12

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 (i) another certificate or affidavit bearing a later date issued in respect of the same Bearer Security is produced, or (ii) such Bearer Security is produced to the Trustee by some other Person, or (iii) such Bearer Security is surrendered in exchange for a Registered Security, or (iv) such Bearer Security is no longer Outstanding. The ownership, principal amount and serial numbers of Bearer Securities held by the Person so executing such instrument or writing and the date of the commencement and the date of the termination of holding the same may also be proved in any other manner, which the Company and the Trustee deem sufficient.

(5) 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 (but is not obligated to), by 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. 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 purpose 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 of Registered Securities 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.

(6) Any request, demand, authorization, direction, notice, consent, waiver or other Act by 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 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 Act is made upon such Security.

Section 1.5 Notices, etc. to Trustee and Company.

Any request, demand, authorization, direction, notice, consent, waiver or other Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

(1) the Trustee by any Holder or the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, or

(2) the Company, by the Trustee or any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed,

13

first-class postage prepaid, to the Company, addressed to the attention of its Treasurer, with a copy to the attention of its General Counsel, at the address of its principal office specified herein or at any other address previously furnished in writing to the Trustee by the Company.

Section 1.6 Notice to Holders of Securities; Waiver.

Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture provides for notice to Holders of Securities of any event,

(1) such notice shall be sufficiently given to Holders of Registered Securities if in writing and mailed, first-class postage prepaid, to each Holder of a Registered Security affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice; and

(2) such notice shall be sufficiently given to Holders of Bearer Securities, if any, if published in an Authorized Newspaper in The City of New York and, if such Securities are then listed on any stock exchange outside the United States, in an Authorized Newspaper in such city as the Company shall advise the Trustee that such stock exchange so requires, on a Business Day at least twice, the first such publication to be not earlier than the earliest date and the second such publication not later than the latest date prescribed for the giving of such notice.

In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to other Holders of Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as provided herein. Any notice that is mailed in the manner herein provided, shall be conclusively presumed to have been duly given or provided. In the 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 by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

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 Bearers Securities as provided above, then such notification to Holders of Bearer Securities as shall be given with the approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder. 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.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be

14

filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

All communications hereunder will be in writing and will be mailed, delivered or telegraphed and confirmed to the party receiving such communication at its address indicated below:

16

the Required Currency (i) shall not be discharged or satisfied by any tender, or any recovery pursuant to any judgment (whether or not entered in accordance with clause (a)), in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable and (iii) shall not be affected by judgment being obtained for any other sum due under this Indenture.

Section 3.3 Execution, Authentication, Delivery and Dating.

Securities shall be executed on behalf of the Company by its Chairman of the Board, a Vice Chairman, its President, its Chief Executive Officer, its Chief Financial Officer, its Treasurer or a Vice President under its corporate seal reproduced thereon and attested by its Secretary or one of its Assistant Secretaries. Coupons shall be executed on behalf of the Company by the Treasurer or any Assistant Treasurer of the Company. The signature of any of these officers on the Securities or any Coupons appertaining thereto may be manual or facsimile.

Securities and any Coupons appertaining thereto 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 or did not hold such offices at the date of original issuance of such Securities or Coupons.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities, together with any Coupons appertaining thereto, executed by the Company, to the Trustee for authentication and, provided that the Board Resolution and Officers’ Certificate or supplemental indenture or indentures with respect to such Securities referred to in Section 3.1 and a Company Order for the authentication and delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Company Order and subject to the provisions hereof and of such Securities shall authenticate and deliver such Securities. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities and any Coupons appertaining thereto, 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,

(1) an Opinion of Counsel to the effect that:

(a) the form or forms and the terms of such Securities and any Coupons have been established in conformity with the provisions of this Indenture; and

23

(b) such Securities, together with any Coupons appertaining thereto, when completed by appropriate insertions and executed and delivered by the Company to the Trustee for authentication in accordance with this Indenture, authenticated and delivered by the Trustee in accordance with this Indenture and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization and other similar laws of general applicability relating to or affecting the enforcement of creditors’ rights, to general equitable principles and to such other qualifications as such counsel shall conclude do not materially affect the rights of Holders of such Securities and any Coupons; and

(2) an Officers’ Certificate stating that, to the best knowledge of the Persons executing such certificate, all conditions precedent to the execution, authentication and delivery of such Securities and Coupons, if any, appertaining thereto, have been complied with, and 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.

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 of Counsel and Officers’ Certificate, with appropriate modifications, shall be delivered at or before the time of issuance of the first Security of such series. After any such first delivery, any separate written request by an Authorized Officer of the Company or any person designated in writing by an Authorized Officer that the Trustee authenticate and deliver Securities of such series for original issue will be deemed to be a certification by the Company that all conditions precedent provided for in this Indenture relating to authentication and delivery of such Securities continue to have been complied with and that no Event of Default with respect to any of the Securities has occurred or is continuing.

The Trustee shall not be required to authenticate or to cause an Authenticating Agent to authenticate any Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee or if the Trustee, being advised by counsel, determines that such action may not lawfully be taken.

Each Registered Security shall be dated the date of its authentication. Each Bearer Security and any Bearer Security in global form shall be dated as of the date specified in or pursuant to this Indenture.

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 in Section 2.2 or 6.11 executed

24

by or on behalf of the Trustee or by the Authenticating Agent by the manual signature of one of its authorized officers. Such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Except as permitted by Section 3.6, the Trustee shall not authenticate and deliver any Bearer Security unless all Coupons appertaining thereto then matured have been detached and cancelled.

Section 3.4 Temporary Securities.

Pending the preparation of definitive Securities, the Company may execute and deliver to the Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the manner provided in Section 3.3, temporary Securities in lieu thereof which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form or, if authorized in or pursuant to this Indenture, in bearer form with one or more Coupons or without Coupons and with such appropriate insertions, omissions, substitutions and other variations as the officers of the Company executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary Securities may be in global form.

Except in the case of temporary Securities in global form, which shall be exchanged in accordance with the provisions thereof, if temporary Securities are issued, the Company shall cause definitive Securities 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, such temporary Securities shall be exchangeable for such definitive Securities upon surrender of such temporary Securities at an Office or Agency for such Securities, without charge to any Holder thereof. Upon surrender for cancellation of any one or more temporary Securities (accompanied by any unmatured Coupons appertaining thereto), the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor an equal aggregate principal amount of definitive Securities of authorized denominations of the same series and containing identical terms and provisions; provided , however , that no definitive Bearer Security, except as provided in or pursuant to this Indenture, shall be delivered in exchange for a temporary Registered Security; and provided , further , that a definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the conditions set forth in or pursuant to this Indenture. Unless otherwise provided in or pursuant to this Indenture with respect to a temporary global Security, 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.

Section 3.5 Registration, Transfer and Exchange.

With respect to the Registered Securities of each series, if any, the Company shall cause to be kept a register (each such register being herein sometimes referred to as the “Security Register”) at an Office or Agency for such series in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of the Registered Securities of such series and of transfers of the Registered Securities of such series. Such Office or Agency shall be the “Security Registrar” for that series of Securities. Unless otherwise specified in or pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar for each series of Securities. The Company shall have the right to remove and replace from time to

25

time the Security Registrar for any series of Securities; provided that no such removal or replacement shall be effective until a successor Security Registrar with respect to such series of Securities shall have been appointed by the Company and shall have accepted such appointment by the Company. In the event that the Trustee shall not be or 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. The Company shall be required to maintain a Security Registrar in each place where the principal of and premium or interest on any Security is payable. There shall be only one Security Register for each series of Securities.

Upon surrender for registration of transfer of any Registered Security of any series at any Office or Agency for such 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 denominated as authorized in or pursuant to this Indenture, of a like aggregate principal amount bearing a number not contemporaneously outstanding and containing identical terms and provisions.

At the option of the Holder, certificated Securities (including Bearer Securities) and the right to receive the principal, premium and interest, if any, on any certificated Security may be transferred by a Holder by surrendering such certificate representing the certificated Securities at the Corporate Trust Office of the Trustee. Such certificate representing the certificated Securities may be reissued by the Company or the Trustee to a new Holder or a new certificate representing the certificated Securities may be issued by the Company or the Trustee to a new Holder.

At the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any Office or Agency for such series. Whenever any Registered Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Registered Securities that the Holder making the exchange is entitled to receive.

If provided in or pursuant to this Indenture, with respect to Securities of any series, at the option of the Holder, Bearer Securities of such series may be exchanged for Registered Securities of such series containing identical terms, denominated as authorized in or pursuant to this Indenture and in the same aggregate principal amount, upon surrender of the Bearer Securities to be exchanged at any Office or Agency for such series, 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 is 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 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

26

10.2, interest represented by Coupons shall be payable only upon presentation and surrender of those Coupons at an Office or Agency for such series located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such Office or Agency for such series in exchange for a Registered Security of such series and like tenor 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 next succeeding 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.

If provided in or pursuant to this Indenture with respect to Securities of any series, at the option of the Holder, Registered Securities of such series may be exchanged for Bearer Securities upon such terms and conditions as may be provided in or pursuant to this Indenture with respect to such series.

Whenever any Securities are surrendered for exchange as contemplated by the immediately preceding two paragraphs, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities that the Holder making the exchange is entitled to receive.

Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture, any global Security shall be exchangeable for certificated Securities only if (i) the Depository is at any time unwilling, unable or ineligible to continue as depository and a successor depository is not appointed by the Company within 90 days of the date the Company is so informed in writing, (ii) the Company, in its discretion, determines not to require all of the Securities of a series to be represented by a global Security and notifies the Trustee of its decision by executing and delivering to the Trustee a Company Order to the effect that such global Security shall be so exchangeable or (iii) an Event of Default has occurred and is continuing, the Company, the Trustee, the Registrar and the Paying Agent shall have notified the Depository that the global Security shall be exchangeable for certificated Securities. If the beneficial owners of interests in a global Security are entitled to exchange such interests for definitive Securities as the result of an event described in clause (i), (ii) or (iii) of the preceding sentence, then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities in such form and denominations as are required by or pursuant to this Indenture, and of the same series, containing identical terms and in aggregate principal amount equal to the principal amount of such global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such global Security shall be surrendered from time to time by the U.S. Depository or such other Depository as shall be specified in the Company Order with respect thereto, and in accordance with instructions given to the Trustee and the U.S. Depository or such other Depository, as the case may be (which instructions shall

27

be in writing but need not be contained in or accompanied by an Officers’ Certificate or be accompanied by an Opinion of Counsel), as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for definitive Securities as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered global Security, a like aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such global Security to be exchanged, which (unless such Securities are not issuable both as Bearer Securities and as Registered Securities, in which case the definitive Securities exchanged for the global Security shall be issuable only in the form in which the Securities are issuable, as provided in or pursuant to this Indenture) shall be in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall be specified by the beneficial owner thereof, but subject to the satisfaction of any certification or other requirements to the issuance of Bearer Securities; provided , however , that (unless otherwise provided in or pursuant to this Indenture) no Bearer Security delivered in exchange for a portion of a global Security shall be mailed or otherwise delivered to any location in the United States. Promptly following any such exchange in part, such global Security shall be returned by the Trustee to such Depository or the U.S. Depository, as the case may be, or such other Depository or U.S. Depository referred to above in accordance with the instructions of the Company referred to above. If a Registered Security is issued in exchange for any portion of a global Security after the close of business at the Office or Agency for such Security where such exchange occurs on or after (i) any Regular Record Date for such Security and before the opening of business at such Office or Agency on the next succeeding Interest Payment Date, or (ii) any Special Record Date for such Security and before the opening of business at such Office or Agency on the related proposed date for payment of interest or Defaulted Interest, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but shall be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such global Security shall be payable in accordance with the provisions of this Indenture.

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 for such Security) be duly endorsed, or be accompanied by a written instrument of transfer in a form satisfactory to the Company and the Security Registrar for such Security 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 stamp tax or other governmental charge and any other reasonable expenses (including fees and expenses of the Trustee) that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.4, 3.6, 9.5 or 11.7 not involving any transfer.

28

Except as otherwise provided in or pursuant to this Indenture, the Company shall not be required (i) to register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before the day the Company transmits a notice of redemption of Securities of the series selected for redemption and ending at the close of business on the day of the transmission, or (ii) to register the transfer of or exchange any Security selected for redemption in whole or in part, except in the case of any Security to be redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security selected for redemption except, to the extent provided with respect to such Bearer Security, that such Bearer Security may be exchanged for a Registered Security of like tenor and the same series, provided that such Registered Security shall be immediately 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 3.6 Mutilated, Destroyed, Lost and Stolen Securities.

If any mutilated Security or a Security with a mutilated Coupon appertaining to it is surrendered to the Trustee, subject to the provisions of this Section 3.6, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding, with Coupons appertaining thereto corresponding to the Coupons, if any, appertaining to the surrendered Security.

If there be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or Coupon, and (ii) such securi
