Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are received by a Responsible Officer of the Trustee and, where it is hereby expressly required, by the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee, the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section.

     (4) The ownership, principal amount and serial numbers of Bearer Securities held by any Person, and the date of the commencement and the date of the 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 Company and 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 (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.

     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, with a copy to The Bank of New York Mellon, 101 Barclay Street, Floor 8 West, New York, New York 10286, Attention: Corporate Trust Administration, 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, 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 in the first paragraph of this instrument 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 or the related Series Authorization, 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 in writing 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 which 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 filed in writing with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

     Section 1.7. 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 (with an accompanying English translation).

     Section 1.8. Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with any duties under any required provision of the Trust Indenture Act imposed hereon by Section 318(c) thereof, such required provision shall control.

interest shall accrue on the amount payable on such date or at such time for the period from and after such Interest Payment Date, Stated Maturity, Maturity or last day for conversion or exchange, as the case may be, to such next succeeding Business Day.

For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal holiday in The City of New York or a day on which banking institutions in The City of New York are authorized or obligated by law, regulation or executive order to be closed.

     Subject to the provisions of Section 6.6, nothing in this Indenture or in any Securities, express or implied, shall be construed to constitute a security interest under the Uniform Commercial Code or similar legislation, as now or hereafter enacted and in effect in any jurisdiction where property of the Company or its Subsidiaries is or may be located.

     (17) whether the amount of payments of principal of, any premium or interest on or any Additional Amounts with respect to such Securities may be determined with reference to an index, formula or other method or methods (which index, formula or method or methods may be based, without limitation, on one or more Currencies, commodities, equity securities, equity indices or other indices), and, if so, the terms and conditions upon which and the manner in which such amounts shall be determined and paid or payable;

The terms of the Securities of any series may provide, without limitation, that the Securities shall be authenticated and delivered by the Trustee on original issue from time to time upon written order of persons designated in the Officers’ Certificate or supplemental indenture and that such persons are authorized to determine, consistent with such Officers’ Certificate or any applicable supplemental indenture, such terms and conditions of the Securities of such series as are specified in such Officers’ Certificate or supplemental indenture. All Securities of any one series need not be issued at the same time and, unless otherwise so provided, a series may be reopened for issuances of additional Securities of such series or to establish additional terms of such series of Securities.

     Section 3.2. Currency; Denominations.

     Unless otherwise provided in or pursuant to this Indenture or the related Series Authorization, the principal of, any premium and interest on and any Additional Amounts with respect to the Securities shall be payable in Dollars.

Securities not denominated in Dollars shall be issuable in such denominations as are established with respect to such Securities in or pursuant to this Indenture or the related Series Authorization.

     Section 3.3. Execution, Authentication, Delivery and Dating.

     Securities shall be executed on behalf of the Company by an Authorized Officer and attested by a different Authorized Officer. Coupons shall be executed on behalf of the Company

by the Chief Financial Officer or Chief Accounting Officer 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 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 receive, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in, and may conclusively rely upon,

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

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

     (b) all conditions precedent to the authentication and delivery of such Securities and Coupons, if any, appertaining thereto, have been complied with and that such Securities and Coupons, when completed by appropriate insertions, executed and attested by duly authorized officers of the Company, delivered by duly authorized officers of the Company to the Trustee for authentication pursuant to this Indenture, and authenticated and delivered by the Trustee 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 against the Company in accordance with their terms, except as enforcement thereof may be subject to or limited by bankruptcy, insolvency, reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent transfer or other similar laws relating to or affecting creditors’ rights generally, and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law) and will entitle the Holders thereof to the benefits of this Indenture; such Opinion of Counsel need express no opinion as to the availability of equitable remedies;

     (c) all laws and requirements in respect of the execution and delivery by the Company of such Securities and Coupons, if any, have been complied with; and

     (d) this Indenture has been qualified under the Trust Indenture Act; and

     (2) an Officers’ Certificate stating that all conditions precedent to the execution, authentication and delivery of such Securities and Coupons, if any, appertaining thereto, have been complied with and that, 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 not be required to authenticate or to cause an Authenticating Agent to authenticate any Securities, nor will it be liable for its refusal to authenticate or cause an Authenticating Agent to authenticate any Securities, if the issue of such Securities 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 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 the related Series Authorization.

     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 Section 6.11 executed 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 or Section 3.7, 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 or the related Series Authorization, 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 upon Company Order shall authenticate and deliver in exchange therefor a like 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 or the related Series Authorization, 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 or the related Series Authorization. Unless otherwise provided in or pursuant to this Indenture or the related Series Authorization 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 related Series Authorization, 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 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. 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 or the related Series Authorization, 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 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 which the Holder making the exchange is entitled to receive.

     If provided in or pursuant to this Indenture or the related Series Authorization, 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 or the related Series Authorization 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 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 or the related Series Authorization, 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 or the related Series Authorization.

     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 which the Holder making the exchange is entitled to receive.

     Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture or the related Series Authorization, any global Security shall be exchangeable for definitive 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 executes and delivers

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 with respect to the 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 or the related Series Authorization, 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 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 or the related Series Authorization) 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 no such exchanges may occur during a period beginning at the opening of business 15 days before selection of Securities of the same series to be redeemed and ending on the relevant Redemption Date; and provided, further, that (unless otherwise provided in or pursuant to this Indenture or the related Series Authorization) 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 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 tax or other governmental charge and any other 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, Section 9.5 or Section 11.7 not involving any transfer.

     Except as otherwise provided in or pursuant to this Indenture or the related Series Authorization, the Company shall not be required (i) to issue, register the transfer of or exchange any Securities during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of Securities of like tenor and the same series under Section 11.4 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or exchange any Registered 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.

     Each Holder of a Security agrees to indemnify the Company and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Security in violation of any provision of this Indenture and/or applicable United States Federal or state securities law.

     The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among beneficial owners of interests in any global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

     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 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 protected purchaser, the Company shall execute and, upon the Company’s request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security or in exchange for the Security to which a destroyed, lost or stolen Coupon appertains with all appurtenant Coupons not destroyed, lost or stolen, 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 such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen Coupon appertains.

     Notwithstanding the foregoing provisions of this Section 3.6, in case any 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, pay such Security or Coupon; provided, however, that payment of principal of, any premium or interest on or any Additional Amounts with respect to any Bearer Securities shall, except as otherwise provided in Section 10.2, be payable only at an Office or Agency for such Securities located outside the United States and, unless otherwise provided in or pursuant to this Indenture or the related Series Authorization, any interest on Bearer Securities and any Additional Amounts with respect to such interest shall be payable only upon presentation and surrender of the Coupons appertaining thereto.

     Upon the issuance of any new Security under this Section 3.6, 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 and the fees and expenses of the Trustee’s counsel) connected therewith.

     Every new Security, with any Coupons appertaining thereto issued pursuant to this Section 3.6 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 a separate obligation of the Company, whether or not the destroyed, lost or stolen Security and Coupons appertaining thereto or the destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and shall be entitled to all of the benefits of this Indenture equally and proportionately with any and all other Securities of such series and any Coupons, if any, duly issued hereunder.

     The provisions of this Section 3.6, as amended or supplemented pursuant to this Indenture with respect to particular Securities or generally, shall be 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 3.7. Payment of Interest and Certain Additional Amounts; Rights to Interest and Certain Additional Amounts Preserved.

     Unless otherwise provided in or pursuant to this Indenture or the related Series Authorization, any interest on and any Additional Amounts with respect to any Registered Security which shall be payable, and are punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more Predecessor Securities) is registered as of the close of business on the Regular Record Date for such interest.

     Unless otherwise provided in or pursuant to this Indenture or the related Series Authorization, any interest on and any Additional Amounts with respect to any Registered Security which shall be payable, but shall not be punctually paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder thereof 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 Person in whose name such Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed by the Company in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on such Registered Security, the Special Record Date therefor and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when so deposited to be held in trust in a segregated trust account pursuant to express written instructions of the Company for the benefit of the Person entitled to such Defaulted Interest as in this Clause provided. The Special Record Date for the payment of such Defaulted Interest 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 notification to the Trustee of the proposed payment. The Trustee shall, in the name and at the expense of the Company, cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to the Holder of such Registered Security (or a Predecessor Security thereof) at his address as it appears in the Security Register not less than 10 days prior to such Special Record Date. The Trustee shall, 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 mailed as aforesaid, such Defaulted Interest shall be paid to the Person in whose name such Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

     (2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Security may be listed, and upon such notice as may be required by such exchange, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such payment shall be deemed practicable by the Trustee.

     Unless otherwise provided in or pursuant to this Indenture or the related Series Authorization of any particular series pursuant to the provisions of this Indenture, at the option of the Company, interest on Registered Securities that bear interest may be paid by mailing a check to the address of the Person entitled thereto as such address shall appear in the Security Register or by wire transfer to an account maintained by the payee with a bank located in the United States.

     Subject to the foregoing provisions of this Section and Section 3.5, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

     In the case of any Registered Security of any series that is convertible into shares of Common Stock of the Company or exchangeable for other securities, which Registered Security is converted or exchanged after any Regular Record Date and on or prior to the next succeeding Interest Payment Date (other than any Registered Security with respect to which the Stated Maturity is prior to such Interest Payment Date), interest with respect to which the Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion or exchange, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Registered Security (or one or more predecessor Registered Securities) is registered at the close of business on such Regular Record Date.

     Section 4.2. Defeasance and Covenant Defeasance.

     (1) Unless pursuant to Section 3.1, either or both of (i) defeasance of the Securities of or within a series under clause (2) of this Section 4.2 shall not be applicable with respect to the Securities of such series or (ii) covenant defeasance of the Securities of or within a series under clause (3) of this Section 4.2 shall not be applicable with respect to the Securities of such series, then such provisions, together with the other provisions of this Section 4.2 (with such modifications thereto as may be specified pursuant to Section 3.1 with respect to any Securities), shall be applicable to such Securities and any Coupons appertaining thereto, and the Company may at its option by Board Resolution, at any time, with respect to such Securities and any Coupons appertaining thereto, elect to have Section 4.2(2) or Section 4.2(3) be applied to such Outstanding Securities and any Coupons appertaining thereto upon compliance with the conditions set forth below in this Section 4.2.

     (2) Upon the Company’s exercise of the above option applicable to this Section 4.2(2) with respect to any Securities of or within a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities and any Coupons appertaining thereto on the date the conditions set forth in clause (4) of this

Section 4.2 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by such Outstanding Securities and any Coupons appertaining thereto, which shall thereafter be deemed to be “Outstanding” only for the purposes of clause (5) of this Section 4.2 and the other Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all of its other obligations under such Securities and any Coupons appertaining thereto, and this Indenture insofar as such Securities and any Coupons appertaining thereto are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of such Outstanding Securities and any Coupons appertaining thereto to receive, solely from the trust fund described in clause (4) of this Section 4.2 and as more fully set forth in such clause, payments in respect of the principal of (and premium, if any) and interest, if any, on, and Additional Amounts, if any, with respect to, such Securities and any Coupons appertaining thereto when such payments are due, and any rights of such Holder to convert such Securities into Common Stock of the Company or exchange such Securities for other securities, (ii) the obligations of the Company and the Trustee with respect to such Securities under Sections 3.5, 3.6, 10.2 and 10.3 and with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 10.4 (but only to the extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 4.2(4)(a) below), and with respect to any rights to convert such Securities into Common Stock of the Company or exchange such Securities for other securities, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder including, without limitation, the compensation, reimbursement and indemnities provided in Section 6.6 herein and (iv) this Section 4.2. The Company may exercise its option under this Section 4.2(2) notwithstanding the prior exercise of its option under clause (3) of this Section 4.2 with respect to such Securities and any Coupons appertaining thereto.

     (3) Upon the Company’s exercise of the option to have this Section 4.2(3) apply with respect to any Securities of or within a series, the Company shall be released from its obligations under Section 10.5 and Section 10.6, and any covenant applicable to such Securities specified in Section 3.1(19), including any obligation to redeem or repurchase such securities at the option of the Holder thereof, with respect to such Outstanding Securities and any Coupons appertaining thereto on and after the date the conditions set forth in clause (4) of this Section 4.2 are satisfied (hereinafter, “covenant defeasance”), and such Securities and any Coupons appertaining thereto shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with any such covenant or obligation, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities and any Coupons appertaining thereto, the Company may omit to comply with, and shall have no liability in respect of, any term, condition or limitation set forth in any such Section or such other covenant or obligation, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or obligation or by reason of reference in any such Section or such other covenant to any other provision herein or in any other document and such omission to comply shall not constitute a default

or an Event of Default under Section 5.1 but, except as specified above, the remainder of this Indenture and such Securities and Coupons appertaining thereto shall be unaffected thereby.

     (4) The following shall be the conditions to application of clause (2) or (3) of this Section 4.2 to any Outstanding Securities of or within a series and any Coupons appertaining thereto:

     (a) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 6.7 who shall agree to comply with the provisions of this Section 4.2 applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities and any Coupons appertaining thereto, (1) an amount in Dollars or in such Foreign Currency in which such Securities and any Coupons appertaining thereto are then specified as payable at Stated Maturity, or (2) Government Obligations applicable to such Securities and Coupons appertaining thereto (determined on the basis of the Currency in which such Securities and Coupons appertaining thereto are then specified as payable at Stated Maturity) which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment with respect to such Securities and any Coupons appertaining thereto, money in an amount, or (3) a combination thereof, in any case, in an amount, sufficient, without consideration of any reinvestment of such principal and interest, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (y) the principal of (and premium, if any) and interest, if any, on, and any Additional Amounts with respect to such Securities and Coupons appertaining thereto (based upon applicable law as in effect on the date of such deposit), such Outstanding Securities and any Coupons appertaining thereto at the Stated Maturity or Redemption Date of such principal or installment of principal or premium or interest and (z) any mandatory sinking fund payments or analogous payments applicable to such Outstanding Securities and any Coupons appertaining thereto on the days on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities and any Coupons appertaining thereto and, if applicable, shall have made irrevocable arrangements satisfactory to the Trustee for the redemption of any Securities to be redeemed at the option of the Company in connection with such deposit.

     (b) No Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect to such Securities and any Coupons appertaining thereto shall have occurred and be continuing on the date of such deposit (after giving effect thereto) and, with respect to defeasance only, no event described in Section 5.1(7) or (8) shall have occurred at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

     (c) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company is a party or by which it is bound.

     (d) In the case of an election under clause (2) of this Section 4.2 with respect to Registered Securities and any Bearer Securities for which the Place of Payment is within the United States, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from the Internal Revenue Service a letter ruling, or there has been published by the Internal Revenue Service a Revenue Ruling, or (ii) since the date of execution of this Indenture, there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred.

     (e) In the case of an election under clause (3) of this Section 4.2 with respect to Registered Securities and any Bearer Securities for which the Place of Payment is within the United States, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

     (f) With respect to defeasance only, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that, after the 91st day after the date of deposit, all money and Government Obligations (or other property as may be provided pursuant to Section 3.1) (including the proceeds thereof) deposited or caused to be deposited with the Trustee (or other qualifying trustee) pursuant to this clause (4) to be held in trust will not be subject to recapture or avoidance as a preference in any case or proceeding (whether voluntary or involuntary) in respect of the Company under any Federal or State bankruptcy, insolvency, reorganization or other similar law, or any decree or order for relief in respect of the Company issued in connection therewith (for which purpose such Opinion of Counsel may assume that no Holder is an “insider”).

     (g) With respect to defeasance only, the Company shall have delivered to the Trustee an Officers’ Certificate as to solvency and the absence of any intent of preferring the Holders over any other creditors of the Company.

     (h) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance or covenant defeasance under clause (2) or (3) of this Section 4.2 (as the case may be) have been complied with.

     (i) Notwithstanding any other provisions of this Section 4.2(4), such defeasance or covenant defeasance shall be effected in compliance with any additional or substitute terms, conditions or limitations which may be imposed on the Company in connection therewith pursuant to Section 3.1.

     (5) Unless otherwise specified in or pursuant to this Indenture or any Series Authorization, if, after a deposit referred to in Section 4.2(4)(a) has been made, (a) the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 3.1 or the terms of such Security to receive payment in a Currency other than that in which the deposit pursuant to Section 4.2(4)(a) has been made in respect of such Security, or (b) a Conversion Event occurs in respect of the Foreign Currency in which the deposit pursuant to Section 4.2(4)(a) has been made, the indebtedness represented by such Security and any Coupons appertaining thereto shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium, if any), and interest, if any, on, and Additional Amounts, if any, with respect to, such Security as the same becomes due out of the proceeds yielded by converting (from time to time as specified below in the case of any such election) the amount or other property deposited in respect of such Security into the Currency in which such Security becomes payable as a result of such election or Conversion Event based on (x) in the case of payments made pursuant to clause (a) above, the applicable market exchange rate for such Currency in effect on the second Business Day prior to each payment date, or (y) with respect to a Conversion Event, the applicable market exchange rate for such Foreign Currency in effect (as nearly as feasible) at the time of the Conversion Event.

     The Company shall pay and indemnify the Trustee (or other qualifying trustee, collectively for purposes of this Section 4.2(5) and Section 4.3, the “Trustee”) against any tax, fee or other charge, imposed on or assessed against the Government Obligations deposited pursuant to this Section 4.2 or the principal or interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Outstanding Securities and any Coupons appertaining thereto.

     Anything in this Section 4.2 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in clause (4) of this Section 4.2 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a defeasance or covenant defeasance, as applicable, in accordance with this Section 4.2.

     Section 4.3. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 10.3, all money and Government Obligations (or other property as may be provided pursuant to Section 3.1) (including the proceeds thereof) deposited with the Trustee pursuant to Section 4.1 or Section 4.2 in respect of any Outstanding Securities of any series and any Coupons appertaining thereto shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities

and any Coupons appertaining thereto and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities and any Coupons appertaining thereto of all sums due and to become due thereon in respect of principal (and premium, if any) and interest and Additional Amounts, if any; but such money and Government Obligations need not be segregated from other funds except to the extent required by law.

     No such rescission shall affect any subsequent default or impair any right consequent thereon.

     Section 5.3. 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 any Coupon appertaining thereto when such interest or Additional Amounts shall have 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 any premium on any Security or any Additional Amounts with respect thereto at their Maturity,

the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities and any Coupons appertaining thereto, the whole amount of money then due and payable with respect to such Securities and any Coupons appertaining thereto, with interest upon the overdue principal, any premium and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installments of interest and Additional Amounts at the rate or rates borne by or provided for in such Securities, 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 and all other amounts due to the Trustee under Section 6.6.

     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 and any Coupons appertaining thereto by such appropriate judicial proceedings as the Trustee shall deem necessary to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or such Securities or in aid of the exercise of any power granted herein or therein, or to enforce any other proper remedy.

     Section 5.4. 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 of any series 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, to the extent permitted by applicable law by intervention in such proceeding or otherwise,

     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 3.6, no right or remedy herein conferred upon or reserved to the Trustee or to each and every Holder of a Security or a Coupon is intended to be exclusive of any other right or remedy, and every right and remedy, to the extent permitted by law, shall 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, to the extent permitted by law, prevent the concurrent assertion or employment of any other appropriate right or remedy.

     Section 5.11. Delay or Omission Not Waiver.

     (2) The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.9 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee with respect to such series.

(5) 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 or pursuant to a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of such 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 6.9. If, within one year after such resignation, removal or incapacity, or the occurrence of such vacancy, a successor Trustee with respect to the

Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

     (7) In no event shall any retiring Trustee be liable for the acts or omissions of any successor Trustee hereunder.

     Section 6.9. Acceptance of Appointment by Successor.

     (1) Upon the appointment hereunder of any successor Trustee with respect to all Securities, such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and 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 written request of the Company or such successor Trustee, such retiring Trustee, upon payment of its charges, shall execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and, subject to Section 10.3, 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 6.6.

     (2) Upon the appointment hereunder of any successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and such successor Trustee shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, such successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with

respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust, that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee and that no Trustee shall be responsible for any notice given to, or received by, or any act or failure to act on the part of any other Trustee hereunder, and, upon the execution and delivery of such supplemental indenture, the resignation or removal of the retiring Trustee shall become effective to the extent provided therein, such retiring Trustee shall have no further responsibility for the exercise of rights and powers or for the performance of the duties and obligations vested in the Trustee under this Indenture with respect to the Securities of that or those series to which the appointment of such successor Trustee relates other than as hereinafter expressly set forth, and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on written request of the Company or such successor Trustee, such retiring Trustee, upon payment of its charges with respect to the Securities of that or those series to which the appointment of such successor Trustee relates and subject to Section 10.3 shall duly assign, transfer and deliver to such successor Trustee, to the extent contemplated by such supplemental indenture, the property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, subject to its claim, if any, provided for in Section 6.6.

     (3) Upon request of any Person appointed hereunder as a 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 (1) or (2) of this Section, as the case may be.

     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, shall be the successor of the Trustee hereunder, 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 6.11. 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 partial repayment or pursuant to Section 3.6, 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.

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 6.6.

Any interest due on any Bearer Security on or before the Maturity thereof, and any Additional Amounts payable with respect to such interest, shall be payable only upon presentation and surrender of the Coupons appertaining thereto for such interest as they severally mature.

     Section 10.2. Maintenance of Office or Agency.

     The Company shall maintain in each Place of Payment for any series of Securities an Office or Agency where Securities of such series (but not Bearer Securities, except as otherwise provided below, unless such Place of Payment is located outside the United States) may be presented or surrendered for payment, where Securities of such series may be surrendered for registration of transfer or exchange, where Securities of such series that are convertible or exchangeable may be surrendered for conversion or exchange, and where notices and demands to or upon the Company in respect of the Securities of such series relating thereto and this Indenture may be served. If Securities of a series are issuable as Bearer Securities, the Company, except as otherwise permitted or required in or pursuant to this Indenture or the related Series Authorization shall maintain, subject to any laws or regulations applicable thereto, an Office or Agency in a Place of Payment for such series which is located outside the United States where Securities of such series and any Coupons appertaining thereto may be presented and surrendered for payment; provided, however, that if the Securities of such series are listed on The Stock Exchange of the United Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange or any other stock exchange located outside the United States and such stock exchange shall so require, the Company shall maintain a Paying Agent in London, Luxembourg or any other required city located outside the United States, as the case may be, so long as the Securities of such series are listed on such exchange. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of 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 or the related Series Authorization, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

     Except as otherwise permitted or required in or pursuant to this Indenture or the related Series Authorization, no payment of principal, premium, interest or Additional Amounts with respect to Bearer Securities shall be made at any Office or Agency in the United States or by check mailed to any address in the United States or by wire transfer to an account maintained with a bank located in the United States; provided, however, if amounts owing with respect to any Bearer Securities shall be payable in Dollars, payment of principal of, any premium or interest on and any Additional Amounts with respect to any such Security may be made at the Corporate Trust Office of the Trustee or any Office or Agency designated by the Company in the Borough of Manhattan, The City of New York, if (but only if) payment of the full amount of such principal, premium, interest or Additional Amounts at all offices outside the United States maintained for such 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 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 of any series for such purposes. The Company shall 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 or the related Series Authorization, the Company hereby designates as the Place of Payment for each series of Securities the Borough of Manhattan, The City of New York, and initially appoints the Corporate Trust Office of the Trustee as the Office or Agency of the Company in the Borough of Manhattan, The City of New York for such purpose. The Company may subsequently appoint a different Office or Agency in the Borough of Manhattan, The City of New York for the Securities of any series.

     Unless otherwise specified with respect to any Securities pursuant to Section 3.1, if and so long as the Securities of any series (i) are denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long as it is required under any other provision of this Indenture, then the Company will maintain with respect to each such series of Securities, or as so required, at least one exchange rate agent.

     Section 10.3. 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, any premium or interest on or Additional Amounts with respect to any of the Securities of such series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the currency or currencies, currency unit or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series) sufficient to pay the principal or any premium, 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 in writing 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 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 (in the currency or currencies, currency unit or units or composite currency or currencies described in the preceding paragraph) sufficient to pay the principal and any premium, interest or Additional Amounts so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee in writing 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, any premium or interest on or any Additional Amounts with respect to Securities of such 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 provided in or pursuant to this Indenture or the related Series Authorization;

     (2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of such series) in the making of any payment of principal of, any premium 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 terms 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 sums.

     Except as otherwise provided herein or pursuant hereto, 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, any premium or interest on or any Additional Amounts with respect to any Security of any series or any Coupon appertaining thereto and remaining unclaimed for two years after such principal or any such premium or interest or any such 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 or any Coupon appertaining thereto 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 trust 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, at the expense of the Company may 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, or both, 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 two years after such principal and or any premium or interest or Additional Amounts shall have become due and payable, any unclaimed balance of such money then remaining will be repaid to the Company.

     Section 10.4. Additional Amounts.

     If provided in or pursuant to the related Series Authorization with respect to Securities of any series, all payments of principal of and premium, if any, interest and any other amounts on, or in respect of, the Securities of such series or any Coupon appertaining thereto shall be made without withholding or deduction at source for, or on account of, any present or future taxes, fees, duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of (A) the jurisdiction in which the Company is then organized or any political subdivision or taxing authority thereof or therein, (B) the jurisdiction of the Company’s principal executive offices or any political subdivision or taxing authority thereof or therein or (C) the jurisdiction of organization of any guarantor of the Securities or any political subdivision or taxing authority thereof or therein (each of clause (A), (B) and (C), a “taxing jurisdiction”), unless such taxes, fees, duties, assessments or governmental charges are required to be withheld or deducted by (i) the laws (or any regulations or ruling promulgated thereunder) of a taxing jurisdiction or any political subdivision or taxing authority thereof or therein or (ii) an official position regarding the application, administration, interpretation or enforcement of any such laws, regulations or rulings (including, without limitation, a holding by a court of competent jurisdiction or by a taxing authority in a taxing jurisdiction or any political subdivision thereof). If a withholding or deduction at source is required, the Company shall, subject to certain limitations and exceptions set forth below, pay to the Holder of any such Security or any Coupon appertaining thereto such Additional Amounts as may be necessary so that every net payment of principal, premium, if any, interest or any other amount made to such Holder, after such withholding or deduction, shall not be less than the amount provided for in such Security, any Coupons appertaining thereto and this Indenture to be then due and payable; provided, however, that the Company shall not be required to make payment of such Additional Amounts for or on account of:

     (1) any tax, fee, duty, assessment or governmental charge of whatever nature which would not have been imposed but for the fact that such Holder: (A) was a resident, domiciliary or national of, or engaged in business or maintained a permanent establishment or was physically present in, the relevant taxing jurisdiction or any political subdivision thereof or otherwise had some connection with the relevant taxing jurisdiction other than by reason of the mere ownership of, or receipt of payment under, such Security; (B) presented such Security for payment in the relevant taxing jurisdiction or any political subdivision thereof, unless such Security could not have been presented for payment elsewhere; or (C) presented such Security more than thirty (30) days after the date on which the payment in respect of such Security first became due and payable or provided for, whichever is later, except to the extent that the Holder would have been entitled to such Additional Amounts if it had presented such Security for payment on any day within such period of thirty (30) days;

     (2) any estate, inheritance, gift, sale, transfer, personal property or similar tax, assessment or other governmental charge;

     (3) any tax, assessment or other governmental charge that is imposed or withheld by reason of the failure by the Holder or the beneficial owner of such Security to comply with any reasonable request by the Company addressed to the Holder within 90 days of such request (A) to provide information concerning the nationality, residence or identity of the Holder or such beneficial owner or (B) to make any declaration or other similar claim or satisfy any information or reporting requirement, which, in the case of (A) or (B), is required or imposed by statute, treaty, regulation or administrative practice of the relevant taxing jurisdiction or any political subdivision thereof as a precondition to exemption from all or part of such tax, assessment or other governmental charge; or

     (4) any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any payment of the principal of, or premium, if any, interest or any other amounts on, any such Security to any Holder who is a fiduciary or partnership or other than the sole beneficial owner of such Security to the extent such payment would be required by the laws of the relevant taxing jurisdiction (or any political subdivision or relevant taxing authority thereof or therein) to be included in the income for tax purposes of a beneficiary or partner or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such Additional Amounts had it been the Holder of the Security.

     Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium, interest or any other amounts 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 the payment of Additional Amounts in those provisions hereof where such express mention is not made.

     The Company shall pay any stamp, issue, registration, documentary, value added, excise, property or other similar taxes and duties (including interest and penalties) payable in respect of the creation, issue, offering or execution of the Securities or any guarantee of the Securities, or any documentation with respect thereto, and will indemnify the Holders for any such taxes paid by the Holders.

     Except as otherwise provided in or pursuant to this Indenture or the related Series Authorization of the applicable series, 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 and premium, if any, interest or any other amounts on the Securities of such series shall be made to Holders of Securities of such series or the Coupons appertaining thereto without withholding for or on account of any tax, fee, duty, assessment or other governmental charge described in this Section 10.4. If any such withholding shall be required, then such Officers’ Certificate shall specify by taxing jurisdiction 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 this Section 10.4. 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 10.4.

     Section 10.5. Limitation on Liens on Stock of Designated Subsidiaries.

     So long as any Securities are Outstanding, the Company will not, nor will it permit any Subsidiary to, create, assume, incur, guarantee or otherwise permit to exist any Indebtedness secured by any mortgage, pledge, lien, security interest or other encumbrance (a “Lien”) upon any shares of Capital Stock of any Designated Subsidiary (whether such shares of stock are now owned or hereafter acquired) without effectively providing concurrently that the Securities (and, if the Company so elects, any other Indebtedness of the Company that is not subordinate to the Securities and with respect to which the governing instruments require, or pursuant to which the Company is otherwise obligated, to provide such security) shall be secured equally and ratably with such Indebtedness for at least the time period such other Indebtedness is so secured.

     Section 10.6. Limitation on Disposition of Stock of Designated Subsidiaries.

     So long as any Securities are outstanding and except in a transaction otherwise governed by this Indenture, the Company will not issue, sell, assign, transfer or otherwise dispose of any shares of, securities convertible into, or warrants, rights or options to subscribe for or purchase shares of, Capital Stock (other than Preferred Stock having no voting rights of any kind) of any Designated Subsidiary, and will not permit any Designated Subsidiary to issue (other than to the Company) any shares (other than the director’s qualifying shares) of, or securities convertible into, or warrants, rights or options to subscribe for or purchase shares of, Capital Stock (other than Preferred Stock having no voting rights of any kind) of any Designated Subsidiary, if, after giving effect to any such transaction and the issuance of the maximum number of shares issuable upon the conversion or exercise of all such convertible securities, warrants, rights or options, the Designated Subsidiary would remain a Subsidiary of the Company and the Company would own, directly or indirectly, less than 80% of the shares of Capital Stock of such Designated Subsidiary (other than Preferred Stock having no voting rights of any kind); provided, however, that (i) any issuance, sale, assignment, transfer or other disposition permitted by the Company may only be made for at least a fair market value consideration as determined by the Board of Directors pursuant to a Board Resolution adopted in good faith and (ii) the foregoing shall not prohibit any such issuance or disposition of securities if required by any law or any regulation or order of any governmental or insurance regulatory authority. Notwithstanding the foregoing, (i) the Company may merge or consolidate any Designated Subsidiary into or with another direct or indirect Subsidiary of the Company the shares of Capital Stock of which the Company owns at least 70%

and (ii) the Company may, subject to the provisions of Article 8, sell, assign, transfer or otherwise dispose of the entire Capital Stock of any Designated Subsidiary at one time for at least a fair market value consideration as determined by the Board of Directors pursuant to a Board Resolution adopted in good faith.

     Section 10.7. Corporate Existence.

     Subject to Article 8, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and rights (charter and statutory) and franchises; provided, however, that the foregoing shall not obligate the Company to preserve any such right or franchise if the Company shall determine that the preservation thereof is no longer desirable in the conduct of its business and that the loss thereof is not disadvantageous in any material respect to any Holder.

     Section 10.8. Waiver of Certain Covenants.

     The Company may omit in any particular instance to comply with any term, provision or condition set forth in Section 10.7 with respect to the Securities of any series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series, by Act of such Holders, either shall waive such compliance in such instance or generally shall have waived 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 10.9. Company’s Statement as to Compliance; Notice of Certain Defaults.

     (1) 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

     (a) a review of the activities of the Company during such year and of its performance under this Indenture has been made under his or her supervision, and

     (b) 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.

     (2) The Company shall deliver to the Trustee, within five days after the occurrence thereof, written notice of any Event of Default or any event which after notice

or lapse of time or both would become an Event of Default pursuant to clause (4) or (5) of Section 5.1.

     (3) The Trustee shall have no duty to monitor the Company’s compliance with the covenants contained in this Article 10 other than as specifically set forth in this Section 10.9.

     Section 10.10. Calculation of Original Issue Discount.

     The Company shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on any Outstanding Original Issue Discount Securities as of the end of such year and (ii) such other specific information relating to such original issue discount as may then be relevant under the Code, as amended from time to time.

Article 11

REDEMPTION OF SECURITIES

     Section 11.1. Applicability of Article.

     Redemption of Securities of any series as permitted or required by the terms of such Securities shall be made in accordance with the terms of such Securities and (except as otherwise provided herein or pursuant hereto) this Article.

     Section 11.2. Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of the Company of (a) less than all of the Securities of any series or (b) all of the Securities of any series, with the same issue date, interest rate or formula, Stated Maturity and other terms, 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 in writing of such Redemption Date and of the principal amount of Securities of such series to be redeemed.

     Section 11.3. Selection by Trustee of Securities to be Redeemed.

     If less than all of the Securities of any series with the same issue date, interest rate or formula, Stated Maturity and other terms are to be redeemed, the particular Securities to be redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate (including, without limitation, by lot or on a pro rata basis) and which may provide for the selection for redemption of portions of the principal amount of Registered Securities of such series; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Registered Security of such series not redeemed to less than the minimum denomination for a Security of such series established herein or pursuant hereto.

     The Trustee shall promptly notify the Company and the Security Registrar (if other than itself) in writing of the Securities 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 of such Securities which has been or is to be redeemed.

     Unless otherwise specified in or pursuant to this Indenture or the related Series Authorization of any series, if any Security selected for partial redemption is converted into Common Stock of the Company or exchanged for other securities in part before termination of the conversion or exchange right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted or exchanged during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection.

     Section 11.4. Notice of Redemption.

     Notice of redemption shall be given in the manner provided in Section 1.6, not less than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice by mailing in the manner herein provided to the Holder of any Registered Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Securities or portion thereof.

     Any notice that is mailed to the Holder of any Registered Securities in the manner herein provided shall be conclusively presumed to have been duly given, whether or not such Holder receives the notice.

     All notices of redemption shall state:

     (1) the Redemption Date, and if such redemption date is conditional, a description of the event upon which it is conditioned,

     (2) the Redemption Price,

     (3) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amount) of the particular Security or Securities to be redeemed,

     (4) in case any Security is to be redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder of such Security will receive, without charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed,

     (5) that, on the Redemption Date, the Redemption Price shall become due and payable upon each such Security or portion thereof to be redeemed, in the case of a Registered Security, together with any accrued interest and Additional Amounts pertaining thereto, and that unless the Company shall default in the payment of the Redemption Price and other amounts then due, interest thereon, if applicable, shall cease to accrue on and after said date,

     (6) the place or places where such Securities, together (in the case of Bearer Securities) with all Coupons appertaining thereto, if any, maturing on or after the Redemption Date, are to be surrendered for payment of the Redemption Price and any accrued interest and Additional Amounts pertaining thereto,

     (7) that the redemption is for a sinking fund, if such is the case,

     (8) that, unless otherwise specified in such notice, Bearer Securities of any series, if any, surrendered for redemption must be accompanied by all Coupons maturing subsequent to the date fixed for redemption or the amount of any such missing Coupon or Coupons will be deducted from the Redemption Price, unless security or indemnity satisfactory to the Company, the Trustee and any Paying Agent is furnished,

     (9) if Bearer Securities of any series are to be redeemed and no Registered Securities of such series are to be redeemed, and if such Bearer Securities may be exchanged for Registered Securities not subject to redemption on the Redemption Date pursuant to Section 3.5 or otherwise, the last date, as determined by the Company, on which such exchanges may be made,

     (10) in the case of Securities of any series that are convertible into Common Stock of the Company or exchangeable for other securities, the conversion or exchange price or rate, the date or dates on which the right to convert or exchange the principal of the Securities of such series to be redeemed will commence or terminate and the place or places where such Securities may be surrendered for conversion or exchange, and

     (11) the CUSIP number or the Euroclear or the Clearstream reference numbers of such Securities, if any (or any other numbers used by a Depository to identify such Securities).

     A notice of redemption published as contemplated by Section 1.6 need not identify particular Registered Securities to be redeemed.

     Notice of redemption of Securities shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company; provided in the latter case the Company will give the Trustee at least 5 days prior written notice of the date requested for the giving of said notice.

     Section 11.5. Deposit of Redemption Price.

     On or prior to any Redemption Date, the Company shall deposit, with respect to the Securities of any series called for redemption, with the Trustee or with a Paying Agent (or, if the

Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.3) an amount of money in the applicable Currency sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 3.1 or in the Securities of such series) any accrued interest on and Additional Amounts with respect thereto, all such Securities or portions thereof which are to be redeemed on that date.

     Section 11.6. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, become due and payable on the Redemption Date, 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 any accrued interest or Additional Amounts) 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. Upon surrender of any such Security for redemption in accordance with said notice, together with all Coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price, together with any accrued interest and Additional Amounts to the Redemption Date; provided, however, that, except as otherwise provided in or pursuant to the related Series Authorization and the Coupons, 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 10.2), and provided, further, that, except as otherwise specified in or pursuant to the related Series Authorization, installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the Regular Record Dates therefor according to their terms and the provisions of Section 3.7 and installments of interest on Registered Securities for which the Redemption Date is after a Regular Record Date and on or before the following Interest Payment 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 Regular Record Dates therefor according to their terms and the provisions of Section 3.7.

     If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant Coupons maturing after the Redemption Date, such 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 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 for such Security located outside of the United States except as otherwise provided in Section 10.2.

     If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium, until paid, shall bear interest from the Redemption Date at the rate prescribed therefor in the Security.

     Section 11.7. Securities Redeemed in Part.

     Any Registered Security which is to be redeemed only in part shall be surrendered at any Office or Agency for such Security (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 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 so surrendered. If a Security in global form is so surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to the U.S. Depository or other Depository for such Security in global form as shall be specified in the Company Order with respect thereto to the Trustee, without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Security in global form so surrendered.

Article 12

SINKING FUNDS

     Section 12.1. Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise permitted or required in or pursuant to this Indenture or the related Series Authorization.

     The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of such series is herein referred to as an “optional sinking fund payment”. If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 12.2. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series and this Indenture.

     Section 12.2. Satisfaction of Sinking Fund Payments with Securities.

     The Company may, in satisfaction of all or any part of any sinking fund payment with respect to the Securities of any series to be made pursuant to the terms of such Securities (1) deliver Outstanding Securities of such series (other than any of such Securities previously called for redemption or any of such Securities in respect of which cash shall have been released to the Company), together in the case of any Bearer Securities of such series with all unmatured Coupons appertaining thereto, and (2) apply as a credit Securities of such series which have been

redeemed either at the election of the Company pursuant to the terms of such series of Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, provided that such series of Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. If, as a result of the delivery or credit of Securities of any series in lieu of cash payments pursuant to this Section 12.2, the principal amount of Securities of such series to be redeemed in order to satisfy the remaining sinking fund payment shall be less than $100,000, the Trustee need not call Securities of such series for redemption, except upon Company Request, and such cash payment shall be held by the Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall at the written request of the Company from time to time pay over and deliver to the Company any cash payment so being held by the Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that series purchased by the Company having an unpaid principal amount equal to the cash payment requested to be released to the Company.

     Section 12.3. Redemption of Securities for Sinking Fund.

     Not less than 75 days prior to each sinking fund payment date for any series of Securities, the Company shall deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting of Securities of that series pursuant to Section 12.2, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities to be so credited and not theretofore delivered. If such Officers’ Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein specified. Not less than 60 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 11.3 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 11.4. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 11.6 and Section 11.7.

Article 13

REPAYMENT AT THE OPTION OF HOLDERS

     Section 13.1. Applicability of Article.

     Securities of any series which are repayable at the option of the Holders thereof before their Stated Maturity shall be repaid in accordance with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of Securities before their Stated Maturity, for purposes of Section 3.9, shall not operate as a payment, redemption or satisfaction of the Indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the

Trustee with a written directive that such Securities be cancelled. Notwithstanding anything to the contrary contained in this Section 13.1, in connection with any repayment of Securities, the Company may arrange for the purchase of any Securities by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to the Holders of such Securities on or before the close of business on the repayment date an amount not less than the repayment price payable by the Company on repayment of such Securities, and the obligation of the Company to pay the repayment price of such Securities shall be satisfied and discharged to the extent such payment is so paid by such purchasers.

Article 14

SECURITIES IN FOREIGN CURRENCIES

     Section 14.1. Applicability of Article.

     Whenever this Indenture provides for (i) any action by, or the determination of any of the rights of, Holders of Securities of any series in which not all of such Securities are denominated in the same Currency, or (ii) any distribution to Holders of Securities, in the absence of any provision to the contrary in the form of Security of any particular series or pursuant to this Indenture or the related Series Authorization, any amount in respect of any Security denominated in a Currency other than Dollars shall be treated for any such action or distribution as that amount of Dollars that could be obtained for such amount on such reasonable basis of exchange and as of the record date with respect to Registered Securities of such series (if any) for such action, determination of rights or distribution (or, if there shall be no applicable record date, such other date reasonably proximate to the date of such action, determination of rights or distribution) as the Company may specify in a written notice to the Trustee.
