, as the applicable local law will not permit repatriation to Mexico (the Company hereby agrees to promptly take all reasonable actions required by applicable local law to permit such repatriation) and once such repatriation of any such affected Net Cash Proceeds is permitted under the applicable local law, such repatriation will be immediately effected and such repatriated Net Cash Proceeds will be applied in the manner set forth in this Section 1015 as if such Asset Sale had occurred on the date of repatriation; and (ii) to the extent that the Board of Directors has determined in good faith that repatriation of any or all of the Net Cash Proceeds would have an adverse tax consequence to the Company, the Net Cash Proceeds so affected may be retained outside Mexico for so long as such adverse tax consequence would continue. On the Purchase Date the Company will (i) accept for payment on a pro rata basis Securities or portions thereof tendered pursuant to the Offer to Purchase; (ii) deposit with the Paying Agent money sufficient to pay the Purchase Price of all Securities or portions thereof so accepted; and (iii) deliver, or cause to be delivered, to the Trustee Securities or portions thereof so accepted together with an Officers' Certificate specifying the Securities or portions thereof accepted for payment by the Company. The Paying Agent shall promptly mail or deliver to the Holders of Securities so accepted payment in an amount equal to the Purchase Price, and the Trustee shall promptly authenticate and mail or deliver to such Holders a new Security or Securities equal in principal amount to any unpurchased portion of the Security surrendered as requested by the Holder. The Company will publicly announce the results of the Offer to -61- Purchase as soon as practicable after the Purchase Date. For purposes of this Section 1015, the Trustee will act as the Paying Agent. SECTION 1016. Change of Control. (a) Upon the occurrence of a Change of Control, each Holder of a Security shall have the right to have such Security repurchased by the Company on the terms and conditions set forth in this Section 1016 and this Indenture. The Company shall, within 30 days following the date of the consummation of a transaction resulting in a Change of Control (as defined below), make an Offer to Purchase all Outstanding Securities at a Purchase Price equal to 101% of their aggregate principal amount plus accrued interest, if any, to the Purchase Date (subject to the right of Holders of record on the relevant Record Date to receive interest due on an Interest Payment Date that is on or prior to the Purchase Date). (b) One Business Day prior to the Purchase Date, the Company shall deposit with the Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) money sufficient to pay the Purchase Price of all Securities or portions thereof so accepted. On the Purchase Date, the Company shall (i) accept for payment Securities or portions thereof tendered pursuant to the Offer to Purchase, and (ii) deliver, or cause to be delivered, to the Trustee all Securities, or portions thereof so accepted together with an Officers' Certificate specifying the Securities or portions thereof accepted for payment by the Company. The Paying Agent shall promptly mail or deliver to the Holders of Securities so accepted payment in an amount equal to the Purchase Price, and the Trustee shall promptly authenticate and mail or deliver to such Holders a new Security or Securities equal in principal amount to any unpurchased portion of the Security surrendered as requested by the Holder. The Company shall publicly announce the results of the Offer to Purchase on or as soon as practicable after the Purchase Date. (c) A "Change of Control" will be deemed to have occurred in the event that, after the date of this Indenture, either (i)(a) a Person or any Persons acting together which would constitute a "group" (a "Group") for purposes of Section 13(d) of the Exchange Act, or any successor provision thereto, together with any Affiliates or Related Persons thereof (other than any person or Group controlled by the Management Stockholders together with any Affiliates or Related Persons thereof), has become the beneficial owner (other than through the CPO Trust), by way of purchase, merger, consolidation or otherwise, of 35% or more of the Voting Stock of the Company and (b) such Person or Group (together with any Affiliates or Related Persons thereof) has become the beneficial owner (other than through the CPO Trust), by way of purchase, merger, consolidation or otherwise of a greater percentage of Voting Stock of the Company than that held by the Management Stockholders (together with any Affiliates or Related Persons thereof); or (ii) at any time during any consecutive two-year period individuals who at the beginning of such period were members of the Board of Directors of the Company (together with any new directors whose election by such Board of Directors or whose nomination for election by the shareholders of the Company was approved by a vote of a majority of directors then still in office who either were directors at the beginning of such period or whose election or nomination for election was previously so approved) cease for any reason to constitute a majority of the Board of Directors of the Company then in office. -62- SECTION 1017. Indemnification of Judgment Currency. The Company shall indemnify the Trustee and any Holder of a Security against any loss incurred by the Trustee or such Holder, as the case may be, as a result of any judgment or order being given or made for any amount due under this Indenture or such Security and being expressed and paid in a currency (the "Judgment Currency") other than United States dollars, and as a result of any variation between (i) the rate of exchange at which the United States dollar amount is converted into the Judgment Currency for the purpose of such judgment or order and (ii) the spot rate of exchange in The City of New York at which the Trustee or such Holder, as the case may be, on the date of payment of such judgment or order is able to purchase United States dollars with the amount of the Judgment Currency actually received by the Trustee or such Holder. The foregoing indemnity shall constitute a separate and independent obligation of the Company and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term "spot rate of exchange" shall include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, United States dollars. SECTION 1018. Payment of Additional Amounts. (a) All payments of principal and interest in respect of the Securities shall be made after withholding or deduction for any taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or within Mexico or any authority therein or thereof having power to tax. The Company shall pay such additional amounts ("Additional Amounts") as will result in receipt by the Holders of such amounts as would have been received by them had no such withholding or deduction been required, except that no such Additional Amounts shall be payable with respect to any payment on any Security to the extent: (i) that any such taxes, duties, assessments or other governmental charges would not have been imposed but for a connection between the Holder or beneficial owner of such Security and Mexico (or any authority therein or thereof having power to tax) other than the holding of such Security and the receipt of payments with respect to such Security; (ii) of any such taxes, duties, assessments or other governmental charges with respect to a Security presented for payment more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders, whichever occurs later, except to the extent that the Holder of such Security would have been entitled to such Additional Amounts on presenting such Security for payment on any date during such 30-day period; (iii) of any Mexican taxes to the extent that such Mexican taxes would not have been imposed but for the failure of the Holder or beneficial owner of such Security to comply with any certification, identification, information, documentation or other reporting requirement if (a) such compliance is required by law (including, without limitation, Article 154 of the Mexican Income Tax Law), regulation or administrative practice as a precondition to exemption from, or reduction in the rate of withholding of, Mexican taxes (other than a reduction or exemption pursuant to any income tax treaty to which Mexico is a party) and (b) at least 30 days prior to the first interest payment date with respect to which the Company shall apply this clause (iii), the Company shall have -63- notified the Trustee in writing that the Holders or beneficial owners of the Securities will be required to provide such information or documentation; (iv) of any Mexican taxes imposed at a rate in excess of 15% if (a) such Holder or beneficial owner has failed to provide on a timely basis, at the reasonable request of the Company (subject to the conditions set forth below), information or documentation concerning such Holder's or beneficial owner's eligibility for benefits under an income tax treaty to which Mexico is a party that is necessary to determine the appropriate rate of deduction or withholding of Mexican taxes under any such treaty and (b) at least 30 days prior to the first Interest Payment Date with respect to which the Company shall make such request, the Company shall have notified the Trustee in writing that the Holders or beneficial owners of the Securities will be required to provide such information or documentation; or (v) of estate, inheritance, gift, property or other similar taxes imposed with respect to such Security. Notwithstanding the foregoing, the limitations on the Company's obligation to pay Additional Amounts set forth in Section 1018(a)(iii) and 1018(a)(iv) above shall not apply if a certification, identification, information, documentation or other reporting requirement described in Section 1018(a)(iii), or the provision of information or documentation described in Section 1018(a)(iv), as the case may be, would be materially more onerous, in form, in procedure or in the substance of information disclosed, to such Holders or beneficial owners (taking into account any relevant differences between U.S. and Mexican law, regulation or administrative practice) than comparable information or other reporting requirements imposed under U.S. tax law, regulation (including proposed regulations) and administrative practice or other reporting requirements imposed as of July 22, 1996 under U.S. tax law, regulation (including proposed regulations) and administrative practice (such as IRS Forms 1001, W-8 and W-9). Notwithstanding the preceding sentence, so long as Rule 252 issued by the Secretaria de Hacienda y Credito Publico (the "Ministry of Finance") published in the Diario Oficial de la Federacion on March 29, 1996 or a substantially similar successor of such rule is in effect, the limitations on the Company's obligation to pay Additional Amounts set forth in Section 1018(a)(iii) above shall not apply unless (a) the certification, identification, information, documentation or other reporting requirement described in such Section 1018(a)(iii) is required in order to apply Rule 252 (or a substantially similar successor rule thereto), (b) the Company cannot obtain such certification, identification, information, documentation or other reporting requirement through reasonable diligence and (c) the Company otherwise would meet the requirements for application of Rule 252 (or a substantially similar successor rule thereto). In addition, Sections 1018(a)(iii) and 1018(a)(iv) above shall not be construed to require that a non-Mexican pension or retirement fund or a non-Mexican financial institution or any other Holder register with the Ministry of Finance for the purpose of establishing eligibility for an exemption from Mexican withholding tax or to require that a Holder or beneficial owner certify or provide information concerning whether it is or is not a tax-exempt pension or retirement fund. Upon the Trustee's receipt of timely written notification from the Company that the Holders or beneficial owners will be required to provide information or documentation, as -64- described in Section 1018(a)(iii) or 1018(a)(iv) above, the Trustee shall provide such notification to the Holders or beneficial owners, as the case may be. The Company shall, as soon as practicable and in no event later than 30 days following the due date for each payment of Mexican taxes withheld by the Company with respect to the Securities, provide the Trustee with a certified copy of the official receipt evidencing the payment of such taxes. The Trustee shall, for a period of five years following the due date for each payment, maintain in its files each such certified copy received from the Company. The Trustee shall, upon written request by the beneficial owner of a Security or any Paying Agent, provide such owner or Paying Agent with a copy of the certified copy of the receipt provided to the Trustee by the Company regarding the amount of Mexican tax withheld by the Company with respect to the Securities within 30 Business Days following the receipt by the Trustee of such request. In respect of the Securities issued hereunder, at least 10 days prior to the first date of payment of interest on the Securities and at least 10 days prior to each date, if any, of payment of principal or interest thereafter if there has been any change with respect to the matters set forth in the below-mentioned Officers' Certificate, the Company shall furnish the Trustee and each Paying Agent with an Officers' Certificate instructing the Trustee and such Paying Agent as to whether such payment of principal of or any interest on such Securities shall be made without deduction or withholding for or on account of any tax, duty, assessment or other governmental charge. If any such deduction or withholding shall be required by Mexico or under the federal laws of the United States, then such certificate shall specify, by country, the amount, if any, required to be deducted or withheld on such payment to Holders of such Securities, and the Company shall pay or cause to be paid to the Trustee or such Paying Agent Additional Amounts, if any, required by this Section 1018. The Company agrees to indemnify the Trustee and each Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by them in reliance on any Officers' Certificate furnished pursuant to this Section 1018. The Company shall pay all stamp and similar duties, if any, which may be imposed by Mexico, the United States of America or any other governmental entity or political subdivision therein or thereof, or any taxing authority of or in any of the foregoing, with respect to this Indenture or the initial issuance of the Securities. (b) Except as specifically provided in the Security or this Indenture, the Company shall not be required to make any payment with respect to any tax, duty, assessment or other governmental charge of whatever nature imposed or levied by any government or any political subdivision or taxing authority thereof or therein. (c) The Company shall provide each Paying Agent and any withholding agent under relevant tax regulations with copies of each certificate received by the Company from a Holder of a Security pursuant to the text of such Security. Each such Paying Agent and withholding agent shall retain each such certificate received by it for as long as any Security is outstanding and in no event for less than four years after its receipt, and for such additional period -65- thereafter, as set forth in an Officers' Certificate, as such certificate may become material in the administration of applicable tax laws. (d) All references in this Indenture to principal or interest in respect of any Security shall be deemed to mean and include all Additional Amounts, if any, payable in respect of such principal or interest, unless the context otherwise requires, and express mention of the payment of Additional Amounts in any provision hereof shall not be construed as excluding reference to Additional Amounts in those provisions hereof where such express mention is not made. (e) In the event that Additional Amounts actually paid with respect to the Securities are based on rates of deduction or withholding of Mexican taxes in excess of the appropriate rate applicable to the Holder or beneficial owner of such Securities, and, as a result thereof, such Holder or beneficial owner is entitled to make a claim for a refund or credit of such excess from Mexican tax authorities, then such Holder or beneficial owner shall, by accepting the Securities, be deemed to have assigned and transferred all right, title and interest to any such claim for a refund or credit of such excess to the Company. However, by making such assignment, the Holder or beneficial owner makes no representation or warranty that the Company will be entitled to receive such claim for a refund or credit and incurs no other obligation with respect thereto. SECTION 1019. Provision of Financial Information. Whether or not the Company is subject to Section 13(a) or 15(d) of the Exchange Act, or any successor provision thereto, the Company will file with the Commission the annual reports, quarterly reports and other documents which the Company would have been required to file with the Commission pursuant to such Section 13(a) or 15(d) if the Company were so subject, such documents to be filed with the Commission on or prior to the respective dates (the "Required Filing Dates") by which the Company would have been required so to file such documents if the Company were so subject. The Company shall also in any event (a) within 15 days of each Required Filing Date (i) transmit, or cause the Trustee to transmit, by mail to all Holders, as their names and addresses appear in the Security Register, without cost to such Holders, and (ii) file with the Trustee copies of the annual reports, quarterly reports and other documents which the Company would have been required to file with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act or any successor provisions thereto if the Company were subject to such Sections, and (b) if filing such documents by the Company with the Commission is not permitted under the Exchange Act, promptly upon written request supply copies of such documents to any prospective Holder. All such documents to be so filed or transmitted must be prepared in English and all financial statements included therein must be prepared in accordance with Mexican GAAP (with, in the case of annual financial statements, a reconciliation to U.S. GAAP as contemplated by the rules and regulations of the Commission), and include a convenience translation to U.S. dollars. SECTION 1020. Waiver of Certain Covenants. The Company may omit in any particular instance to comply with any covenant or condition set forth in Sections 1008 to 1019, inclusive, if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition, but no such -66- waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect; provided, however, with respect to an Offer to Purchase as to which an Offer has been mailed, no such waiver may be made or shall be effective against any Holder tendering Securities pursuant to such Offer, and the Company may not omit to comply with the terms of such Offer as to such Holder. ARTICLE ELEVEN REDEMPTION OF SECURITIES ------------------------ SECTION 1101. Right of Redemption. The Securities may be redeemed, at the option of the Company, as a whole but not in part, if, as a result of any amendment to, or change in, the laws (or any regulation or rulings thereunder) of Mexico or any political subdivision or taxing authority thereof or therein, or any amendment to or change in an official interpretation or application regarding such laws, regulations or rulings, which amendment, change, application or interpretation becomes effective on or after July 22, 1996, the Company pays or would be obligated for reasons outside its control, and after taking reasonable measures available to it to avoid such obligation, to pay Additional Amounts in respect of any Security pursuant to the terms and conditions thereof in excess of those attributable to the Mexican withholding tax of 15% imposed on interest payments to Holders, then, at the option of the Company, the Securities may be redeemed, as a whole but not in part, at any time, upon giving not less than 30 nor more than 60 days' notice by mail to the Holders (which notice shall be irrevocable), at a Redemption Price equal to the principal amount thereof, together with accrued interest to the Redemption Date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the Interest Payment Date that is on or prior to the Redemption Date) and Additional Amounts, if any, which would otherwise be payable; provided that (1) no such notice of redemption may be given earlier than 90 days prior to the earliest date on which the Company would but for such redemption be obligated to pay such Additional Amounts and (2) at the time such notice is given, such obligation to pay such Additional Amounts remains in effect. Prior to the publication of any notice of redemption pursuant to this Section 1101, the Company shall deliver to the Trustee (i) an Officers' Certificate stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the condition or conditions precedent to the right of the Company so to redeem have occurred and (ii) an Opinion of Mexican Counsel to the effect that the Company has or shall become obligated to pay such Additional Amounts as a result of such amendment or change. Such notice, once delivered by the Company to the Trustee, shall be irrevocable. SECTION 1102. Election to Redeem; Notice to Trustee. The election of the Company to redeem any Securities pursuant to Section 1101 shall be evidenced by a Board Resolution.

SECTION 1103. Notice of Redemption. Notices to redeem Securities shall be given to each Holder in the manner set forth in Section 106. Such notice will be given once not more than 60 days nor less than 30 days prior to the date fixed for redemption. Such notices will be deemed to have been given on the date of mailing. Notices to redeem Securities shall identify the Securities to be redeemed (including CUSIP numbers), specify the Redemption Date, the places of payment, that payment will be made upon presentation and surrender of the Securities to be redeemed, that interest accrued to the date, fixed for redemption (subject to the right of Holders of record on the relevant Record Date to receive interest on an Interest Payment Date that is on or prior to the Redemption Date) will be paid as specified in said notice, and that on and after said date interest thereon will cease to accrue. Such notice shall also state that the conditions precedent to such redemption have occurred and the Redemption Price. Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company's request, by the Trustee in the name and at the expense of the Company. SECTION 1104. Deposit of Redemption Price. Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date. SECTION 1105. Securities Payable on Redemption Date. If notice of redemption has been given in the manner set forth in Section 1103, the Securities shall become due and payable on the Redemption Date specified in such notice and upon presentation and surrender of the Securities at the place or places specified in such notice, the Securities shall be paid and redeemed by the Company at the places and in the manner herein specified and at the Redemption Price herein specified together with accrued interest (subject to the right of Holders of record on the relevant Record Date to receive interest on an Interest Payment Date that is on or prior to the Redemption Date) to the Redemption Date. From and after the Redemption Date, if monies for the redemption of Securities called for redemption shall have been made available at the office of the Paying Agent (or, if the Company is acting as its own Paying Agent, segregated and held in trust as provided in Section 1003), for redemption on the Redemption Date, the Securities called for redemption shall cease to bear interest, and the only right of the Holders of such Securities shall be to receive payment of the Redemption Price together with accrued interest (subject to the right of Holders of record on the relevant Record Date to receive interest on an Interest Payment Date that is on or prior to the Redemption Date) to the Redemption Date as aforesaid. If monies for the redemption of the Securities are not made available for payment until after the Redemption Date, the Securities called for redemption shall not cease to bear interest until such monies have been so made available. -68- If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid, bear interest from the Redemption Date at the rate borne by the Security.

(6) No Event of Default or event which with notice or passage of time or both would become an Event of Default shall have occurred and be continuing on the date of such deposit or, insofar as subsections 501(7) and (8) are concerned, at any time during the period ending on the 90th day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 90th day).

(9) Such Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company as defined in the Investment Company Act of 1940, as amended, or such trust shall be qualified under such act or exempt from regulation thereunder, in each case as set forth in an Opinion of U.S. Counsel delivered by the Company to the Trustee.

Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government Obligations (including the proceeds thereof) -71- deposited with the Trustee (or other qualifying trustee--collectively, for purposes of this Section 1205, the "Trustee") pursuant to Section 1204 in respect of the Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and interest, but such money need not be segregated from other funds except to the extent required by law. The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 1204 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Securities.

SECTION 1206. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in accordance with Section 1202 or 1203 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company's obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article Twelve until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 1202 or 1203; provided, however, that if the Company makes any payment of principal of or interest on any Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or the Paying Agent. ---------------------------- This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. -72- IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed, and the Trustee has caused its corporate seals to be hereunto affixed and attested, all as of the day and year first above written.
