If, but only if, Securities of a series are issuable as Bearer Securities, any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of Securities of such series may, alternatively, be embodied in and evidenced by the record of Holders of Securities of such series voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders of Securities of such series duly called and held in accordance with the provisions of Article Fifteen, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the 13 Holders signing such instrument or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 1506. Without limiting the generality of this Section 104, unless otherwise provided in or pursuant to this Indenture, a Holder, including a U.S. Depositary that is a Holder of a global Security, may make, give or take, by a proxy, or proxies, duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Inden ture to be made, given or taken by Holders, and a U.S. Depository that is a Holder of a global Security may provide its proxy or proxies to the beneficial owners of interests in any such global Security through such U.S. Depositary's standing instructions and customary practices. The Trustee or the Company shall fix a record date for the purpose of determining the Persons who are beneficial owners of interest in any permanent global Security held by a U.S. Depositary entitled under the procedures of such U.S. Depositary to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders. If such a record date is fixed, the Holders on such record date or their duly appointed proxy or proxies, and only such Persons, shall be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other action, whether or not such Holders remain Holders after such record date. No such request, demand, authorization, direction, notice, consent, waiver or other action shall be valid or effective if made, given or taken more than 90 days after such record date. (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. (c) The ownership, principal amount and serial numbers of Bearer Securities held by any Person, and the date of the commencement and the date of termination of holding the same, may be proved by the production of such Bearer Securities or by a certificate executed, as depositary, by any trust company, bank, banker or other depositary reasonably acceptable to the Company, wherever situated, if such certificate shall be deemed by the Trustee to be satisfactory, showing that at the date therein mentioned such Person had on deposit with such Depositary, or 14 exhibited to it, the Bearer Securities therein described; or such facts may be proved by the certificate or affidavit of the Person holding such Bearer Securities, if such certificate or affidavit is deemed by the Trustee to be satisfactory. The Trustee and the Company may assume that such ownership of any Bearer Security continues until (1) another certificate or affidavit bearing a later date issued in respect of the same Bearer Security is produced, (2) such Bearer Security is produced to the Trustee by some other Person, (3) such Bearer Security is surrendered in exchange for a Registered Security or (4) such Bearer Security is no longer Outstanding. (d) The fact and date of execution of any such instrument or writing pursuant to clause (c) above, the authority of the Person executing the same and the principal amount and serial numbers of Bearer Securities held by the Person so executing such instrument or writing and the date of the commencement and the date of termination of holding the same may also be proved in any other manner which the Trustee deems sufficient; and the Trustee may in any instance require further proof with respect to any of the matters referred to in this clause. (e) The ownership of Registered Securities shall be proved by the Security Register. (f) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, any Security Registrar, any Paying Agent or the Company in reliance thereon, whether or not notation of such action is made upon such Security. (g) Whenever for purposes of any Act to be taken hereunder by the Holders of a series of Securities denominated in a Foreign Currency (or any currency unit), the principal amount of Securities is required to be determined, the aggregate principal amount of such Securities shall be deemed to be that amount of Dollars that could be obtained for such principal amount on the basis of the spot rate of exchange for such Foreign Currency or such currency unit as determined by the Company or by an authorized exchange rate agent and evidenced to the Trustee by an Officers' Certificate as of the date taking of such Act by the Holders of the requisite percentage in principal amount of the Securities is evidenced to the Trustee. An exchange rate agent may be authorized in advance or from time to time by the Company, and maybe the Trustee or its Affiliate. Any such determination by the Company or by any such exchange rate agent shall be conclusive and binding on all Holders, the Company and the Trustee, and neither the Company nor any such exchange rate agent shall be liable therefor in the absence of bad faith. (h) If the Company shall solicit from the Holders of any Registered Securities, any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders of Registered Securities entitled to give such request, demand, 15 authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of Registered Securities of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite propor tion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstand ing Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. SECTION 105. Notices, Etc., to Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, or (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company. SECTION 106. Notice to Holders of Securities; Waiver. Where this Indenture provides for notice to Holders of Securities of any event, (i) if any of the Securities affected by such event are Registered Securities, such notice to the Holders thereof shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each such Holder affected by such event, at his address as it appears in the Security Register, within the time prescribed for the giving of such notice and (ii) if any of the Securities affected by such event are Bearer Securities, notice to the Holders thereof shall be sufficiently given (unless otherwise herein or in the terms of such Bearer Securities expressly provided) if published once in an Authorized Newspaper in New York, New York, and in such other city or cities, if any, as may be specified in such Securities and, if the Securities of such series are listed on any stock exchange outside the United States, in any place at which such Securities are listed on a securities exchange to the extent that such securities exchange so requires, and mailed to such Persons whose names and addresses as were previously filed with the Trustee, within the time prescribed for giving such notice. In any case where notice 16 to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. In case by reason of the suspension of publication of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause it shall be impracticable to publish any notice to Holders of Bearer Securities as provided above, then such publication in lieu thereof as shall be made with the approval of the Trustee shall constitute a sufficient publication of such notice. Neither failure to give notice by publication to Holders of Bearer Securities as provided above, nor any defect in any notice so published, shall affect the sufficiency of any notice mailed to Holders of Registered Securities as provided above. Any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly given or provided. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice as provided above, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. SECTION 107. Conflict with Trust Indenture Act. This Indenture is subject to the Trust Indenture Act and if any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

If any such tender or recovery is made in other than the Required Currency, the Trustee may, but shall not be obligated to, take such actions as it considers appropriate to exchange such other currency or currency unit for the Required Currency. The costs and risks of any such exchange, including without limitation the risks of delay and exchange rate fluctuation, shall be borne by the Company, the Company shall remain fully liable for any shortfall or delinquency in the full amount of the Required Currency then due and payable and in no circum stances shall the Trustee be liable therefor. The Company hereby 18 waives any defense of payment based upon any such tender or recovery which is not in the Required Currency, or which, when exchanged for the Required Currency by the Trustee, is less than the full amount of Required Currency then due and payable.

All Securities of any one series need not be issued at the same time and, unless otherwise so provided by the Company, a series may be reopened for issuances of additional Securities of such series or to establish additional terms of such series of Securities. If any of the terms of the series of Securities are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers' Certificate setting forth the terms of the series. SECTION 302. Currency; Denominations. Unless otherwise provided in or pursuant to this Indenture, the principal of, any premium and interest on and any Additional Amounts with respect to the Securities shall be payable in Dollars. The Securities of each series shall be issuable in such denominations as shall be specified as contemplated by Section 301.

Execution, Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Company by its Chairman of the Board, one of its Vice Chairmen, its President or one of its Vice Presidents, under its corporate seal reproduced thereon attested by the signature of its Secretary or one of its Assistant Secretaries or its Treasurer or one of its Assistant Treasurers. The Coupons, if any, shall be executed on behalf of the Company by its Chairman of the Board, its President or one of its Vice Presidents attested by its Secretary or any Assistant Secretary or its Treasurer or one of its Assistant Treasurers. The signature of any of these officers on the Securities (and Coupons, if any) may be manual or facsimile. Securities (and Coupons, if any) 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 (and Coupons, if any) or did not hold such offices at the date of such Securities (and Coupons, if any). At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities (with or without Coupons) of any series 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 the Company Order shall authenticate and deliver such Securities. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and, subject to Sections 315(a) through 315(d) of the Trust Indenture Act, shall be fully protected in relying upon, (i) an Opinion of Counsel stating to the effect that: (a) the form or forms of such Securities and Coupons, if any, have been established in conformity with the provisions of this Indenture; (b) the terms of such Securities and Coupons, if any, have been established in conformity with the provisions of this Indenture; (c) the terms of the Securities and Coupons, if any, have been established in accordance with the terms of this Indenture and all conditions precedent provided for in the Indenture relating to the Trustee's authentication and delivery of the Securities and Coupons, if any, will have been complied with; and (d) as to such other matters as the Trustee may reasonably request; and (ii) an Officers' Certificate stating that, all conditions precedent to the authentication and delivery of such Securities and Coupons, if any, appertaining thereto, have been 25 complied with and to the best knowledge of the Persons executing such certificate, no event which is, or after notice or lapse of time would become, an Event of Default with respect to any of the Securities shall have occurred and be continuing. The Trustee shall have the right to decline to authenticate and deliver such Securities if the Trustee, being advised by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith by its board of directors or trustees, executive committee, or a trust committee of directors or trustees and/or Responsible Officers shall determine that such action would expose the Trustee to personal liability to existing Holders or would adversely affect the Trustee's own rights, duties or immunities under this Indenture or otherwise. The Trustee shall not be required to authenticate Securities denominated in a coin or currency (or unit including a coin or currency) other than that of the United States of America if the Trustee reasonably determines that such Securities impose duties or obligations on the Trustee which the Trustee is not able or reasonably willing to accept; provided that the Trustee, upon a Company Request, will resign as Trustee with respect to Securities of any series as to which such a determination is made, prior to the issuance of such Securities, and will comply with the request of the Company to execute and deliver a supplemental indenture appointing a succes sor Trustee pursuant to Section 901. If all the Securities of any series are not to be issued at one time, it shall not be necessary to deliver an Opinion of Counsel and an Officers' Certificate at the time of issuance of each Security, but such opinion and certificate, with appropriate modifications, shall be delivered at or before the time of issuance of the first Security of such series. If the Company shall establish pursuant to Section 301 that the Securities of a series are to be issued in whole or in part in global form, then the Company shall execute and the Trustee shall, in accordance with this Section and the Company Order with respect to such series, authenticate and deliver one or more Securities in global form that (i) shall represent and shall be denominated in an amount equal to the aggregate principal amount of the Outstanding Securities of such series to be represented by such global Security or Securities, (ii) shall be registered, if in registered form, in the name of the Depositary for such Book-Entry Security or Securities or the nominee of such Depositary, (iii) shall be delivered by the Trustee to such Depositary or pursuant to such Depositary's instruction and (iv) where such Depositary is The Depository Trust Company, shall bear a legend substantially to the following effect: "Unless and until it is exchanged in whole or in part for Securities in certificated form, this Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary" or to such other effect as the Depositary and the Trustee may agree. Each Depositary designated pursuant to Section 301 for a Book-Entry Security in registered form must, at the time of its designation and at all times while it serves as Depositary, 26 be a clearing agency registered under the Securities Exchange Act of 1934 and any other applicable statute or regulation. The Trustee shall have no responsibility to determine if the Depositary is so registered. Each Depositary shall enter into an agreement with the Trustee governing their respective duties and rights with regard to Book-Entry Securities. Each Security shall be dated the date of its authentication, except that each Bearer Security, including any Bearer Security in global form, shall be dated as of the date specified or contemplated by Section 301. No Security or Coupon appertaining thereto 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 duly executed by the Trustee by manual signature of one of its authorized signatories, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Except as permitted by Section 306 or 307, the Trustee shall not authenticate and deliver any Bearer Security unless all appurtenant Coupons then matured have been detached and cancelled. SECTION 304. Temporary Securities. Pending the preparation of definitive Securities of any series, the Company may execute, and upon receipt of a Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor and form, with or without Coupons 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 conclusively evidenced by their execution of such Securities and Coupons, if any. Such temporary Securities may be in global form. Except in the case of temporary Securities in global form, each of which shall be exchanged in accordance with the provisions thereof, if temporary Securities of any series are issued, the Company will cause definitive Securities of such series to be prepared without unreasonable delay. After the preparation of definitive Securities of the same series and containing terms and provisions that are identical to those of any temporary Securities, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company pursuant to Section 1002 in a Place of Payment for such series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series (accompa nied by any unmatured Coupons appertaining thereto), the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of the same series of authorized denominations and of like tenor; provided, however, that no definitive Bearer Security shall be delivered in exchange 27 for a temporary Registered Security; and provided, further, that no definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security unless the Trustee shall have received from the person entitled to receive the definitive Bearer Security a certificate substantially in the form approved in the Board Resolutions relating thereto and such delivery shall occur only outside the United States. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series except as otherwise specified as contemplated by Section 301 with respect to the payment of interest on Bearer Securities in temporary form. SECTION 305. Registration, 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 of the Company maintained pursuant to Section 1002 in a Place of Payment being herein 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 Registered Securities and of transfers of Registered Securities. The Trustee is hereby appointed "Security Registrar" for the purpose of registering Registered Securities and transfers of Registered Securities as herein provided. In the event that the Trustee shall not be the Security Registrar, it shall have the right to examine the Security Register at all reasonable times. In the event that the Trustee shall cease to be Security Registrar with respect to a series of Securities, it shall have the right to examine the Security Register for such series at all reasonable times. Upon surrender for registration of transfer of any Registered Security of any series at the office or agency maintained pursuant to Section 1002 in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series, of any authorized denominations and of a like aggregate principal amount bearing a number not contemporaneously outstanding and containing identical terms and provisions. At the option of the Holder, Registered Securities of any series (except a Book-Entry Security representing all or a portion of the Securities of such series) may be exchanged for other Registered Securities of the same series, of any authorized denominations and of a like aggregate principal amount, upon surrender of the Registered Securities to be exchanged at such office or agency. Registered Securities may not be exchanged for Bearer Securities. Whenever any Registered Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive. At the option of the Holder, Bearer Securities of any series may be exchanged for Registered Securities (if the Securities of such series are issuable in registered form) or Bearer Securities (if Bearer Securities of such series are issuable in more than one denomination and such exchanges are permitted by such series) of the same series, of any authorized denominations 28 and of like tenor and aggregate principal amount, upon surrender of the Bearer Securities to be exchanged at any such office or agency, with all unmatured coupons and all matured Coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured Coupon or Coupons or matured Coupon or Coupons in default, such exchange may be effected if the Bearer Securities are accompanied by payment in funds accept able to the Company and the Trustee in an amount equal to the face amount of such missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such missing Coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; provided, however, that, except as otherwise provided in Section 1002, interest represented by Coupons shall be payable only upon presentation and surrender of those Coupons at an office or agency located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in exchange for a Registered Security of the same series after the close of business at such office or agency on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the Coupon relating to such Interest Payment Date or proposed date of payment, as the case may be (or, if such Coupon is so surrendered with such Bearer Security, such Coupon shall be returned to the person so surrendering the Bearer Security), and interest or Defaulted Interest, as the case may be, shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture. Notwithstanding any other provision of this Section, unless and until it is ex changed in whole or in part for Securities in certificated form, a Security in global form represent ing all or a portion of the Securities of a series may not be transferred except as a whole by the Depositary for such series to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor Depositary. If at any time the Depositary for the Securities of a series notifies the Company that it is unwilling or unable to continue as Depositary for the Securities of such series or if at any time the Depositary for the Securities of such series shall no longer be eligible under Section 303, the Company shall appoint a successor Depositary with respect to the Securities of such series. If a successor Depositary for the Securities of such series is not appointed by the Company within 90 days after the issuer receives such notice or becomes aware of such ineligibility, the Company's election pursuant to Section 301(20) shall no longer be effective with respect to the Securities of such series and the Company shall execute, and the Trustee, upon receipt of a 29 Company Order for the authentication and delivery of certificated Securities of such series of like tenor, shall authenticate and deliver Securities of such series in certificated form in an aggregate principal amount equal to the principal amount of the Security or Securities in global form representing such series in exchange for such Security or Securities in global form. The Company may at any time and in its sole discretion determine that the Securities of any series issued in the form of one or more global Securities shall no longer be represented by such global Security or Securities. In such event the Company shall execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of certificated Securities of such series of like tenor, shall authenticate and deliver, Securities of such series in certificated form and in an aggregate principal amount equal to the principal amount of the Security or Securities in global form representing such series in exchange for such Security or Securities in global form. If specified by the Company pursuant to Section 301 with respect to a series of Securities, the Depositary for such series of Securities may surrender a global Security of such series in exchange in whole or in part for Securities of such series in certificated form on such terms as are acceptable to the Company and such Depositary. Thereupon, the Company shall execute, and the Trustee shall authenticate and deliver, without service charge, (i) to each Person specified by such Depositary a new certificated Security or Securities of the same series of like tenor, of any authorized denomination as requested by such Person in aggre gate principal amount equal to and in exchange for such Person's beneficial interest in the global Security; and (ii) to such Depositary a new global security of like tenor in a denomination equal to the difference, if any, between the principal amount of the surrendered global Security and the aggregate principal amount of certificated Securities delivered to Holders thereof. In any exchange provided for in any of the preceding three paragraphs, the Company shall execute and the Trustee shall authenticate and deliver Securities in certificated form in authorized denominations. Upon the exchange of a global Security for Securities in certificated form, such global Security shall be cancelled by the Trustee. Unless expressly provided with respect to the Securities of any series that such Security may be exchanged for Bearer Securities, Securities issued in exchange for a Book-Entry Security pursuant to this Section shall be registered in such names and in such authorized denominations as the Depositary for such Book-Entry Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the 30 Trustee. The Trustee shall deliver such Securities to the Persons in whose names such Securities are so registered. 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 entitling the Holders thereof to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. Every Registered Security presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the Company or the Security Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange or redemption 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, 906 or 1107 not involving any transfer. Except as otherwise provided in or pursuant to this Indenture, the Company shall not be required (i) to issue, register the transfer of or exchange Securities of any series for a period of 15 days before the selection of any Securities of that series for redemption, or (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part, or (iii) to exchange any Bearer Security so selected for redemption except that such a Bearer Security may be exchanged for a Registered Security of that series and like tenor, provided that such Registered Security shall be simultaneously surrendered for redemption with written instruction for payment consistent with the provisions of this Indenture or (iv) to issue, register the transfer of or exchange any Security which, in accordance with its terms, has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid. SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security or Security with a mutilated Coupon appertaining to it is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security with Coupons corresponding to the Coupons, if any, appertaining to the surrendered Security of the same series and of like tenor and principal amount 31 and bearing a number not contemporaneously outstanding with Coupons corresponding to the Coupons, if any, appertaining to the surrendered Security. 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 or Security with a destroyed, lost or stolen Coupon 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 or Coupon has been acquired by a bona fide purchaser, the Company shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding with Coupons corresponding to the Coupons, if any, appertaining to the destroyed, lost or stolen Security. Notwithstanding the foregoing provisions of this Section 306, in case any such mutilated, destroyed, lost or stolen Security or Coupon has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security or Coupon, pay such Security or Coupon; provided, however, that payment of principal of and any premium or interest on or any Additional Amounts with respect to any Bearer Securities shall, except as otherwise provided in Section l002, be payable only at an office or agency located outside the United States and, unless otherwise specified as contemplated by Section 301, any interest on Bearer Securities and any Additional Amounts with respect to such interest shall be payable only upon presentation and surrender of the Coupons appertaining thereto. 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 of any series with its Coupons, if any, issued pursuant to this Section in lieu of any destroyed, lost or stolen Security, or in exchange for a Security to which a destroyed, lost or stolen Coupon appertains, shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security and its Coupons, if any, or the destroyed, lost or stolen Coupon, 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 of that series and their Coupons, if any, duly issued hereunder. The provisions of this Section, as amended or supplemented pursuant to this Indenture with respect to particular Securities or generally, 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 or Coupons. SECTION 307. Payment of Interest and Certain Additional Amounts; Rights to Interest and Certain Additional Amounts Preserved. 32 Unless otherwise provided as contemplated by Section 301, interest on and any Additional Amounts with respect to any Registered 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. Unless otherwise provided in or pursuant to this Indenture, in case a Bearer Security is surrendered in exchange for a Registered Security after the close of business (at an Office or Agency for such Security) on any Regular Record Date therefor and before the opening of business (at such Office or Agency) on the next succeeding Interest Payment Date therefore, such Bearer Security shall be surrendered without the Coupon relating to such Interest Payment Date and interest shall not be payable on such Interest Payment Date in respect of the Registered Security issued in exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture. Any interest on and any Additional Amounts with respect to any Registered Security of any series 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 Registered Securities of such series (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 Registered Security of such series 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 is provided in this Clause (1). Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of 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 of Registered Securities of such Series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an Authorized Newspaper of general circulation in the Borough of Manhattan, The City of New York, but such publication shall not be a condition precedent to the establishment of 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 of such series (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 33 (2). In case a Bearer Security is surrendered at the Office or Agency for such Security in exchange for a Registered Security after the close of business at such Office or Agency on any Special Record Date and before the opening of business at such Office or Agency on the related proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the Coupon relating to such proposed date of payment and Defaulted Interest shall not be payable on such proposed date of payment in respect of the Registered Security issued in exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture. (2) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such 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. At the option of the Company, interest on Registered Securities of any series that bear interest may be paid (i) by mailing a check to the address of the Person entitled thereto as such address shall appear in the Security Register or (ii) by wire transfer to an account maintained by the person entitled thereto as specified in the applicable Security Register. Notwithstanding the above, except as otherwise specified with respect to a series of Securities in accordance with the provisions of Section 301, a Holder of $10,000,000 or more in aggregate principal amount of Securities of the same series having the same Interest Payment Date shall, upon written request received by the Trustee prior to the Regular Record Date in respect of an interest payment, or the date which is 15 days before the Stated Maturity or date of redemption of the principal of (and premium, if any, on) the Securities, as the case may be, be entitled to receive payments of principal of (and premium, if any) and interest by wire transfer to an account maintained by such Holder with a bank located in the United States; provided, however, that no payment of principal (and premium, if any) will be made without prior present ment and surrender of the Securities. Subject to the foregoing provisions of this Section, each Security or Coupon, if any, delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security or Coupon, if any, shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security or Coupon. SECTION 308. Persons Deemed Owners. 34 Prior to due presentment of a Registered 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 Registered Security is registered as the owner of such Registered Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 307) interest on, and any Additional Amounts with respect to, such Registered Security and for all other purposes whatsoever, whether or not such Registered 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. No holder of any beneficial interest in any global Security held on its behalf by the Depositary shall have any rights under this Indenture with respect to such global Security, and such Depositary may be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such global Security for all purposes whatsoever. None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interest of a global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interest. The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of any Bearer Security and the bearer of any Coupon as the absolute owner of such Bearer Security or Coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes whatsoever, whether or not such Bearer Security or Coupon 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. No holder of any beneficial interest in any global Security held on its behalf by the Depositary shall have any rights under this Indenture with respect to such global Security, and such Depositary may be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such global Security for all purposes whatsoever. None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interest of a global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interest. SECTION 309. Cancellation.

If this Section is specified, as contemplated by Section 301, to be applicable to Securities and Coupons, if any, of any series, at the Company's option, either (a) the Company will be deemed to have been Discharged (as defined below) from its obligations with respect to Securities and Coupons, if any, of such series or (b) the Company will cease to be under any obligation to comply with any term, provision or condition set forth in (i) Article Eight and Section 1006 or (ii) the terms, provisions or conditions of such series specified pursuant to Section 301 (provided, however, that the Company may not cease to comply with any obligations as to which it may not be Discharged pursuant to the definition of "Discharged"), if, in the case of (a) and (b), with respect to the Securities and Coupons, if any, of such series on the 91st day after the applicable conditions set forth below in (x) and either (y) or (z) have been satisfied: (x) (1) the Company has paid or caused to be paid all other sums payable with respect to the Outstanding Securities and Coupons, if any, of such series (in addition to any required under (y) or (z)); and (2) the Company has delivered to the Trustee an Officers' Certifi cate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of the entire indebtedness on all Outstanding Securities and Coupons, if any, of any such series have been complied with; (y)(1) the Company shall have deposited or caused to be deposited irrevocably with the Trustee as a trust fund specifically pledged as security for, and dedicated solely to, the benefit of the Holders of the Securities and Coupons, if any, of such series (i) an amount (in such currency or currency unit in which the Outstanding Securities and Coupons, if any, of such series are payable) or (ii) U.S. Government Obligations (as defined below) or, in the case of Securities and Coupons, if any, denominated in a Foreign Currency, Foreign Government Securities (as defined below) denominated in such Foreign Currency, which through the payment of interest and principal in respect thereof in accordance with their terms will provide, not later than the due date of any payment of principal (including any premium), and interest, if any, under the Securities and Coupons, if any, of such series, Money in an amount or (iii) a combination of (i) and (ii) sufficient (in the opinion with respect to (ii) and (iii) of a nationally recognized 38 firm of independent public accountants expressed in a written certification thereof delivered to the Trustee) to pay and discharge each installment of principal of (including any premium), and interest, if any, on, and any Additional Amounts with respect to the Outstanding Securities and Coupons, if any, of such series on the dates such installments of interest or principal are due; (2) (i) no Event of Default or event (including such deposit) which with notice or lapse of time or both would become an Event of Default shall have occurred and be continuing on the date of such deposit, (ii) no Event of Default as defined in clause (6) or (7) of Section 501, or event which with notice or lapse of time or both would become an Event of Default under either such clause, shall have occurred within 90 days after the date of such deposit and (iii) such deposit and the related intended consequence under (a) or (b) will not result in any default or event of default under any material indenture, agreement or other instrument binding upon the Company or any Subsidiary or any of their properties; and (3) the Company shall have delivered to the Trustee (A) an Opinion of Counsel to the effect that Holders of the Securities and Coupons, if any, of such series will not recognize income, gain or loss for Federal income tax purposes as a result of the Company's exercise of its option under this Section 403 and will be subject to Federal income tax in the same amount, in the same manner and at the same times as would have been the case if such option had not been exercised; and (B) if the Securities of such series are then listed on any exchange, an Opinion of Counsel that the Securities of such series shall not be delisted as a result of the exercise of this option; (z) the Company has properly fulfilled such other means of satisfaction and discharge as is specified, as contemplated by Section 301, to be applicable to the Securities and Coupons, if any, of such series. Any deposits with the Trustee referred to in clause (y)(1) above shall be irrevocable and shall be made under the terms of an escrow trust agreement in form and substance satisfactory to the Trustee. If any Outstanding Securities and Coupons, if any, of such series are to be redeemed prior to their Stated Maturity, whether pursuant to any mandatory redemption provisions or in accordance with any mandatory sinking fund requirement, the applicable escrow trust agreement will provide therefor and the Company will make such arrangements as are satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company. 39 "Discharged" means that the Company will be deemed to have paid and discharged the entire indebtedness represented by, and obligations under, the Securities and Coupons, if any, of the series as to which this Section is specified as applicable as aforesaid and to have satisfied all the obligations under this Indenture relating to the Securities and Coupons, if any, of such series (and the Trustee, at the expense of the Company, will execute proper instruments acknowledging the same), except (A) the rights of Holders thereof to receive, from the trust fund described in clause (y)(1) above, payments of the principal of, premium and the interest, if any, on such Securities and Coupons, if any, when such payments are due, (B) the Company's obligations with respect to such Securities and Coupons, if any, under Sections 305 and 306 (insofar as applicable to Securities of such series), 402, 1002 and 1003 (last paragraph only) and the Company's obligations to the Trustee under Sections 605 and 606 and (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder, will survive such discharge. The Company will reimburse the trust fund for any loss suffered by it as a result of any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or Foreign Government Securities, as the case may be, or any principal, premium or interest paid on such Obligations, and, subject to the provisions of Section 605, will indemnify the Trustee against any claims made against the Trustee in connection with any such loss. "Foreign Government Securities" as used in Section 403 means, with respect to Securities and Coupons, if any, of any series that are denominated in a Foreign Currency, securities that are (i) direct obligations of the government that issued such currency for the payment of which obligations its full faith and credit is pledged or (ii) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of such government (the timely payment of which is unconditionally guaranteed as a full faith and credit obligation of such government) which, in either case under clauses (i) or (ii), are not callable or redeemable at the option of the issuer thereof and will also include a depository receipt issued by a bank or trust company as custodian with respect to any such Foreign Government Obligation or a specified payment of interest on or principal of any such Foreign Government Obligation held by such custodian for the account of the holder of a depository receipt; provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depository receipt from any amount received by the custodian in respect of the Foreign Government Obligations or the specific payment of interest on or principal of the Foreign Government Obligation evidenced by such depository receipt.

or (8) any other Event of Default provided with respect to Securities of that series. SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an Event of Default with respect to Securities of any series at the time Outstand ing occurs and is continuing, then in every such case the Trustee or the Holders of not less than 33-1/3% in principal amount of the Outstanding Securities of that series may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) of all of the 42 Securities of that series 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 amount (or specified amount) shall become immediately due and payable. At any time after such a declaration of acceleration with respect to Securities of any series 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 of that series, 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 installments of any interest on and Additional Amounts with respect to all Securities of that series and any Coupons appertaining thereto; (B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and interest thereon and any Additional Amounts with respect thereto at the rate or rates prescribed therefor in such Securities; (C) to the extent that payment of such interest or Additional Amounts is lawful, interest upon overdue installments of any interest and Additional Amounts at the rate or rates prescribed therefor in such Securities; and (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and (2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of (and premium, if any,) and interest on, and any Additional Amounts with respect to Securities of that series 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 installment of interest on or any Additional Amounts with respect to any Security or Coupon, if any, when such interest or 43 Additional Amounts become 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 (or premium, if any, on) any Security at the Maturity thereof; the Company will, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities or Coupons, if any, the whole amount of Money then due and payable on such Securities and any Coupons for principal (and premium, if any) and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and pre mium, if any) and on any overdue interest and Additional Amounts, at the rate or rates prescribed therefor in such Securities or Coupons, if any, and, in addition thereto, such further amount of Money as shall be sufficient to cover the costs and expenses of collection, including the reason able compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. If the Company fails to pay the Money and is required to pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of the Trustee, the Trustee in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the Money so due and unpaid and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon such Securities or Coupons, if any, and collect the Money adjudged or decreed to be paid in the manner provided by law out of the property of the Company or any other obligor upon such Securities or Coupons, if any, wherever situated. If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series or Coupons, if any, 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. SECTION 504. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any overdue principal, premium, interest or Additional Amounts) shall be entitled and empowered, by intervention in such proceeding or otherwise, 44 (i) to file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Securities of such series, of the principal and any premium, interest and Additional Amounts owing and unpaid in respect of the Securities and any Coupons appertaining thereto and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents or counsel) and of the Holders of Securities or any Coupons allowed in such judicial proceeding; and (ii) to collect and receive any Monies 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 of Securities or any Coupons 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 of Securities or any Coupons, to pay to the Trustee any amount due to 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 605. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security or any Coupon any plan of reorganization, arrangement, adjustment or composition affecting the Securities or Coupons or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Security or any Coupon in any such proceeding. SECTION 505. Trustee May Enforce Claims Without Possession of Securities or Coupons. All rights of action and claims under this Indenture or any of the Securities or Coupons may be prosecuted and enforced by the Trustee without the possession of any of the Securities or Coupons 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 or judgment shall, after provision for the payment of the reasonable compensation, expense, disbursements and advances of the Trustee, its agents and counsel, and for any other amounts due to the Trustee under Section 605, be for the ratable benefit of the Holders of the Securities or any Coupons 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 premium, if any) or interest or Additional Amounts, 45 upon presentation of the Securities or Coupons, or both, as the case may be, 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 and any predecessor Trustee under Section 605; and Second: To the payment of the amounts then due and unpaid for principal of (and premium, if any), interest and Additional Amounts on the Securities and any Coupons 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 and any Coupons for principal (and premium, if any) and interest and Additional Amounts, respectively; and Third: The balance, if any, to the Person or Persons entitled thereto. SECTION 507. Limitation on Suits. No Holder of any Security of any series or any Coupons appertaining thereto 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 (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series; (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series 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 of that series; it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture or any Security to affect, disturb or prejudice the rights of any other of such Holders or Holders of Securities of any other series, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. 46 SECTION 508. Unconditional Right of Holders to Receive Principal and any Premium, Interest and Additional Amounts. Notwithstanding any other provision in this Indenture, the Holder of any Security or Coupon shall have the right, which is absolute and unconditional, to receive payment of the principal of, any premium and (subject to Sections 305 and 307) interest on, and any Additional Amounts with respect to such Security or payment of such Coupon, as the case may be, on the respective Stated Maturity or Maturities therefor specified in such Security or Coupon (or, in the case of redemption, on the Redemption Date or, in the case of repayment at the option of such Holder if provided in or pursuant to this Indenture, on the date such repayment is due) and to institute suit for the enforcement of any such payment, and such right 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 each such Holder shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and each such Holder 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 or Coupons 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. 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 or Coupon 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 such Holder, as the case may be. 47 SECTION 512. Control by Holders. The Holders of a majority in principal amount of the Outstanding Securities of any series 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, with respect to the Securities of such series and any Coupons appertaining thereto, provided that (1) such direction shall not be in conflict with any rule of law or with this Indenture; (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; and (3) such direction is not unduly prejudicial to the rights of the other Holders of Securities of such series not joining in such action. SECTION 513. Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series and any Coupons waive any past default hereunder with respect to such series and its consequences, except a default (1) in the payment of the principal of (or premium, if any) or interest on any Security of such series or any Coupons appertaining thereto, 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 of such series 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. 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 48 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. SECTION 515. Judgment Currency. The following provisions of this Section 515 shall apply to the extent permissible under applicable law: Judgments in respect of any obligations of the Company under any Securities or Coupons, if any, of any series shall be rendered in the currency or currency unit in which such Securities or Coupons are payable. If for the purpose of obtaining a judgment in any court with respect to any obligation of the Company hereunder or under any Security or Coupon, it shall become necessary to convert into any other currency or currency unit any amount in the currency or currency unit due hereunder or under such Security or Coupon, then such conversion shall be made at the Conversion Rate (as defined below) as in effect on the date the Company shall make payment to any person in satisfaction of such judgment. If pursuant to any such judgment, conversion shall be made on a date other than the date payment is made and there shall occur a change between such Conversion Rate and the Conversion Rate as in effect on the date of payment, the Company agrees to pay such additional amounts (if any) as may be necessary to ensure that the amount paid is the amount in such other currency or currency unit which, when converted at the Conversion Rate as in effect on the date of payment or distribution, is the amount then due hereunder or under such Security or Coupon. Any amount due from the Company under this Section 515 shall be due as a separate debt and is not to be affected by or merged into any judgment being obtained for any other sums due hereunder or in respect of any Security or Coupon so that in any event the Company's obligations hereunder or under such Security or Coupon will be effectively maintained as obligations in such currency or currency unit. In no event, however, shall the Company be required to pay more in the currency or currency unit due hereunder or under such Security or Coupon at the Conversion Rate as in effect when payment is made than the amount of currency or currency unit stated to be due hereunder or under such Security or Coupon.

Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series. It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. SECTION 903. Execution of Supplemental Indentures. As a condition to executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee's own rights, duties or immunities under this Indenture or otherwise. SECTION 904. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. SECTION 905. Conformity with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act as then in effect. SECTION 906. Reference in Securities to Supplemental Indentures. Securities, including any Coupons, of any series authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities including any Coupons of any series so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and 64 authenticated and delivered by the Trustee in exchange for Outstanding Securities including any Coupons of such series. ARTICLE TEN COVENANTS SECTION 1001. Payment of Principal, Premium and Interest and Additional Amounts. The Company covenants and agrees for the benefit of the Holders of each series of Securities that it will duly and punctually pay the principal of (and premium, if any) and interest on and any Additional Amounts with respect to the Securities of that series in accordance with the terms of the Securities and this Indenture. The interest on Securities with Coupons appertaining thereto shall be payable only upon presentation and surrender of the several Coupons for such interest installments as are evidenced thereby as they severally mature. The interest, if any, on any temporary Bearer Security shall be paid, as to any installment of interest evidenced by a Coupon attached thereto only upon presentation and surrender of such Coupon and, as to other installments of interest, only upon presentation of such Security for notation thereon of the payment of such interest. SECTION 1002. Maintenance of Office or Agency. If Securities of a series are issued as Registered Securities, the Company will maintain in each Place of Payment for any series of Securities an office or agency where Securities and Coupons, if any of that series may be presented or surrendered for payment, where securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. If Securities of a series are issuable as Bearer Securities, the Company will maintain an office or agency, (A) subject to any laws or regulations applicable thereto, in a Place of Payment for that series which is located outside the United States, where Securities of that series and related coupons may be presented and surrendered for payment; provided, however, that if the Securities of that series are listed on The International Stock Exchange of the United Kingdom and the Republic of Ireland Limited, the Luxembourg Stock Exchange or any other stock exchange located outside the United States and such stock exchange shall so require, the Company will maintain a Paying Agent for the Securities of that series in London, Luxembourg or any other required city located outside the United States, as the case may be, so long as the Securities of that series are listed on such exchange and (B) subject to any laws or regulations applicable thereto, in a Place of Payment for that series located outside the United States, where Securities of that series may be surrendered for exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of any such office or agency. If at any time the Company shall fail to maintain any 65 such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, except that Bearer Securities of such series and any Coupons appertaining thereto may be presented and surrendered for payment at the place specified for the purpose with respect to such Securities as provided in or pursuant to this Indenture, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. Except as otherwise provided in or pursuant to this Indenture, no payment of principal or interest on Bearer Securities shall be made at any office or agency of the Company in the United States, by check mailed to any address in the United States, by transfer to an account located in the United States or upon presentation or surrender in the United States of a Bearer Security or coupon for payment, even if the payment would be credited to an account located outside the United States; provided, however, that, if the Securities of a series are denominated and payable in Dollars, payment of principal of and any interest on or any Additional Amounts with respect to any such Bearer Security shall be made at the office of the Company's Paying Agent in Salt Lake City, or such place as the Company may designate if (but only if) payment in Dollars of the full amount of such principal, interest or Additional Amounts, as the case may be, at all offices or agencies outside the United States maintained for the purpose by the Company in accordance with this Indenture is illegal or effectively precluded by exchange controls or other similar restrictions. The Company may also from time to time designate one or more other offices or agencies where the Securities (including any Coupons, if any) of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for Securities (including any Coupons, if any) of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. Unless otherwise provided in or pursuant to this Indenture, the Company hereby designates as the Place of Payment for each series Salt Lake City, and initially appoints the office or agency of the Corporate Trust Office of the Trustee for such purpose. Pursuant to Section 301(6) of this Indenture, the Company may subsequently appoint a place or places in Salt Lake City where such Securities may be payable. SECTION 1003. Money for Securities Payments to Be Held in Trust. If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it shall, on or before each due date of the principal of (and premium, if any) or interest on or any Additional Amounts with respect to any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum of Money sufficient to pay the principal (and premium, if any), interest or Additional Amounts so becom- 66 ing due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and shall promptly notify the Trustee of its action or failure so to act. Whenever the Company shall have one or more Paying Agents for any series of Securities, it shall, on or prior to (but in the case of payments to be made at a Place of Payment outside of the United States, its territories, possessions and areas subject to its jurisdiction, at least one New York Business Day before) each due date of the principal of, any premium or interest on or any Additional Amounts with respect to any Securities of such series, deposit with any Paying Agent a sum of Money sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of its action or failure so to act. The Company shall cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall: (1) hold all sums held by it for the payment of the principal of (and premium, if any) or interest on or any Additional Amounts with respect to Securities of that series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; (2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment of principal (and premium, if any) or interest on or any Additional Amounts with respect to the Securities of such series; and (3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such Money. Any Money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest on or any Additional Amounts with respect to any Security of any series and remaining unclaimed for 2 67 years after such principal (and premium, if any) or interest or Additional Amounts shall have become due and Payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security and Coupon, if any, shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such Money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in an Authorized Newspaper in each Place of Payment for such series or to be mailed to Holders of Registered Securities of such series notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication or mailing nor shall it be later than 2 years after such principal and any premium or interest or Additional Amounts shall have become due and payable, any unclaimed balance of such Money then remaining will be repaid to the Company. SECTION 1004. Additional Amounts. If any Securities of a series provide for the payment of Additional Amounts, the Company agrees to pay to the Holder of any such Security or any Coupon appertaining thereto Additional Amounts as provided therein. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series or any Coupon or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided by the terms of such series established hereby or pursuant hereto to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms and express mention of the payment of Additional Amounts (if applicable) in any provision hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made. Except as otherwise provided in or pursuant to this Indenture, if the Securities of a series provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect to such series of Securities (or if the Securities of such series shall not bear interest prior to Maturity, the first day on which a payment of principal is made), and at least 10 days prior to each date of payment of principal or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers' Certificate, the Company shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if other than the Trustee, an Officers' Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of or interest on the Securities of such series shall be made to Holders of Securities of such series or the Coupons appertaining thereto who are United States Aliens without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of such series. If any such withholding shall be required, then such Officers' Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities or Coupons and the Company agrees to pay to the 68 Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. The Company covenants to indemnify the Trustee and any 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 any of them in reliance on any Officers' Certificate furnished pursuant to this Section. SECTION 1005. Corporate Existence. Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, rights (charter and statutory) and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. SECTION 1006. Limitation on Liens. Except as hereinafter in this Section 1006 expressly permitted and as permitted by Section 801, so long as any of the Securities remain Outstanding, the Company will not at any time directly or indirectly create, assume or suffer to exist, and will not cause, suffer or permit any Subsidiary to create, assume or suffer to exist, otherwise than in favor of the Company or a Subsidiary, any mortgage, pledge, lien, encumbrance of or upon or security interest (collectively, "Liens") upon any of its properties or assets, real, personal or mixed, whether owned at the date of this Indenture or thereafter acquired, or of or upon, any income or profits therefrom, without making effective provision, and the Company covenants that in any such case it will make or cause to be made effective provision, whereby the Securities then or thereafter Outstanding shall be secured by such Liens equally and ratably with any and all other obligations and indebtedness thereby secured, so long as any such other obligations or indebtedness shall be so secured. Nothing in this Section 1006 shall be construed to prevent the Company or any Subsidiary from creating, assuming or suffering to exist Liens of the following character, to all of which the provisions of the first paragraph of this Section 1006 shall not be applicable: (a) Liens existing as of the date of this Indenture; (b) Any purchase money mortgage or Lien created to secure all or part of the purchase price of any property (or to secure a loan made to the Company or any Subsidiary to enable it to acquire the property described in such mortgage or in any applicable security agreement); provided that such Lien shall extend only to the property so acquired, improvements thereon, replacements thereof and the income or profits therefrom; (c) Liens on any property at the time of the acquisition thereof, whether or not assumed by the Company or a Subsidiary; provided that such Lien shall extend only to the 69 property so acquired, improvements thereon, replacements thereof and the income or profits therefrom; (d) Liens on any property or any contract for the sale of any product or service, or any rights thereunder or any proceeds therefrom, acquired or constructed by the Company or a Subsidiary, and created not later than twelve months after (i) such acquisition or completion of such construction, or (ii) commencement of operation of such property, whichever is later; provided that such Lien shall extend only to the property so acquired or constructed, improvements thereon, replacements thereof and the income or profits therefrom; (e) Liens on the properties or assets, real, personal or mixed, of a Subsidiary, or of or upon or in any income or profits therefrom, which is outstanding at the time such Subsidiary becomes a Subsidiary;

(i) Any refunding or extension of maturity, in whole or in part, of any obligation or indebtedness secured by any Lien created, existing or assumed in accordance with the provisions of Clauses (a) through (h) above, inclusive, provided that the principal amount of the obligation or indebtedness secured by such refunding or extended Liens shall not exceed the principal amount of the obligation or indebtedness to be refunded or extended outstanding at the time of such refunding or extension, together with related financing costs, and that such refunding or extended Liens shall be limited in lien to the same property that secured the obligation or in debtedness refunded or extended, and property substituted therefor and property 70 acquired after the date thereof and subject to the lien thereof, in accordance with the provisions of such refunding or extension; (j) Liens on any office equipment or data processing equipment (including, without limitation, computer and computer peripheral equipment) or any motor vehicles, tractors or trailers; (k) Liens of or upon or in current assets of the Company or a Subsidiary, determined in accordance with GAAP, created or assumed to secure indebtedness incurred in the ordinary course of business;

In the event that the Company or any Subsidiary shall hereafter secure the Securities equally and ratably with any other obligation or indebtedness pursuant to the provisions of this Section 1006, the Trustee is hereby authorized to enter into an indenture supplement 72 al hereto and to take such action, if any, as it may deem advisable to enable it to enforce effectively the rights of the Holders of the Securities so secured, equally and ratably with such other obligation or indebtedness. The Trustee may accept an Officers' Certificate and Opinion of Counsel as conclusive evidence that any such supplemental indenture or steps taken to secure the Securities equally and ratably comply with the provisions of this Section 1006. SECTION 1007. Waiver of Covenant. The Company may omit in any particular instance to comply with any term, provision or condition set forth in Article Eight and Sections 1005 and 1006, if before the time for such compliance the Holders of (i) a majority in principal amount of the Outstanding Securities or (ii) in case less than all of the several series of Securities then Outstanding are affected by the omission, at least a majority in principal amount of the Outstanding Securities of each series so affected voting as a single class shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision 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 term, provision or condition shall remain in full force and effect. SECTION 1008. Statements as to Compliance; Notice of Certain Defaults. (a) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year, a written statement (which need not be contained in or accompanied by an Officers' Certificate) signed by the principal executive officer, the principal financial officer or the principal accounting officer of the Company stating that (1) a review of the activities of the Company during such year and of performance under this Indenture has been made under his or her supervision, and (2) to the best of his or her knowledge, based on such review, (a) the Company has complied with all the conditions and covenants imposed on it under this Indenture throughout such year, or, if there has been a default in the fulfillment of any such condition or covenant, specifying each such default known to him or her and the nature and status thereof, and (b) no event has occurred and it continuing which is, or after notice or lapse of time or both would become, an Event of Default, or, if such an event has occurred and is continuing, specifying each such event known to him and the nature and status thereof.

Applicability of Article. Securities (including Coupons, if any) of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified or contemplated by Section 301 for Securities of any series) in accordance with this Article. SECTION 1102. Election to Redeem; Notice to Trustee. The election of the Company to redeem any Securities (including Coupons, if any) shall be evidenced by a Board Resolution. In case of any redemption at the election of the Company of all or less than all of the Securities (including Coupons, if any) of any series, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed. In the case of any redemption of Securities (including Coupons, if any) prior to the expiration of any restriction on such redemption provided in the terms of such Securities and Coupons, if any, or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers' Certificate evidencing compliance with such restriction. SECTION 1103. Selection by Trustee of Securities to be Redeemed. If less than all the Securities (including Coupons, if any) of any series with the same terms are to be redeemed, the particular Securities (including Coupons, if any) to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities (including Coupons, if any) of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions (equal to the minimum authorized denomina tion for Securities (including Coupons, if any) of that series or any integral multiple thereof) of the principal amount of Securities (including Coupons, if any) of such series of a denomination larger than the minimum authorized denomination for Securities of that series. The Trustee shall promptly notify the Company in writing of the Securities (including Coupons, if any) selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities 74 redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. SECTION 1104. Notice of Redemption. Notice of redemption shall be given not less than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to each Holder of Securities to be redeemed, as provided in Section 105. Each such notice of redemption shall specify the Redemption Date, the Redemption Price, the Place or Places of Payment, the CUSIP number of such Securities, if any, that the Securities of such series are being redeemed at the option of the Company pursuant to provisions contained in the terms of the Securities of such series or in a supplemental indenture establishing such series, if such be the case, together with a brief statement of the facts permitting such redemption, that payment will be made upon presentation and surrender of the applicable Securities, that all Coupons, if any, maturing subsequent to the date fixed for redemption shall be void, that any interest accrued to the Redemption Date will be paid as specified in said notice, and that on and after said Redemption Date any interest thereon or, in case of partial redemptions, on the portions thereof to be redeemed, will cease to accrue. If less than all the Securities of any series are to be redeemed the notice of redemption shall specify the numbers of the Securities of such series to be redeemed, and, if only Bearer Securities of any series are to be redeemed, and if such Bearer Securities may be exchanged for Registered Securities, the last date on which exchanges of Bearer Securities for Registered Securities not subject to redemption may be made. In case any Security of any series is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the Redemption Date, upon surrender of such Security and any Coupons appertaining thereto, a new Security or Securities of such series in principal amount equal to the unredeemed portion thereof and with appropriate Coupons will be issued, or, in the case of Registered Securities providing appropriate space for such notation, at the option of the Holders, the Trustee, in lieu of delivering a new Security or Securities as aforesaid, may make a notation on such Security of the payment of the redeemed portion thereof. Notice of redemption of Securities and Coupons, if any, 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 1105. Deposit of Redemption Price. On or before (but in the case of payments to be made at a Place of Payment outside of the United States, its territories, possessions and areas subject to its jurisdiction, at least one New York Business Day before) any Redemption Date, the Company shall deposit in immediately available funds 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 75 amount of Money in the relevant currency (or a sufficient number of currency units, as the case may be) sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) any accrued interest on and Additional Amounts with respect to all the Securities or portions thereof which are to be redeemed on that date. SECTION 1106. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest and the Coupons for such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Except as provided in the next succeeding paragraph, upon surrender of any such Security (including Coupons, if any) for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest and Additional Amounts to the Redemption Date; provided, however, that installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only upon presentation and surrender of Coupons for such interest (at an Office or Agency located outside the United States except as otherwise provided in Section 1002), and provided, further, that installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307. If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant Coupons maturing after the Redemption Date, such Bearer Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Bearer Security shall surrender to the Trustee or any Paying Agent any such missing Coupon in respect of which a deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that any interest or Additional Amounts represented by Coupons shall be payable only upon presentation and surrender of those Coupons at an office or agency located outside of the United States except as otherwise provided pursuant to Sections 901(10) and 1002. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. 76 SECTION 1107. Securities Redeemed in Part. Any Registered Security (including Coupons, if any) which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Registered Security or Securities (with appropriate Coupons, if any, attached) of the same series, containing identical terms and provisions, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security (including Coupons, if any) so surrendered. If a Security in global from is so surrendered, the Company shall execute and the Trustee shall authenticate and deliver to the U.S. Depository or other depository for such Security in global form as shall be specified in the Company Order with respect thereto to the Trustee, without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Security in global form so surrendered. ARTICLE TWELVE SINKING FUNDS SECTION 1201. Applicability of Article. The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series except as otherwise specified as contemplated by Section 301 for Securities of such series. The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a "mandatory sinking fund payment," and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an "optional sinking fund payment." If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series. SECTION 1202. Satisfaction of Sinking Fund Payments with Securities. The Company (1) may deliver outstanding Securities of a series (other than any previously called for redemption or any of such Securities in respect of which cash shall have been released to the Company), together in the case of any Bearer Securities of such series with all unmatured Coupons appertaining thereto, and (2) may apply as a credit Securities of a series which have been redeemed either at the election of the Company pursuant to the terms of such 77 Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of such series required to be made pursuant to the terms of such Securities as provided for by the terms of such series; provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. SECTION 1203. Redemption of Securities for Sinking Fund. Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an Officers' Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 1202 and will also deliver to the Trustee any Securities to be so delivered. Not less than 30 nor more than 60 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107. ARTICLE THIRTEEN REPAYMENT AT THE OPTION OF HOLDERS SECTION 1301. Applicability of Article. Securities of any series which are repayable at the option of the Holders thereof before their Stated Maturity shall be repaid in accordance with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of Securities before their Stated Maturity, for purposes of Section 309, shall not operate as a payment, redemption or satisfaction of the indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the Trustee with a directive that such Securities be cancelled. Notwithstanding anything to the contrary contained in this Section 1301, in connection with any repayment of Securities, the Company may arrange for the purchase of any Securities by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to the Holders of such Securities on or before the close of business on the repayment date an amount not less than the repayment price payable by the Company on repayment of such Securities, and the obligation 78 of the Company to pay the repayment price of such Securities shall be satisfied and discharged to the extent such payment is so paid by such purchasers. ARTICLE FOURTEEN SECURITIES IN FOREIGN CURRENCIES SECTION 1401. Applicability of Article. Whenever this Indenture provides for (i) any action by, or the determination of any of the rights of, Holders of Securities of any series in which not all of such Securities are denominated in the same Currency, or (ii) any distribution to Holders of Securities, in the absence of any provision to the contrary in the form of Security of any particular series, any amount in respect of any Security denominated in a Currency other than Dollars shall be treated for any such action or distribution as that amount of Dollars that could be obtained for such amount at the noon buying rate in the City of New York for cable transfers in foreign currencies as certified for customs purposes by the Federal Reserve Bank of New York and as of the record date with respect to Registered Securities of such series (if any) for such action, determination of rights or distribution (or, if there shall be no applicable record date, such other date reasonably proximate to the date of such action, determination of rights or distribution) as the Company may specify in a written notice to the Trustee.
