In the event of conversion of this Security in part only, a new Security or Securities for the unconverted portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof.] [IF THE SECURITY IS CONVERTIBLE INTO OTHER SECURITIES OF THE COMPANY, SPECIFY THE CONVERSION FEATURES.] [IF THE SECURITY IS NOT AN ORIGINAL ISSUE DISCOUNT SECURITY,--If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.] [IF THE SECURITY IS AN ORIGINAL ISSUE DISCOUNT SECURITY,--If an Event of Default with respect to Securities of this series shall occur and be continuing, an amount of principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 19 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Security at the times, place and [rate-rates], and in the coin or currency, herein prescribed.

EXECUTION, AUTHENTICATION, DELIVERY AND DATING. The Securities shall be executed on behalf of the Company by its Chairman of the Board, its President or one of its Vice Presidents, under its corporate seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities. If the form or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions as permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive at the time of the initial delivery by the Company of Securities of such series to the Trustee for authentication, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating, (a) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 201, that such form has been established in conformity with the provisions of this Indenture; (b) if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 301, that such terms have been established in conformity with the provisions of this Indenture; and (c) that such Securities (when executed by the Company, authenticated by the Trustee and delivered against payment therefor by the purchasers thereof) and the supplemental indenture, if any, (when executed and delivered by the Company and the Trustee), will constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, except to the extent that enforcement thereof may be limited by (1) bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to creditors' rights generally and (2) general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). After any such first delivery, any separate request by the Company that the Trustee authenticate Securities of such series for original issue will be deemed to be a certification by 26 the Company that all conditions precedent provided for in this Indenture relating to the authentication and delivery of such Securities continue to have been complied with. The Trustee may, but shall not be obligated to, authenticate the Securities of any series the form or terms of which have been so established and with respect to which it would not be or have been obligated, pursuant to the second sentence of Section 903, to execute, at the time such authentication is requested (if no Securities of such series have been authenticated) or at the time of the initial authentication of Securities of such series (if Securities of such series have been authenticated), an indenture supplemental hereto containing such form or terms. Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers' Certificate otherwise required pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the time of authentication of each Security of such series if such documents are delivered at or prior to the time of authentication upon original issuance of the first Security of such series to be issued. Each Security shall be dated the date of its authentication. No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309 together with a written statement (which need not comply with Section 102 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. SECTION 304. TEMPORARY SECURITIES. Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. 27 If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company designated pursuant to Section 1002 in a Place of Payment for Securities of that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like aggregate principal amount of definitive Securities of the same series and of like tenor of authorized denominations. 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 305. REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company maintained pursuant to Section 1002 for such purpose in a Place of Payment being herein sometimes collectively referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed "Security Registrar" for the purpose of registering Securities and transfers of Securities as herein provided. Upon surrender for registration of transfer of any Security of any series at the office or agency of the Company maintained pursuant to Section 1002 for such purpose in a Place of Payment for Securities of that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of like tenor of the same series, of any authorized denominations and of a like aggregate principal amount and tenor. At the option of the Holder, Securities of any series may be exchanged for other Securities of like tenor of the same series, of any authorized denominations and of a like aggregate principal amount and tenor, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a 28 written instrument of transfer in form satisfactory to the Company and the Security Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. The Company shall not be required (i) to issue, register the transfer of or exchange any Security of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities of such series selected for redemption under Section 1103 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. Notwithstanding the foregoing, any Global Security shall be exchangeable pursuant to this Section 305 for Securities registered in the names of Persons other than the Depositary for such Security or its nominee only if (i) such Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security or if at any time such Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, (ii) the Company executes and delivers to the Trustee a Company Order that such Global Security shall be so exchangeable or (iii) there shall have occurred and be continuing an Event of Default with respect to the Securities. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Securities registered in such names as such Depositary shall direct. Notwithstanding any other provision in this Indenture, a Global Security may not be transferred except as a whole by the Depositary with respect to such Global Security to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary. SECTION 306. MUTILATED, DESTROYED, LOST OR STOLEN SECURITIES. If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously Outstanding. If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its request the Trustee shall authenticate and 29 deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously Outstanding. In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security of the same series, pay such Security. Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED. Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below: (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the 30 Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date, and in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities of such series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). (2) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee. Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. Subject to the provisions of Section 1402, in the case of any Security which is converted after any Regular Record Date and on or prior to the next succeeding Interest Payment Date (other than any Security, the principal of (or premium, if any, on) which shall become due and payable, whether at a Stated Maturity or by declaration of acceleration, call for redemption, or otherwise, prior to such Interest Payment Date), interest whose Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Security which is converted, interest whose Stated Maturity is after the date of conversion of such Security shall not be payable. 31 SECTION 308. PERSONS DEEMED OWNERS. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 307) interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. SECTION 309. CANCELLATION. All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of as directed by a Company Order. SECTION 310. COMPUTATION OF INTEREST. Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

Unless otherwise specified as contemplated in Section 301 or in a supplemental indenture relating to the Securities of any series, "Event of Default", wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be occasioned by the provisions of Article Thirteen or be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): (1) default in the payment of any interest upon any Security of that series when it becomes due and payable, and continuance of such default for a period of 30 days; or (2) default in the payment of the principal of (or premium, if any, on) any Security of that series at its Maturity; or (3) default in the deposit of any sinking fund payment, when and as due by the terms of a Security of that series; or (4) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty, a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the benefit of Securities of any series other than that series), and continuance of such default or breach for a period of 60 days after there has 36 been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 10% in principal amount of the Outstanding Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or (5) there shall be a default (A) under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company (including a default with respect to the Securities of any series other than that series) or (B) under any mortgage, indenture or other instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company or any Restricted Subsidiary or (C) under any guarantee of payment by the Company or any Restricted Subsidiary of indebtedness for money borrowed, or (D) under any bond, debenture, note or other similar instrument (excluding trade accounts payable or accrued liabilities arising in the normal course of business which are not overdue by more than 90 days or which are being contested in good faith) of the Company or any Restricted Subsidiary whether such indebtedness or guarantee now exists or shall hereafter be incurred or created, and as a result of such default such indebtedness has, by acceleration or otherwise under the terms of such bond, debenture, note, mortgage, indenture, guarantee of payment or such other evidence of indebtedness, become due prior to its stated maturity; PROVIDED, HOWEVER, that a default under this Section 501(5) shall exist only if all such defaults relate to such indebtedness or such guarantees with an aggregate principal amount in excess of $5,000,000, the acceleration of which has not been rescinded or annulled within a period of ten days after there shall have been given, by registered or certified mail, notice thereof to the Company by the Trustee or to the Company and the Trustee by Holders of at least 25% in principal amount of the Securities of any series at that time Outstanding; PROVIDED, HOWEVER, that if such default under such indenture or instrument shall be remedied or cured by the Company, or waived by the Holders of such indebtedness, then the Event of Default hereunder by reason thereof shall be deemed likewise to have been thereupon remedied, cured or waived without further action upon the part of either the Trustee or any of the Holders of Securities of any series at that time Outstanding; and PROVIDED, FURTHER, that, subject to the provisions of Sections 601 and 602, the Trustee shall not be deemed to have knowledge of such default unless either (i) a Responsible Officer of the Trustee shall have actual knowledge of such default or (ii) the Trustee shall have received written notice thereof from the Company, from any Holder, from the holder of any such indebtedness or from the trustee under any such mortgage, indenture or other instrument; or (6) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company or any Restricted Subsidiary in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company or any Restricted Subsidiary a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company or 37 any Restricted Subsidiary under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or any Restricted Subsidiary or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; or (7) the commencement by the Company or any Restricted Subsidiary of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company or any Restricted Subsidiary in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or similar official of the Company or any Restricted Subsidiary or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any Restricted Subsidiary in furtherance of any such action; or (8) any other Event of Default provided, pursuant to Section 301, in or pursuant to a Board Resolution or indenture supplemental hereto as a part of the terms of and as applicable with respect to Securities of that series. Upon receipt by the Trustee of any notice with respect to a Default pursuant to this Section 501 with respect to Securities of a series all or part of which is represented by a Global Security, a record date shall be established for determining Holders of Outstanding Securities of such series entitled to join in the delivery of a Notice of Default, which record date shall be at the close of business on the day the Trustee receives such notice with respect to a Default. The Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to join in a Notice of Default, whether or not such Holders remain Holders after such record date; PROVIDED, that unless Holders of at least 10% in principal amount of the Outstanding Securities of such series, or their proxies, shall have joined in a Notice of Default prior to the day which is 90 days after such record date, such notice with respect to a Default shall automatically and without further action by any Holder be canceled and of no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from giving, after expiration of such 90-day period, a new notice with respect to a Default identical to a notice with respect to a Default which has been canceled pursuant to the proviso to the preceding sentence, in which event a new record date shall be established pursuant to the provisions of this Section 501. 38 SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT. If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount (or, if any of the Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such securities as may be specified in the terms thereof) of all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if (1) the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all overdue interest on all Securities of that series, (B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Securities, (C) all overdue sinking fund payments with respect to Securities of that series and interest thereon at the rate or rates prescribed therefor in such Securities, (D) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and (E) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and (2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. Upon receipt by the Trustee of written notice declaring an intention to accelerate, or rescind and annul an acceleration, with respect to Securities of a series all or part of which is 39 represented by a Global Security, a record date shall be established for determining Holders of Outstanding Securities of such series entitled to join in a notice of acceleration, or rescission and annulment thereof, which record date shall be at the close of business on the day the Trustee receives a notice of the intention to accelerate, or rescind and annul an acceleration. The Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to join in a notice of acceleration, or rescission and annulment thereof, whether or not such Holders remain Holders after such record date; PROVIDED, that unless such declaration of acceleration, or rescission and annulment, as the case may be, shall have become effective by virtue of the requisite percentage having joined in a notice of acceleration, or rescission and annulment thereof prior to the day which is 90 days after such record date, the notice of the intention to accelerate, or rescind and annul an acceleration, as the case may be, shall automatically and without further action by any Holder be canceled and of no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from giving, after expiration of such 90-day period, a new written notice of an intention to accelerate, or rescind and annul an acceleration, as the case may be, that is identical to a written notice which has been canceled pursuant to the proviso to the preceding sentence, in which event a new record date shall be established pursuant to the provisions of this Section 502. No such rescission shall affect any subsequent default or impair any right consequent thereon. SECTION 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE. The Company covenants that if (1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or (2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof, or (3) default is made in the deposit of any sinking fund payment, when and as due by the terms of a Security of any series, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holder of such Security, the whole amount then due and payable on such Security for principal (and premium, if any) and interest and for any sinking fund payment and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and on any overdue interest and on any overdue sinking fund payment, at the rate or rates prescribed therefor in such Security, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 40 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Security and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Security, wherever situated. If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. SECTION 504. TRUSTEE MAY FILE PROOFS OF CLAIM. In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 41 SECTION 506. APPLICATION OF MONEY COLLECTED. Subject to Article Thirteen are the provisions of any supplemented indenture, any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest or sinking fund payments, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: FIRST: To the payment of all amounts due the Trustee under Section 607; and SECOND: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on, and sinking fund payments with respect to, the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest and sinking fund payments, respectively. SECTION 507. LIMITATION ON SUITS. No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series; (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, 42 disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. Upon receipt by the Trustee of written request to the Trustee to institute proceedings in respect of a continuing Event of Default pursuant to Section 507(2) with respect to Securities of a series all or part of which is represented by a Global Security, a record date shall be established for determining Holders of Outstanding Securities of such series entitled to join in such written request in respect of such Event of Default, which record date shall be at the close of business on the day the Trustee receives a written request to institute such proceedings. The Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to join in a written request to institute proceedings, whether or not such Holders remain Holders after such record date; PROVIDED, that unless such written request shall have become effective by virtue of the requisite percentage having joined in such written request prior to the day which is 90 days after such record date, the written request shall automatically and without further action by any Holder be canceled and of no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from giving, after expiration of such 90-day period, a new written request to institute proceedings in respect of such continuing Event of Default, that is identical to a written notice which has been canceled pursuant to the proviso to the preceding sentence, in which event a new record date shall be established pursuant to the provisions of this Section 507. SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND INTEREST. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of (and premium, if any) and (subject to Section 307) any interest on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date), to convert such Securities in accordance with Article Fourteen and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. SECTION 509. RESTORATION OF RIGHTS AND REMEDIES. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 43 SECTION 510. RIGHTS AND REMEDIES CUMULATIVE. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. SECTION 511. DELAY OR OMISSION NOT WAIVER. No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. SECTION 512. CONTROL BY HOLDERS. The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, PROVIDED that (1) such direction shall not be in conflict with any rule of law or with this Indenture, and (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. Upon receipt by the Trustee of any written notice directing the time, method or place of conducting any such proceeding or exercising any such trust or power, with respect to Securities of a series all or part of which is represented by a Global Security, a record date shall be established for determining Holders of Outstanding Securities of such series entitled to join in such notice, which record date shall be at the close of business on the day the Trustee receives such notice. The Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to join in such notice, whether or not such Holders remain Holders after such record date; PROVIDED, that unless the Holders of a majority in principal amount of the Outstanding Securities of such series shall have joined in such notice prior to the day which is 90 days after such record date, such notice shall automatically and without further action by any 44 Holder be canceled and of no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from giving, after expiration of such 90-day period, a new notice identical to a notice which has been canceled pursuant to the proviso to the preceding sentence, in which event a new record date shall be established pursuant to the provisions of this Section 512. SECTION 513. WAIVER OF PAST DEFAULTS. The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to the Securities of such series and its consequences, except a default (1) in the payment of the principal of (or premium, if any) or interest on any Security of such series or in the payment of any sinking fund instalment with respect to the Securities of such series, or (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to waive any past default hereunder. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to waive any default hereunder, whether or not such Holders remain Holders after such record date; PROVIDED, that unless such majority in principal amount shall have waived such default prior to the date which is 90 days after such record date, any such waiver previously given shall automatically and without further action by any Holder be canceled and of no further effect. Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. SECTION 514. UNDERTAKING FOR COSTS. In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; PROVIDED that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in 45 any suit instituted by the Company or in any suit for the enforcement of the right to convert any Security in accordance with Article Fourteen. SECTION 515. WAIVER OF STAY OR EXTENSION LAWS.

ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. (a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. (b) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each 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 the Securities of all series for which it is the Trustee hereunder, 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 and 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 upon the execution and delivery of such supplemental indenture the resignation or 51 removal of the retiring Trustee shall become effective to the extent provided therein and each 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 request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all 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. (c) Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be. (d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. SECTION 612. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. SECTION 613. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor). SECTION 614. APPOINTMENT OF AUTHENTICATING AGENT. At any time when any of the Securities remain Outstanding the Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid 52 and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, as their names and addresses appear in the Security Register. 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 Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 607. 53 If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to the Trustee's certificate of authentication, an alternate certificate of authentication in the following form: This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

No provision in any supplemental indenture that affects the superior position of the holders of Senior Indebtedness shall be effective against holders of Senior Indebtedness. ARTICLE TEN COVENANTS SECTION 1001. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST. The Company covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay the principal of (and premium, if any) and interest on the Securities of that series in accordance with the terms of the Securities of such series and this Indenture. SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY. The Company will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange, where Securities of that series may be surrendered for conversion and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served, PROVIDED, HOWEVER, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. With respect to the Securities of any series, such office or agency and each Place of Payment shall be as specified as contemplated by Section 301. In the absence of any such provisions with respect to the Securities of any series, the Place of Payment for such Securities shall initially be the Corporate Trust Office. 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, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 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 will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 61 SECTION 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST. If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of (and premium, if any) or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, prior to each due date of the principal of (and premium, if any) or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held as provided by the Trust Indenture Act in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. The Company will 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 will: (1) hold all sums held by it for the payment of the principal of (and premium, if any) or interest on Securities of that series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; (2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment of principal (and premium, if any) or interest on the Securities of that series; and (3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest on any Security of any series and remaining unclaimed for two years after such principal (and premium, if any) or 62 interest has 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 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, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in the Borough of Manhattan, The City of New York, 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, any unclaimed balance of such money then remaining will be repaid to the Company. SECTION 1004. CORPORATE EXISTENCE. Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, rights (charter and statutory) and franchises; PROVIDED, HOWEVER, that the Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. SECTION 1005. PAYMENT OF TAXES AND OTHER CLAIMS. The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and (2) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any Subsidiary; PROVIDED, HOWEVER, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings. SECTION 1006. LIMITATION UPON SALES OF CAPITAL STOCK OF RESTRICTED SUBSIDIARIES. The Company will not sell, transfer or otherwise dispose of (except to a Restricted Subsidiary or for directors' qualifying shares), and it will not permit any Restricted Subsidiary to sell, transfer or otherwise dispose of (except to the Company or to a Restricted Subsidiary or for directors' qualifying shares) any shares of capital stock of a Restricted Subsidiary, unless the entire capital stock of such Restricted Subsidiary at the time owned by the Company and its Restricted Subsidiaries shall be disposed of at the same time for a consideration consisting of cash or other property, which, in the opinion of the Board of Directors, is at least equal to the fair value thereof. 63 SECTION 1007. LIMITATION UPON CREATION OF LIENS ON CAPITAL STOCK OF RESTRICTED SUBSIDIARIES. The Company will not, and it will not permit any Restricted Subsidiary at any time directly or indirectly to, create, assume, incur or permit to exist any indebtedness secured by a pledge, lien or other encumbrance on the capital stock of any Restricted Subsidiary without making effective provision whereby the Securities then outstanding (and, if the Company so elects, any other indebtedness ranking on a parity with the Securities) shall be equally and ratably secured with such secured indebtedness so long as such other indebtedness shall be secured. If the Company shall hereafter be required to secure the Securities equally and ratably with any other indebtedness pursuant to this Section, (i) the Company will promptly deliver to the Trustee an Officers' Certificate stating that the foregoing covenant has been complied with, and an Opinion of Counsel stating that in the opinion of such counsel the foregoing covenant has been complied with and that any instruments executed by the Company or any Restricted Subsidiary in the performance of the foregoing covenant comply with the requirements of the foregoing covenants and (ii) the Trustee is hereby authorized to enter into an indenture or agreement supplemental hereto and to take such action, if any, as it may deem advisable to enable it to enforce the rights of the holders of the Securities so secured. SECTION 1008. STATEMENT BY OFFICERS AS TO DEFAULT. The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers' Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of Sections 1001 to 1007, inclusive, and if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. SECTION 1009. WAIVER OF CERTAIN COVENANTS. The Company may omit in any particular instance to comply with any term, provision or condition set forth in Sections 1002 and 1004 to 1007, inclusive, with respect to the Securities of any series if before the time for such compliance the Holders of at least 66-2/3% in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to waive any such term, provision or condition. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only such 64 Persons, shall be entitled to waive any such term, provision or condition hereunder, whether or not such Holders remain Holders after such record date; PROVIDED, that unless the Holders of at least 66-2/3% in principal amount of the Outstanding Securities of such series shall have waived such term, provision or condition prior to the date which is 90 days after such record date, any such waiver previously given shall automatically and without further action by any Holder be canceled and of no further effect. ARTICLE ELEVEN REDEMPTION OF SECURITIES SECTION 1101. APPLICABILITY OF ARTICLE. Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for Securities of any series) in accordance with this Article. SECTION 1102. ELECTION TO REDEEM; NOTICE TO TRUSTEE. The election of the Company to redeem any Securities of any series pursuant to Section 1101 shall be evidenced by a Board Resolution. In case of any redemption at the election of the Company of less than all the Securities of any series, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers' Certificate evidencing compliance with such restriction. SECTION 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED. If less than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 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 and which may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of such series of a denomination larger than the minimum authorized denomination for Securities of that series. If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of 65 such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. In any case where more than one Security is registered in the same name, the Trustee in its discretion may treat the aggregate principal amount so registered as if it were represented by one Security. The Trustee shall promptly notify the Company 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 amount of such Securities which has been or is to be redeemed. SECTION 1104. NOTICE OF REDEMPTION. Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register. All notices of redemption shall state: (1) the Redemption Date, (2) the Redemption Price, (3) if less than all the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Securities of such series to be redeemed, (4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, (5) the place or places where such Securities are to be surrendered for payment of the Redemption Price, (6) that the redemption is pursuant to a sinking fund requirement, if such is the case, and 66 (7) if applicable, the conversion price, the date on which the right to convert the Securities to be redeemed will terminate and the place or places where such Securities may be surrendered for conversion. Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company's request, by the Trustee in the name and at the expense of the Company. SECTION 1105. DEPOSIT OF REDEMPTION PRICE. Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date in which event, interest shall be separately payable) accrued interest on, all the Securities which are to be redeemed on that date. SECTION 1106. SECURITIES PAYABLE ON REDEMPTION DATE. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; PROVIDED, HOWEVER, that instalments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. SECTION 1107. SECURITIES REDEEMED IN PART. Any Security which is to be redeemed only in part shall be surrendered at the office or agency of the Company maintained pursuant to Section 1002 for such purpose as a Place of Payment for Securities of that series (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 Security or Securities of the same series and of like tenor 67 and 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 Global Security is so surrendered, such new Security so issued shall be a new Global Security. ARTICLE TWELVE SINKING FUNDS SECTION 1201. APPLICABILITY OF ARTICLE. The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series except as otherwise specified as contemplated by Section 301 for Securities of such series. The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a "mandatory sinking fund payment", and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an "optional sinking fund payment". If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series. SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES. The Company (1) may deliver Outstanding Securities of a series (other than any previously called for redemption) and (2) may apply as a credit Securities of a series which have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of such series required to be made pursuant to the terms of such Securities as provided for by the terms of such Securities, provided that, such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 68 SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND. Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an Officers' Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 1202 and will also deliver to the Trustee any Securities to be so delivered. Not less than 45 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. The Company shall deposit the amount of cash, if any, required for such sinking fund payment with the Trustee in the manner provided in Section 1105. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107. ARTICLE THIRTEEN SUBORDINATION OF SECURITIES SECTION 1301. SECURITIES SUBORDINATE TO SENIOR INDEBTEDNESS. Except as otherwise provided in a supplemental indenture or pursuant to Section 301 the Company covenants and agrees, and each Holder of a Security, by his acceptance thereof, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article, the indebtedness represented by the Securities and the payment of the principal of (and premium, if any) and interest on each and all of the Securities are hereby expressly made subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness. SECTION 1302. PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC. In the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the Company or to its creditors, as such, or to its assets, or (b) any liquidation, dissolution or other winding up of the Company, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or any other marshalling of assets and liabilities of the Company, then and in any such event the holders of Senior Indebtedness shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Indebtedness, or provision shall be made for such payment in money or money's worth, before the Holders of the Securities are entitled to receive any payment on account of principal of (or premium, if any) or interest on the Securities, and 69 to that end the holders of Senior Indebtedness shall be entitled to receive, for application to the payment thereof, any payment or distribution of any kind or character, whether in cash, property or securities, which may be payable or deliverable in respect of the Securities in any such case, proceeding, dissolution, liquidation or other winding up or event. In the event that, notwithstanding the foregoing provisions of this Section, the Trustee or the Holder of any Security shall have received any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, before all Senior Indebtedness is paid in full or payment thereof provided for, and if such fact shall, at or prior to the time of such payment or distribution, have been made known to the Trustee or, as the case may be, such Holder, then and in such event such payment or distribution shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other Person making payment or distribution of assets of the Company for application to the payment of all Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior Indebtedness in full, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness. For purposes of this Article only, the words "cash, property or securities" shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment which are subordinated in right of payment to all Senior Indebtedness which may at the time be outstanding to substantially the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article. The consolidation of the Company with, or the merger of the Company into, another Person or the liquidation or dissolution of the Company following the conveyance or transfer of its properties and assets substantially as an entirety to another Person upon the terms and conditions set forth in Article Eight shall not be deemed a dissolution, winding up, liquidation, reorganization, assignment for the benefit of creditors or marshalling of assets and liabilities of the Company for the purposes of this Section if the Person formed by such consolidation or into which the Company is merged or which acquires by conveyance or transfer such properties and assets substantially as an entirety, as the case may be, shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions set forth in Article Eight. SECTION 1303. PRIOR PAYMENT TO SENIOR INDEBTEDNESS UPON ACCELERATION OF SECURITIES. In the event that any Securities are declared due and payable before their Stated Maturity, then and in such event the holders of the Senior Indebtedness outstanding at the time such Securities so become due and payable shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Indebtedness, or provision shall be made for such payment in money or money's worth before the Holders of the Securities are entitled to receive any payment by the Company on account of the principal of (or premium, if any) or interest on the Securities or on account of the purchase or other acquisition of Securities; PROVIDED, HOWEVER, that nothing in this Section shall prevent the satisfaction of any sinking fund 70 payment in accordance with Article Twelve by delivering and crediting pursuant to Section 1202 Securities which have been acquired (upon redemption or otherwise) prior to such declaration of acceleration or which have been converted pursuant to Article Fourteen. In the event that, notwithstanding the foregoing, the Company shall make any payment to the Trustee or the Holder of any Security prohibited by the foregoing provisions of this Section, and if such fact shall, at or prior to the time of such payment, have been made known to the Trustee or, as the case may be, such Holder, then and in such event such payment shall be paid over and delivered forthwith to the Company. The provisions of this Section shall not apply to any payment with respect to which Section 1302 would be applicable. SECTION 1304. NO PAYMENT WHEN SENIOR INDEBTEDNESS IN DEFAULT. (a) In the event and during the continuation of any default in the payment of principal of (or premium, if any) or interest on any Senior Indebtedness during or beyond any applicable grace period with respect thereto, or in the event that any default with respect to any Senior Indebtedness shall have occurred and be continuing permitting the holders of such Senior Indebtedness (or a trustee on behalf of the holders thereof) to declare such Senior Indebtedness due and payable prior to the date on which it would otherwise have become due and payable, unless and until such default shall have been cured or waived or shall have ceased to exist and, if any such Senior Indebtedness shall have been accelerated, such acceleration shall have been rescinded or annulled, or (b) in the event any judicial proceeding shall be pending with respect to any such default, then no payment shall be made by the Company on account of principal of (or premium, if any) or interest on the Securities or on account of the purchase or other acquisition of Securities; PROVIDED, HOWEVER, that nothing in this Section shall prevent the satisfaction of any sinking fund payment in accordance with Article Twelve by delivering and crediting pursuant to Section 1202 Securities which have been acquired (upon redemption or otherwise) prior to such declaration of acceleration or which have been converted pursuant to Article Fourteen. In the event that, notwithstanding the foregoing, the Company shall make any payment to the Trustee or the Holder of any Security prohibited by the foregoing provisions of this Section, and if such fact shall, at or prior to the time of such payment, have been made known to the Trustee or, as the case may be, such Holder, then and in such event such payment shall be paid over and delivered forthwith to the Company. The provisions of this Section shall not apply to any payment with respect to which Section 1302 would be applicable. 71 SECTION 1305. PAYMENT PERMITTED IF NO DEFAULT. Nothing contained in this Article or elsewhere in this Indenture or in any of the Securities shall prevent (a) the Company, at any time except during the pendency of any case, proceeding, dissolution, liquidation or other winding up, assignment for the benefit of creditors or other marshalling of assets and liabilities of the Company referred to in Section 1302 or under the conditions described in Section 1303 or 1304, from making payments at any time of principal of (and premium, if any) or interest on the Securities, or (b) the application by the Trustee of any money deposited with it hereunder to the payment of or on account of the principal of (and premium, if any) or interest on the Securities or the retention of such payment by the Holders, if, at the time of such application by the Trustee, it did not have knowledge that such payment would have been prohibited by the provisions of this Article. SECTION 1306. SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS. Subject to the payment in full of all Senior Indebtedness, the Holders of the Securities shall be subrogated to the rights of the holders of such Senior Indebtedness to receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness until the principal of (and premium, if any) and interest on the Securities shall be paid in full. For purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the Holders of the Securities or the Trustee would be entitled except for the provisions of this Article, and no payments over pursuant to the provisions of this Article to the holders of Senior Indebtedness by Holders of the Securities or the Trustee, shall, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Securities, be deemed to be a payment or distribution by the Company to or on account of the Senior Indebtedness. SECTION 1307. PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS. The provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities on the one hand and the holders of Senior Indebtedness on the other hand. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall (a) impair, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional (and which, subject to the rights under this Article of the holders of Senior Indebtedness, is intended to rank equally with all other general obligations of the Company), to pay to the Holders of the Securities the principal of (and premium, if any) and interest on the Securities as and when the same shall become due and payable in accordance with their terms; or (b) affect the relative rights against the Company of the Holders of the Securities and creditors of the Company other than the holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the 72 rights, if any, under this Article of the holders of Senior Indebtedness to receive cash, property and securities otherwise payable or deliverable to the Trustee or such Holder. SECTION 1308. TRUSTEE TO EFFECTUATE SUBORDINATION. Each Holder of a Security by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee his attorney-in-fact for any and all such purposes. SECTION 1309. NO WAIVER OF SUBORDINATION PROVISIONS. No right of any present or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any non-compliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Securities, without incurring responsibility to the Holders of the Securities and without impairing or releasing the subordination provided in this Article or the obligations hereunder of the Holders of the Securities to the holders of Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Indebtedness, or otherwise amend or supplement in any manner Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise dispose of any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any Person liable in any manner for the collection of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights against the Company and any other Person. SECTION 1310. NOTICE TO TRUSTEE. The Company shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit the making of any payment to or by the Trustee in respect of the Securities. Notwithstanding the provisions of this Article or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect of the Securities, unless and until the Trustee shall have received written notice thereof from the Company or a holder of Senior Indebtedness or from any trustee therefor; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Section 601, shall be entitled in all 73 respects to assume that no such facts exist; PROVIDED, HOWEVER, that if the Trustee shall not have received the notice provided for in this Section at least two Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without limitation, the payment of the principal of (and premium, if any) or interest on any Security), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it within two Business Days prior to such date. Subject to the provisions of Section 601, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness (or a trustee therefor) to establish that such notice has been given by a holder of Senior Indebtedness (or a trustee therefor). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article, and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. SECTION 1311. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING AGENT. Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee, subject to the provisions of Section 601, and the Holders of the Securities shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article. SECTION 1312. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS. The Trustee, in its capacity as trustee under this Indenture, shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company or to any other Person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article or otherwise. 74 SECTION 1313. RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS; PRESERVATION OF TRUSTEE'S RIGHTS. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. Nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 607. SECTION 1314. ARTICLE APPLICABLE TO PAYING AGENTS. In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term "Trustee" as used in this Article shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee; PROVIDED, HOWEVER, that Section 1313 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. SECTION 1315. CERTAIN CONVERSIONS DEEMED PAYMENT. For the purposes of this Article only, (1) the issuance and delivery of junior securities upon conversion of Securities in accordance with Article Fourteen shall not be deemed to constitute a payment or distribution on account of the principal of or premium or interest on Securities or on account of the purchase or other acquisition of Securities, and (2) the payment, issuance or delivery of cash, property or securities (other than junior securities) upon conversion of a Security shall be deemed to constitute payment on account of the principal of such Security. For the purposes of this Section, the term "junior securities" means (a) shares of any stock of any class of the Company and (b) securities of the Company which are subordinated in right of payment to all Senior Indebtedness which may be outstanding at the time of issuance or delivery of such securities to substantially the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Securities, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article Fourteen. 75 ARTICLE FOURTEEN CONVERSION OF SECURITIES SECTION 1401. APPLICABILITY OF ARTICLE. The provisions of this Article shall be applicable to the Securities of any series which are convertible into shares of Common Stock of the Company, and the issuance of such shares of Common Stock upon the conversion of such Securities, except as otherwise specified as contemplated by Section 301 for the Securities of such series. SECTION 1402. EXERCISE OF CONVERSION PRIVILEGE. In order to exercise a conversion privilege, the Holder of a Security of a series with such a privilege shall surrender such Security to the Company at the office or agency maintained for that purpose pursuant to Section 1002, accompanied by written notice to the Company that the Holder elects to convert such Security or a specified portion thereof. Such notice shall also state, if different from the name or names (with address) in which the Securities are registered, the name or names in which the certificate or certificates for shares of Common Stock which shall be issuable on such conversion shall be issued. Securities surrendered for conversion shall (if so required by the Company or the Trustee) be duly endorsed by or accompanied by instruments of transfer in forms satisfactory to the Company and the Trustee duly executed by the registered Holder or its attorney duly authorized in writing; and Securities so surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date (excluding Securities or portions thereof called for redemption during such period) shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of such Security then being converted, and such interest shall be payable to such registered Holder notwithstanding the conversion of such Security, subject to the provisions of Section 307 relating to the payment of Defaulted Interest by the Company. As promptly as practicable after the receipt of such notice and of any payment required pursuant to a Board Resolution and, subject to Section 303, set forth, or determined in the manner provided, in an Officers' Certificate, or established in one or more indentures supplemental hereto setting forth the terms of such series of Security, and the surrender of such Security in accordance with such reasonable regulations as the Company may prescribe, the Company shall issue and shall deliver, at the office or agency at which such Security is surrendered, to such Holder or on its written order, a certificate or certificates for the number of full shares of Common Stock issuable upon the conversion of such Security (or specified portion thereof), in accordance with the provisions of such Board Resolution, Officers' Certificate or supplemental indenture, and cash as provided therein in respect of any fractional share of such Common Stock otherwise issuable upon such conversion. Such conversion shall be deemed to have been effected immediately prior to the close of business on the date on which such notice and such payment, if required, shall have been received in proper order for conversion by the Company and such 76 Security shall have been surrendered as aforesaid (unless such Holder shall have so surrendered such Security and shall have instructed the Company to effect the conversion on a particular date following such surrender and such Holder shall be entitled to convert such Security on such date, in which case such conversion shall be deemed to be effected immediately prior to the close of business on such date) and at such time the rights of the Holder of such Security as such Security Holder shall cease and the person or persons in whose name or names any certificate or certificates for shares of Common Stock of the Company shall be issuable upon such conversion shall be deemed to have become the Holder or Holders of record of the shares represented thereby. Except as set forth above and subject to the final paragraph of Section 307, no payment or adjustment shall be made upon any conversion on account of any interest accrued on the Securities surrendered for conversion or on account of any dividends on the Common Stock of the Company issued upon such conversion. In the case of any Security which is converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to or on the order of the Holder thereof, at the expense of the Company, a new Security or Securities of the same series, of authorized denominations, in aggregate principal amount equal to the unconverted portion of such Security. SECTION 1403. NO FRACTIONAL SHARES. No fractional share of Common Stock of the Company shall be issued upon conversions of Securities of any series. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. If, except for the provisions of this Section 1403, any Holder of a Security or Securities would be entitled to a fractional share of Common Stock of the Company upon the conversion of such Security or Securities, or specified portions thereof, the Company shall pay to such Holder an amount in cash equal to the current market value of such fractional share computed, (i) if such Common Stock is listed or admitted to unlisted trading privileges on a national securities exchange, on the basis of the last reported sale price regular way on such exchange on the last Trading Day prior to the date of conversion upon which such a sale shall have been effected, or (ii) if such Common Stock is not at the time so listed or admitted to unlisted trading privileges on a national securities exchange, on the basis of the average of the bid and asked prices of such Common Stock in the over-the- counter market on the last Trading Day prior to the date of conversion, as reported by the National Quotation Bureau, Incorporated or similar organization if the National Quotation Bureau, Incorporated is no longer reporting such information, or if not so available, the fair market price as determined by the Board of Directors. 77 SECTION 1404. ADJUSTMENT OF CONVERSION PRICE. The conversion price of Securities of any series that is convertible into Common Stock of the Company shall be adjusted for any stock dividends, stock splits, reclassification, combinations or similar transactions in accordance with the terms of the supplemental indenture or Board Resolution setting forth the terms of the Securities of such series. Whenever the conversion price is adjusted, the Company shall compute the adjusted conversion price in accordance with terms of the applicable Board Resolution or supplemental indenture and shall prepare an Officers' Certificate setting forth the adjusted conversion price and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 1002 and, if different, with the Trustee. The Company shall forthwith cause a notice setting forth the adjusted conversion price to be mailed, first class postage prepaid, to each Holder of Securities of such series at its address appearing on the Security Register and to any conversion agent other than the Trustee. SECTION 1405. NOTICE OF CERTAIN CORPORATE ACTIONS. In case: (a) the Company shall declare a dividend (or any other distribution) on its Common Stock payable otherwise than in cash out of its retained earnings (other than a dividend for which approval of any shareholders of the Company is required); or (b) the Company shall authorize the granting to the holders of its Common Stock of rights, options or warrants to subscribe for or purchase any shares of capital stock of any class or of any other rights (other than any such grant for which approval of any shareholders of the Company is required); or (c) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding shares of Common Stock, or of any consolidation, merger or share exchange to which the Company is a party and for which approval of any shareholders of the Company is required), or of the sale of all or substantially all of the assets of the Company; or (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; then the Company shall cause to be filed with the Trustee, and shall cause to be mailed to all Holders at their last addresses as they shall appear in the Securities Register, at least 20 days (or 10 days in any case specified in clause (a) or (b) above) prior to the applicable record date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the 78 purpose of such dividend, distribution, rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights, options or warrants are to be determined, or (ii) the date on which such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up. If at any time the Trustee shall not be the conversion agent, a copy of such notice shall also forthwith be filed by the Company with the Trustee. SECTION 1406. RESERVATION OF SHARES OF COMMON STOCK. The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Securities, the full number of shares of Common Stock of the Company then issuable upon the conversion of all outstanding Securities of any series that has conversion rights. SECTION 1407. PAYMENT OF CERTAIN TAXES UPON CONVERSION. The Company will pay any and all taxes that may be payable in respect of the issue or delivery of shares of its Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of shares of its Common Stock in a name other than that of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless and until the person requesting such issue has paid to the Company the amount of any such tax, or has established, to the satisfaction of the Company, that such tax has been paid. SECTION 1408. NONASSESSABILITY. The Company covenants that all shares of its Common Stock which may be issued upon conversion of Securities will upon issue in accordance with the terms hereof be duly and validly issued and fully paid and nonassessable. SECTION 1409. EFFECT OF CONSOLIDATION OR MERGER ON CONVERSION PRIVILEGE. In case of any consolidation of the Company with, or merger of the Company into or with any other Person, or in case of any sale of all or substantially all of the assets of the Company, the Company or the Person formed by such consolidation or the Person into which the Company shall have been merged or the Person which shall have acquired such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then outstanding of any series that is convertible into Common Stock of the 79 Company shall have the right, which right shall be the exclusive conversion right thereafter available to said Holder (until the expiration of the conversion right of such Security), to convert such Security into the kind and amount of shares of stock or other securities or property (including cash) receivable upon such consolidation, merger or sale by a holder of the number of shares of Common Stock of the Company into which such Security might have been converted immediately prior to such consolidation, merger or sale, subject to compliance with the other provisions of this Indenture, such Security and such supplemental indenture. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in such Security. The above provisions of this Section shall similarly apply to successive consolidations, mergers or sales. It is expressly agreed and understood that anything in this Indenture to the contrary notwithstanding, if, pursuant to such merger, consolidation or sale, holders of outstanding shares of Common Stock of the Company do not receive shares of common stock of the surviving corporation but receive other securities, cash or other property or any combination thereof, Holders of Securities shall not have the right to thereafter convert their Securities into common stock of the surviving corporation or the corporation which shall have acquired such assets, but rather, shall have the right upon such conversion to receive the other securities, cash or other property receivable by a holder of the number of shares of Common Stock of the Company into which the Securities held by such holder might have been converted immediately prior to such consolidation, merger or sale, all as more fully provided in the first sentence of this Section 1409. Anything in this Section 1409 to the contrary notwithstanding, the provisions of this Section 1409 shall not apply to a merger or consolidation of another corporation with or into the Company pursuant to which both of the following conditions are applicable: (i) the Company is the surviving corporation and (ii) the outstanding shares of Common Stock of the Company are not changed or converted into any other securities or property (including cash) or changed in number or character or reclassified pursuant to the terms of such merger or consolidation. As evidence of the kind and amount of shares of stock or other securities or property (including cash) into which Securities may properly be convertible after any such consolidation, merger or sale, or as to the appropriate adjustments of the conversion prices applicable with respect thereto, the Trustee shall be furnished with and may accept the certificate or opinion of an independent certified public accountant with respect thereto; and, in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely thereon, and shall not be responsible or accountable to any Holder of Securities for any provision in conformity therewith or approved by such independent certified accountant which may be contained in said supplemental indenture. SECTION 1410. DUTIES OF TRUSTEE REGARDING CONVERSION. Neither the Trustee nor any conversion agent shall at any time be under any duty or responsibility to any Holder of Securities of any series that is convertible into Common Stock of the Company to determine whether any facts exist which may require any adjustment of the conversion price, or with respect to the nature or extent of any such adjustment when made, or 80 with respect to the method employed, whether herein or in any supplemental indenture, any resolutions of the Board of Directors or written instrument executed by one or more officers of the Company provided to be employed in making the same. Neither the Trustee nor any conversion agent shall be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock of the Company, or of any Securities and neither the Trustee nor any conversion agent makes any representation with respect thereto. Subject to the provisions of Section 601, neither the Trustee nor any conversion agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of its Common Stock or stock certificates or other securities or property upon the surrender of any Security for the purpose of conversion or to comply with any of the covenants of the Company contained in this Article Fourteen or in the applicable supplemental indenture, resolutions of the Board of Directors or written instrument executed by one or more duly authorized officers of the Company. SECTION 1411. REPAYMENT OF CERTAIN FUNDS UPON CONVERSION. Any funds which at any time shall have been deposited by the Company or on its behalf with the Trustee or any other paying agent for the purpose of paying the principal of, and premium, if any, and interest, if any, on any of the Securities (including funds deposited for the sinking fund referred to in Article Three hereof) and which shall not be required for such purposes because of the conversion of such Securities as provided in this Article Fourteen shall after such conversion be repaid to the Company by the Trustee upon the Company's written request. This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. In Witness Whereof, the parties hereto have caused this Indenture to be duly executed, and their respective corporate seals to be hereunto affixed and attested, all as of the day and year first above written.
