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.

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 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. <PAGE 14>

(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.

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, 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 proportion 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 Outstanding 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. <PAGE 15>

In any case where notice 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. <PAGE 16>

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.

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.

SECTION 111. Benefits of Indenture.

Nothing in this Indenture, any Security or any Coupon, express or implied, shall give to any Person, other than the parties hereto, any Security Registrar, any paying agent and their successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

SECTION 113. Moneys of Different Currencies to be Segregated.

The Trustee shall segregate monies, funds, and accounts held by the Trustee hereunder in one currency (or unit thereof) from any monies, funds or accounts in any other currencies (or units thereof), notwithstanding any provision herein which would otherwise permit the Trustee to commingle such amounts.

SECTION 114. Payment to be in Proper Currency.

The following provisions of this Section 114 shall apply to the extent permitted by applicable law: In the case of any Security payable in any particular currency or currency unit (the "Required Currency"), except as otherwise provided herein, therein or in or pursuant to the related Board Resolution or supplemental indenture or as contemplated by Section 301, the obligation of the Company to make any payment of principal, premium or interest thereon shall not be discharged or satisfied by any tender by the Company, or recovery by the Trustee, in any currency or currency unit other than the Required Currency, except to the extent that such tender or recovery shall result in the Trustee timely holding the full amount of the Required Currency then due and payable. 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 circumstances shall the Trustee be liable therefor. The Company hereby 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.

SECTION 115. Language of Notices.

Any request, demand, authorization, direction, notice, consent, election or waiver required or permitted under this Indenture shall be in the English language, except that, if the Company so elects, any published notice may be in an official language of the country of publication.

SECTION 116. Legal Holidays.

In any case where any Interest Payment Date, Stated Maturity or Maturity of any Security shall be a Legal Holiday at any Place of Payment, then (notwithstanding any other provision of this Indenture, any Security or any Coupon other than a provision in this Indenture, any Security or Coupon that specifically states that such provision shall apply in lieu of this Section) payment need not be made at such Place of Payment on such date, but may be made on the next succeeding day that is a Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or at the Stated Maturity or Maturity, and no interest shall accrue on the amount payable on such date or at such time for the period from and after such Interest Payment Date or Stated Maturity or Maturity, as the case may be. <PAGE 18>

SECTION 303. Execution, Authentication, Delivery and Dating.

The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its President or one of its Vice Presidents, under its corporate seal reproduced thereon attested by 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 Vice 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 <PAGE 24>

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 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 successor 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.
<PAGE 25>

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, be a clearing agency registered under the Exchange Act 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 (accompanied 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 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 <PAGE 26>

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 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 acceptable 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 <PAGE 27>

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 exchanged in whole or in part for Securities in certificated form, a Security in global form representing 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 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.
<PAGE 28>

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 aggregate 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 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 <PAGE 29>

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 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. <PAGE 30>

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.

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 <PAGE 31>

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 (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 <PAGE 32>

the United States; provided, however, that no payment of principal (and premium, if any) will be made without prior presentment 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.

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. <PAGE 33>

SECTION 309. Cancellation.

All Securities and Coupons surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities and Coupons so delivered shall be promptly cancelled by the Trustee. No Securities or Coupons shall be authenticated in lieu of or in exchange for any Securities or Coupons cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities and Coupons held by the Trustee shall be destroyed by the Trustee, unless by a Company Order the Company directs their return to it, and a certificate evidencing such destruction shall be delivered to the Company.

SECTION 310. Computation of Interest.

Except as otherwise specified as contemplated by
Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

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.

"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 <PAGE 37>

If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 331/3% 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 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:

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 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 premium, 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 reasonable 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,

(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 <PAGE 42>

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, 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; <PAGE 43>

(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.

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 <PAGE 44>

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.

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.
<PAGE 45>

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 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.

For purposes of this Section 515, "Conversion Rate" shall mean the spot rate as determined by the Company at which in accordance with normal banking procedures the currency or currency unit into which an amount due hereunder or under any Security or Coupon is to be converted could be purchased with the currency or currency unit due hereunder or under any Security or Coupon, at the option of the Company from major banks located in New York, London or any other principal market for such purchased currency or currency unit. <PAGE 46>

The obligations of the Company under this Section 605 to compensate and indemnify the Trustee and to pay or reimburse the Trustee and each predecessor Trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture.

SECTION 606. Resignation and Removal; Appointment of Successor.

(a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee pursuant to Section 607.

(3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the Trustee with respect to all Securities or the Securities of such series, or (ii) any Holder of a Security who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities of such series and the appointment of a successor Trustee or Trustees.

(e) if the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 607. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 607, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company.

SECTION 607. Acceptance of Appointment by Successor.

(a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties hereunder of the retiring Trustee; but, on the request of the Company or the successor Trustee, all property and Money held by such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and Money held by such retiring Trustee hereunder, subject nevertheless to its claim, if any, provided for in Section 605.

(b) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which

(c) Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be. <PAGE 51>

(d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under the Trust Indenture Act.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

SECTION 609. Corporate Trustee Required; Eligibility.

There shall at all times be a Trustee hereunder that is a Corporation permitted by the Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act and that has a combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

SECTION 610. Appointment of Authenticating Agent.

The Trustee may appoint one or more Authenticating Agents acceptable to the Company with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of that or those series issued upon original issue, exchange, registration of transfer, partial redemption or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent.

Each Authenticating Agent shall be acceptable to the Company and, except as provided in or pursuant to this Indenture, shall at all times be a corporation that would be permitted by the Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act, is authorized under applicable law and by its charter to act as an Authenticating Agent and has a combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Section. <PAGE 52>

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall (i) mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Registered Securities, if any, of the series with respect to which such Authenticating Agent shall serve, as their names and addresses appear in the Security Register, and (ii) if Securities of the series are issued as Bearer Securities, publish notice of such appointment at least once in an Authorized Newspaper in the place where such successor Authenticating Agent has its principal office if such office is located outside the United States. 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.

The Company agrees to pay each Authenticating Agent from time to time reasonable compensation for its services under this Section. If the Trustee makes such payments, it shall be entitled to be reimbursed for such payments, subject to the provisions of Section 605.

The provisions of Sections 308, 602 and 603 shall be applicable to each Authenticating Agent.

If an Authenticating Agent is appointed with respect to one or more series of Securities pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to or in lieu of the Trustee's certificate of authentication, an alternate certificate of authentication in the following form:

This is one of the Securities of the series designated herein referred to in the within-mentioned Indenture.

BANK ONE, NA

<PAGE 53>

If all of the Securities of any series may not be originally issued at one time, and if the Trustee does not have an office capable of authenticating Securities upon original issuance located in a Place of Payment where the Company wishes to have Securities of such series authenticated upon original issuance, the Trustee, if so requested in writing (which writing need not be accompanied by or contained in an Officers' Certificate by the Company), shall appoint in accordance with this
Section an Authenticating Agent having an office in a Place of Payment designated by the Company with respect to such series of Securities.

SECTION 611. Notice of Defaults.

The Trustee shall, within 90 days after the occurrence of a default with respect to the Securities of any series, mail to all Holders of Securities of that series entitled to receive reports pursuant to Section 703, notice of all defaults with respect to that series known to the Trustee, unless such defaults have been cured before the giving of such notice; provided, however, that, except in the case of default in the payment of the principal of, premium, if any, or interest on any of the Securities of such series or in the making of any sinking fund payment with respect to such series, the Trustee shall be protected in withholding such notice if and so long as the Board of Directors or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders of Securities of such series. For the purpose of this Section the term "default" means any event which is, or after notice or lapse of time or both would become, an Event of Default.

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 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.
<PAGE 61>

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 Chicago, Illinois or in the event that certificated senior notes are issued or if The Depositary Trust Company shall so require, the Company will be required to appoint a paying agent and security registrar in the City of New York 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 as Chicago, Illinois and initially appoints the office or agency of the Corporate Trust Office of the Trustee for such purpose. In the event that certificated senior notes are issued or if The Depositary Trust Company shall so require, the Company will appoint a paying agent and security registrar in the City of New York. Pursuant to
Section 301(6) of this Indenture, the Company may subsequently appoint a place or places in addition to or other than Chicago, Illinois 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 becoming 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, <PAGE 62>

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 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. <PAGE 63>

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 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.
<PAGE 64>

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.

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. Change of Control.

If this Section is specified, as contemplated by
Section 301, to be applicable to Securities and Coupons, if any, of any series, and if a Change of Control occurs and is accompanied by a Rating Decline (together, a "Change of Control Triggering Event"), each Holder of Securities of such series will have the right to require the Company to offer to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder's Securities at a purchase price in cash equal to the principal amount of such Securities plus accrued and unpaid interest, if any, to the date of purchase.

Within 30 days following any Change of Control Triggering Event, the Company will mail a notice (the "Change of Control Offer") to each Holder of Securities of such series with a copy to the Trustee stating:

(a) that a Change of Control Triggering Event has occurred and that such Holder has the right to require the Company to purchase such Holder's Securities at a purchase price in cash equal to the principal amount of such Securities plus accrued and unpaid interest, if any, to the date of purchase (the "Change of Control Payment");

(b) the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed) (the "Change of Control Payment Date"); and

(c) the procedures determined by the Company, consistent with the Indenture, that a Holder must follow in order to have its Securities repurchased.

On the Change of Control Payment Date with respect to the Securities of any series, the Company will, to the extent lawful:
<PAGE 68>

(a) accept for payment all Securities of such series or portions thereof (in integral multiples of $1,000) properly tendered and not withdrawn under the Change of Control Offer;

(b) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Securities of such series or portions thereof so tendered; and

(c) deliver or cause to be delivered to the Trustee the Securities of such series so accepted together with an Officers' Certificate stating the aggregate principal amount of such Securities or portions thereof being purchased by the Company.

The Paying Agent will promptly mail to each Holder of Securities of any series so tendered the Change of Control Payment for such Securities, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any; provided that each such new Security will be in a principal amount of $1,000 or an integral multiple of $1,000.

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender pursuant to the Change of Control Offer.

Prior to mailing a Change of Control Offer, and as a condition to such mailing (i) the requisite Holders of each issue of Indebtedness issued under any indenture or other agreement that may be violated by such payment shall have consented to such Change of Control Offer being made and waived the event of default, if any, caused by the Change of Control Triggering Event or (ii) the Company will repay all outstanding Indebtedness issued under any indenture or other agreement that may be violated by a payment to the Holders of Securities under a Change of Control Offer or the Company must offer to repay all such Indebtedness, and make payment to the holders of such Indebtedness that accept such offer and obtain waivers of any event of default from the remaining holders of such Indebtedness. The Company covenants to effect such repayment or obtain such consent and waiver within 30 days following any Change of Control Triggering Event, it being an Event of Default if the Company fails to comply with such covenant within 30 days after receipt of written notice from the Trustee or the Holders of at least 25% in principal amount of the Securities of any series.

The Company will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth herein applicable to a Change of Control Offer made by the Company and purchases all Securities validly tendered and not withdrawn under such Change of Control Offer.

SECTION 1008. 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 <PAGE 69>

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 1009. 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 is 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.

(b) The Company shall deliver to the Trustee, within five days after the occurrence thereof, written notice of any event which after notice or lapse of time or both would become an Event of Default.

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.

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 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.

fixed for redemption shall be void, that any interest accrued to the Redemption Date will be paid as specified in such notice, and that on and after such 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.

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 such 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 <PAGE 72>

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.

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.

This is one of the Securities of the series designated herein referred to in the within-mentioned Indenture.

BANK ONE, NA
as Trustee

By: ________________________________
Authorized Signatory

(REVERSE OF SECURITY)

This Security is one of a duly authorized issue of debt securities of the Company (herein called the "Securities"), issued and to be issued in one or more series under an Indenture, dated as of March 1, 2001 (herein called the "Indenture", which term shall have the meaning assigned to it in such instrument), between the Company and Bank One, NA, as trustee (herein called the "Trustee", which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture and all indentures supplemental thereto for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $150,000,000.

The Securities of this series are subject to redemption upon not less than 30 nor more than 60 days' notice by first-class mail, at any time, as a whole or in part, at the election of the Company, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities of this series to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities of this series to be redeemed (not including any portion of such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points, plus, in each case, accrued and unpaid interest on the principal amount of the Securities of this series being redeemed to the Redemption Date; provided that interest payments due on or prior to the Redemption Date will be paid to the record holders of such Securities on the relevant record date. As used herein the following terms will have the definitions given below:

"Treasury Rate" means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

"Comparable Treasury Issue" means the United States Treasury security or securities selected by an Independent Investment Banker as having a maturity or interpolated (on a day count basis) comparable to the remaining term of the Securities of this series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of the Securities.

"Independent Investment Banker" means one of the Reference Treasury Dealers appointed by the Trustee after consultation with the Company.

"Comparable Treasury Price" means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

"Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 3:30 p.m. New York time on the third business day in The City of New York preceding such Redemption Date.

"Reference Treasury Dealer" means at least five primary U.S. Government securities dealers in The City of New York as the Company shall select.

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

There is no sinking fund or mandatory redemption obligation applicable to the Securities of this series.

If a Change of Control occurs and is accompanied by a Rating Decline (together, a "Change of Control Triggering Event"), the Holder will have the right to require the Company to offer to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder's Securities of this series at a purchase price in cash equal to the principal amount of such Securities plus accrued and unpaid interest, if any, to the date of purchase. Within 30 days following any Change of Control Triggering Event, the Company will mail the Change of Control Offer to each registered Holder with a copy to the Trustee. No earlier than 30 days nor later than 60 days from the date such Change of Control Offer is mailed (the "Change of Control Payment Date"), the Company will, to the extent lawful, (i) accept for payment all Securities of this series or portions thereof (in integral multiples of $1,000) properly tendered and not withdrawn under the Change of Control Offer, (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities of this series or portions thereof so tendered, and (iii) deliver or cause to be delivered to the Trustee the Securities of this series so accepted together with an Officers' Certificate stating the aggregate principal amount of such Securities or portions thereof being purchased by the Company.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal amount of the Securities of this series may be declared due and payable in the manner and with the effect and subject to the conditions provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
