Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture (including certificates delivered pursuant to Section 10.09) shall include:

(a) a statement that each individual signing such certificate or opinion has read such condition or covenant and the definitions herein relating thereto;

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion as to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon an Opinion of Counsel, or a certificate or representations by counsel, unless such officer knows, or in the exercise of reasonable care should know, that the opinion, certificate or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such Opinion of Counsel or certificate or representations may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating that the information as to such factual matters is in the possession of the Company, unless such counsel knows that the certificate, opinion or representations as to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

Section 1.04. Acts of Holders . Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of the Outstanding Debentures of all series or one or more series, as the case may be, may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Debenture, shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section 1.04.

The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other reasonable manner which the Trustee deems sufficient.

The ownership of Registered Debentures shall be proved by the Debenture Register. As to any matter relating to beneficial ownership interests in any Global Debenture, the appropriate depositary's records shall be dispositive for purposes of this Indenture.

If the Company shall solicit from the Holders of Registered Debentures any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, in or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. Such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Debentures have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent,

waiver or other Act, and for that purpose the Outstanding Debentures shall be computed as of such record date; provided, however, that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later then eleven months after the record date.

Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Debenture shall bind every future Holder of the same Debenture and the Holder of every Debenture issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, any Debenture Registrar, any Paying Agent, any Authenticating Agent or the Company in reliance thereon, whether or not notation of such action is made upon such Debenture.

Section 1.05. Notices, Etc., To Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with:

(a) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at the address of its Corporate Trust Office specified in the first paragraph of this Indenture, Attention: Corporate Trust Department;

(b) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this Indenture or at any other address previously furnished in writing to the Trustee by the Company, Attention: Chief Financial Officer (with a copy to the Company's general counsel); or

(c) either the Trustee or the Company, by the other party shall be sufficient for every purpose hereunder if given by facsimile transmission, receipt confirmed by telephone followed by an original copy delivered by guaranteed overnight courier; if to the Trustee at facsimile number (612) 667-2160; and if to the Company at facsimile number (913) 451-3183.

Section 1.06. Notice to Holders; Waiver. Where this Indenture provides for notice of any event to Holders of Registered Debentures by the Company or the Trustee, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each such Holder affected by such event, at his address as it appears in the Debenture Register, not later than the latest date, and not earlier than the earliest date, if any, prescribed for the giving of such notice. In any case where notice to Holders of Registered Debentures is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders of Registered Debentures given as provided herein. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice.

If by reason of the suspension of or irregularities in regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification to Holders of Registered Debentures as shall be made with the approval of the Trustee shall constitute a sufficient notification to such Holders for every purpose hereunder.

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

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

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

Section 1.07. Counterparts; Effect of Headings and Table of Contents. This Indenture may be executed in any number of counterparts, each of which when executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same Indenture. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

Section 1.08. Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not.

Section 1.09. Severability Clause. In case any provision in this Indenture or in any Debenture shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 1.10. Benefits of Indenture. Nothing in this Indenture or in the Debentures, express or implied, shall give to any Person, other than the parties hereto, any Debenture Registrar, any Paying Agent, any Authenticating Agent and their successors hereunder and the Holders any benefit or any legal or equitable right, remedy or claim under this Indenture.

Section 1.11. Governing Law. This Indenture and the Debentures shall be governed by and construed in accordance with the law of the State of Kansas applicable to agreements made and to be performed therein.

Section 1.12. Legal Holidays. In any case where any Interest Payment Date, Redemption Date, Repayment Date, Stated Maturity or Maturity of any Debenture or the last date on which a Holder has the right to convert or exchange a Debenture shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or any Debenture other than a provision in the Debentures of any series which specifically states that such provision shall apply in lieu hereof), payment of interest or principal (and premium, if any) or conversion or exchange of such security need not be made at such Place of Payment on such date, but (except as otherwise provided in the supplemental indenture with respect to such Debenture) may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date, Redemption Date, Repayment Date or at the Stated Maturity or Maturity, or on such last day of conversion or exchange; provided, that no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date, Repayment Date, Stated Maturity or Maturity, as the case may be.

Section 1.13. Immunity of Stockholders, Directors, Officers and Agents of the Company. No recourse under or upon any obligation, covenant or agreement contained in this Indenture, or in any Debenture, or because of any indebtedness evidenced thereby, shall be had against any past, present or future stockholder, employee, officer or director, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Debentures by the Holders and as part of the consideration for the issue of the Debentures.

(r) the obligation, if any, of the Company to permit the conversion of the Debentures of such series into the Company's Common Stock or Preferred Stock, as the case may be, and the terms and conditions upon which such conversion shall be effected (including, without limitation, the initial conversion price or rate, the conversion period, any adjustment of the applicable conversion price and any requirements relative to the reservation of such shares for purposes of conversion) and applicable limitations on the ownership or transferability of the Common Stock or Preferred Stock into which such Debentures are convertible;

All Debentures of any one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the consent of the Holders, for issuances of additional Debentures of such series.

If any of the terms of the Debentures of any series are established by action taken pursuant to one or more Board Resolutions, a copy of an appropriate record of such action(s) shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or before the delivery of the Officers' Certificate setting forth the terms of the Debentures of such series.

Section 3.02. Denominations. The Debentures of each series shall be issuable in such denominations as shall be specified as contemplated by Section 3.01. With respect to Debentures of any series denominated in Dollars, in the absence of any such provisions with respect to the Debentures of any series, the Debentures of such series, other than Debentures issued in global form (which may be of any denomination), shall be issuable in denominations of $1,000 and any integral multiple thereof.

Section 3.03. Execution, Authentication, Delivery and Dating. The Debentures shall be executed on behalf of the Company by its Chairman of the Board, its President or one of its Executive or Senior Vice Presidents, and attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Debentures may be manual or facsimile signatures of the present or any future such authorized officer and may be imprinted or otherwise reproduced on the Debentures.

Debentures 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 before the authentication and delivery of such Debentures or did not hold such offices at the date of such Debentures.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Debentures of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Debentures, and the Trustee in accordance with the Company Order shall authenticate and deliver such Debentures.

If all the Debentures of any series are not to be issued at one time and if the Board Resolution or supplemental indenture establishing such series shall so permit, such Company Order may set forth procedures acceptable to the Trustee for the issuance of such Debentures and determining the terms of particular Debentures of such series, such as interest rate or formula, maturity date, date of issuance and date from which interest shall accrue. In authenticating such Debentures, and accepting the additional responsibilities under this Indenture in relation to such Debentures, the Trustee shall be entitled to receive, and shall be fully protected in relying upon:

(a) an Opinion of Counsel stating that:

(i) the form or forms of such Debentures have been established in conformity with the provisions of this Indenture;

(ii) the terms of such Debentures have been established in conformity with the provisions of this Indenture; and

(iii) such Debentures, when completed by appropriate insertions and executed and delivered by the Company to the Trustee for authentication in accordance with this Indenture, authenticated and delivered by the Trustee in accordance with this Indenture and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, fraudulent transfer, reorganization and other similar laws of general applicability relating to or affecting the enforcement of creditors' rights generally and to general equitable principles; and

(b) an Officers' Certificate stating that all conditions precedent provided for in this Indenture relating to the issuance of the Debentures have been complied with and that, to the best of the knowledge of the signers of such certificate, no Event of Default with respect to any of the Debentures shall have occurred and be continuing.

If such form or terms have been so established, the Trustee shall not be required to authenticate such Debentures if the issue of such Debentures pursuant to this Indenture will affect the Trustee's own rights, duties, obligations or immunities under the Debentures and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

Notwithstanding the provisions of Section 3.01 and of the preceding paragraph, if all the Debentures of any series are not to be issued at one time, it shall not be necessary to deliver an Officers' Certificate otherwise required pursuant to Section 3.01 or a Company Order, or an Opinion of Counsel or an Officers' Certificate otherwise required pursuant to the preceding paragraph at the time of issuance of each Debenture of such series, but such order, opinion and certificates, with appropriate modifications to cover such future issuances, shall be delivered at or before the time of closing of each such series or the closing of any portion thereof.

Each Registered Debenture shall be dated the date of its authentication.

No Debenture shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Debenture a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any Debenture shall be conclusive evidence, and the only evidence, that such Debenture has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Debenture (including a Global Debenture) shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Debenture to the Trustee for cancellation as provided in Section 3.09 together with a written statement (which need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel) stating that such Debenture has never been issued and sold by

the Company, for all purposes of this Indenture such Debenture shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

Section 3.04. Temporary Debentures. Pending the preparation of definitive Debentures of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Debentures which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Debentures in lieu of which they are issued, in registered form, and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Debentures may determine, as conclusively evidenced by their execution of such Debentures. In the case of Debentures of any series, such temporary Debentures may be in global form.

Except in the case of temporary Debentures (which shall be exchanged as otherwise provided herein or as otherwise provided in or pursuant to a Board Resolution), if temporary Debentures of any series are issued, the Company will cause definitive Debentures of that series to be prepared without unreasonable delay. After the preparation of definitive Debentures of such series, the temporary Debentures of such series shall be exchangeable for definitive Debentures of such series upon surrender of the temporary Debentures of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Debentures of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Debentures of the same series of authorized denominations. Until so exchanged, the temporary Debentures of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Debentures of such series.

Section 3.05. Registration, Registration of Transfer and Exchange. The Company shall cause to be kept at the Corporate Trust Office of the Trustee or in any office or agency of the Company in a Place of Payment a register for each series of Debentures (the registers maintained in such office or in any such office or agency of the Company in a Place of Payment being herein sometimes referred to collectively as the "Debenture Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Debentures and of transfers of Debentures. The Debenture Register shall be in written form or any other form capable of being converted into written form within a reasonable time. The Trustee, at its Corporate Trust Office, is hereby initially appointed "Debenture Registrar" for the purpose of registering Debentures and transfers of Debentures on such Debenture Register as herein provided. If the Trustee shall cease to be Debenture Registrar, it shall have the right to examine the Debenture Register at all reasonable times.

Subject to the provisions of this Section 3.05, upon surrender for registration of transfer of any Registered Debenture of any series at any office or agency of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Debentures of the same series, of any authorized denominations and of a like aggregate principal amount, bearing a number not contemporaneously outstanding, and containing identical terms and provisions.

Subject to the provisions of this Section 3.05, at the option of the Holder, Debentures of any series may be exchanged for other Debentures of the same series, of any authorized denomination or denominations and of a like aggregate principal amount, containing identical terms and provisions, upon surrender of the Debentures to be exchanged at any such office or agency. Whenever any such Debentures are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Debentures which the Holder making the exchange is entitled to receive.

Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 3.01, any permanent Global Debenture shall be exchangeable only as provided in this paragraph. If the depositary for any permanent Global Debenture is DTC, then, unless the terms of such Global

Debenture expressly permit such Global Debenture to be exchanged in whole or in part for definitive Debentures, a Global Debenture may be transferred, in whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC for such Global Debenture selected or approved by the Company or to a nominee of such successor to DTC. If at any time DTC notifies the Company that it is unwilling or unable to continue as depositary for the applicable Global Debenture or Debentures or if at any time DTC ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, if so required by applicable law or regulation, the Company shall appoint a successor depositary with respect to such Global Debenture or Debentures. If (a) a successor depositary for such Global Debenture or Debentures is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such unwillingness, inability or ineligibility, (b) an Event of Default has occurred and is continuing and the beneficial owners representing a majority in principal amount of the applicable series of Debentures represented by such Global Debenture or Debentures advise DTC to cease acting as depositary for such Global Debenture or Debentures or (c) the Company, in its sole discretion, determines at any time that all Outstanding Debentures (but not less than all) of any series issued or issuable in the form of one or more Global Debentures shall no longer be represented by such Global Debenture or Debentures, then the Company shall execute, and the Trustee shall authenticate and deliver, definitive Debentures of like series, rank, tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such Global Debenture or Debentures. If any beneficial owner of an interest in a permanent Global Debenture is otherwise entitled to exchange such interest for Debentures of such series and of like tenor and principal amount of another authorized form and denomination, as specified as contemplated by Section 3.01 and provided that any applicable notice provided in the permanent Global Debenture shall have been given, then without unnecessary delay but in any event not later than the earliest date on which such interest may be so exchanged, the Company shall execute, and the Trustee shall authenticate and deliver, definitive Debentures in aggregate principal amount equal to the principal amount of such beneficial owner's interest in such permanent Global Debenture. On or after the earliest date on which such interests may be so exchanged, such permanent Global Debenture shall be surrendered for exchange by DTC or such other depositary as shall be specified in the Company Order with respect thereto to the Trustee, as the Company's agent for such purpose; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Debentures to be redeemed and ending on the relevant Redemption Date if the Debenture for which exchange is requested may be among those selected for redemption. If a Registered Debenture is issued in exchange for any portion of a permanent Global Debenture after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date or (ii) any Special Record Date and the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Debenture, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such permanent Global Debenture is payable in accordance with the provisions of this Indenture.

All Debentures issued upon any registration of transfer or exchange of Debentures shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Debentures surrendered upon such registration of transfer or exchange.

Every Registered Debenture presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the Company or the Debenture Registrar) be duly endorsed, or be accompanied by a written instrument of transfer (including evidence of title and identity) in form satisfactory to the Company, the Trustee, the Company's designated agent (if any) and the Debenture 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 Debentures, 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 Debentures, other than exchanges pursuant to Section 3.04, 9.06, 11.07 or 13.05 not involving any transfer.

The Company or the Trustee, as applicable, shall not be required to (a) issue, register the transfer of or exchange any Debenture if such Debenture may be among those selected for redemption during a period beginning at the opening of business 15 days before date of mailing of the relevant notice of redemption and ending at the close of business on the date of the mailing of the relevant notice of redemption, or (b) register the transfer of or exchange any Registered Debenture so selected for redemption in whole or in part, except, in the case of any Registered Debenture to be redeemed in part, the portion thereof not to be redeemed, or (c) issue, register the transfer of or exchange any Debenture which has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Debenture not to be so repaid.

Section 3.06. Mutilated, Destroyed, Lost and Stolen Debentures. If any mutilated Debenture is surrendered to the Trustee or the Company, together with, in proper cases, such security or indemnity as may be required by the Company or the Trustee to save each of them or any agent of either of them harmless, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Debenture of the same series and principal amount, containing identical terms and provisions and bearing a number not contemporaneously outstanding appertaining to the surrendered Debenture.

If there shall be delivered to the Company and to the Trustee (a) evidence to their satisfaction of the destruction, loss or theft of any Debenture and (b) 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 Debenture has been acquired by a bona fide purchaser, the Company shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Debenture a new Debenture of the same series and principal amount, containing identical terms and provisions and bearing a number not contemporaneously outstanding appertaining to such destroyed, lost or stolen Debenture.

Notwithstanding the provisions of the previous two paragraphs, in case any such mutilated, destroyed, lost or stolen Debenture has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Debenture appertaining to such destroyed, lost or stolen Debenture, pay such Debenture.

Upon the issuance of any new Debenture under this Section 3.06, 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 Debenture of any series issued pursuant to this Section 3.06 in lieu of any destroyed, lost or stolen Debenture, shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Debenture 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 Debentures of that series duly issued hereunder.

The provisions of this Section 3.06 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 Debentures.

Section 3.07. Payment of Interest; Interest Rights Reserved. Except as otherwise specified with respect to a series of Debentures in accordance with the provisions of Section 3.01, interest on any Registered Debenture that 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 Debenture (or one or more Predecessor Debentures) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose pursuant to Section 10.02; provided, however, that each installment of interest on any Registered Debenture may at the Company's option be paid by (a) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 3.08, to the address of such Person as it appears on the Debenture Register or (b) wire transfer to an account maintained by the payee located inside the United States.

Unless otherwise provided as contemplated by Section 3.01, every permanent Global Debenture will provide that interest, if any, payable on any Interest Payment Date will be paid to DTC with respect to that portion of such permanent Global Debenture held for its account by Cede & Co for the purpose of permitting such party to credit the interest received by it in respect of such permanent Global Debenture to the accounts of the beneficial owners thereof.

Except as otherwise specified with respect to a series of Debentures in accordance with the provisions of Section 3.01, any interest on any Registered Debenture of any series that 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 registered Holder thereof on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election, in each case as provided in clause (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Debentures of such series (or their respective Predecessor Debentures) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Registered Debenture of such series and the date of the proposed payment (which shall not be less than 20 days after such notice is received by the Trustee), and at the same time the Company shall deposit with the Trustee an amount of money in the currency or currencies, currency unit or units or composite currency or currencies in which the Debentures of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Debentures of such series) equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when 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 Debentures of such series at his address as it appears in the Debenture Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an Authorized Newspaper in each Place of Payment, but such publications shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names the Debentures of such series (or their respective Predecessor Debentures) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b).

(b) The Company may make payment of any Defaulted Interest on the Debentures of any series in any other lawful manner not inconsistent with the requirements of any Debentures

exchange on which such Debentures may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee or 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 3.07 and Section 3.05, each Debenture delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Debenture shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Debenture.

Section 3.08. Persons Deemed Owners. Prior to due presentment of a Registered Debenture for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Registered Debenture is registered as the owner of such Debenture for the purpose of receiving payment of principal of (and premium, if any), and (subject to Sections 3.05 and 3.07) interest on, such Registered Debenture and for all other purposes whatsoever, whether or not such Registered Debenture 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. All such payments so made to any such Person, or upon such Person's order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for money payable upon any such Debenture.

No Holder of any beneficial interest in any Global Debenture held on its behalf by a depositary shall have any rights under this Indenture with respect to such Global Debenture and such depositary shall be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such Global Debenture for all purposes whatsoever. None of the Company, the Trustee, any Paying Agent or the Debenture Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Debenture or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Notwithstanding the foregoing, with respect to any Global Debenture, nothing herein shall prevent the Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by any depositary, as a Holder, with respect to such Global Debenture or impair, as between such depositary and owners of beneficial interests in such Global Debenture, the operation of customary practices governing the exercise of the rights of such depositary (or its nominee) as Holder of such Global Debenture.

Section 3.09. Cancellation. All Debentures surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Debentures and Debentures surrendered directly to the Trustee for any such purpose shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Debentures 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 Debentures previously authenticated hereunder which the Company has not issued and sold, and all Debentures so delivered shall be promptly cancelled by the Trustee. If the Company shall so acquire any of the Debentures, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Debentures unless and until the same are surrendered to the Trustee for cancellation. No Debentures shall be authenticated in lieu of or in exchange for any Debentures cancelled as provided in this Section 3.09, except as expressly permitted by this Indenture. Cancelled Debentures held by the Trustee shall be destroyed by the Trustee and the Trustee shall deliver a certificate of such destruction to the Company, unless the Trustee is otherwise directed by a Company Order.

Section 3.10. Computation of Interest. Except as otherwise specified as contemplated by Section 3.01 with respect to Debentures of any series, interest on the Debentures of each series shall be computed on the basis of a 360-day year consisting of twelve 30-day months.

ARTICLE IV

SATISFACTION AND DISCHARGE

Section 4.01. Satisfaction and Discharge of Indenture. This Indenture shall upon Company Request cease to be of further effect with respect to any series of Debentures specified in such Company Request (except as to any surviving rights of registration of transfer or exchange of Debentures of such series herein expressly provided for, and the Trustee, upon receipt of a Company Order, and at the expense of the Company, shall execute instruments in form and substance satisfactory to the Trustee and the Company acknowledging satisfaction and discharge of this Indenture as to such series when

(a) either:

(A) have become due and payable;

(B) will become due and payable at their Stated Maturity within one year; or

(C) if redeemable at the option of the Company, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company;

and the Company, in the case of (A), (B) or (C) above, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose an amount in the currency or currencies, currency unit or units or composite currency or currencies in which the Debentures of such series are payable, sufficient to pay and discharge the entire indebtedness on such Debentures not theretofore delivered to the Trustee for cancellation, for principal (and premium, if any) and interest, to the date of such deposit (in the case of Debentures which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be;

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such series have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee and any predecessor Trustee under Section 6.06, the obligations of the Company to any Authenticating Agent under Section 6.11 and, if money shall have been deposited with and held by the Trustee pursuant to clause (ii) of this Section 4.01, the obligations of the Trustee under Section 4.02 and the last paragraph of Section 10.03 shall survive.

Section 4.02. Application of Trust Funds. Subject to the provisions of the last paragraph of Section 10.03, all money deposited with the Trustee pursuant to Section 4.01 shall be held in trust and applied by it, in accordance with the provisions of the Debentures and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto of the principal (and premium, if any) and

any interest for whose payment such money has been deposited with or received by the Trustee, but such money need not be segregated from other funds except to the extent required by law.

ARTICLE V

REMEDIES

Section 5.01. Events of Default. "Event of Default," wherever used herein with respect to any particular series of Debentures and except as otherwise specified with respect to a series pursuant to Section 3.01, means any one of the following events (whatever the reason for such Event of Default and whether or not it shall 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):

(a) default in the payment of any interest upon any Debenture of that series when such interest becomes due and payable, and the continuance of such default for a period of days;

(d) default in the performance, or breach, of any covenant or warranty of the Company set forth in this Indenture with respect to any Debenture of that series (other than a covenant or warranty a default in the performance of which or the breach of which is elsewhere in this Section 5.01 specifically dealt with), and continuance of such default or breach for a period of 60 days after there has 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 % in principal amount of the Outstanding Debentures 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

(e) the Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(iii) orders the liquidation of the Company or any Significant Subsidiary and the order or decree remains unstayed and in effect for 90 days; or

(g) any other Event of Default provided with respect to Debentures of that series.

As used in this Section 5.01, the term "Bankruptcy Law" means Title 11, U.S. Code or any similar federal or state law for the relief of debtors and the term "Custodian" means any receiver, trustee, assignee, liquidator or other similar official under any Bankruptcy Law.

Section 5.02. Acceleration of Maturity; Rescission and Annulment. If an Event of Default with respect to Debentures of any series at the time Outstanding occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Debentures of that series may declare the principal amount (or, if Debentures of that series are Original Issue Discount Debentures or Indexed Debentures, such portion of the principal as may be specified in the terms thereof) of all the Debentures of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such principal or specified portion thereof shall become immediately due and payable.

At any time after such a declaration of acceleration with respect to Debentures 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 V provided, the Holders of a majority in principal amount of the Outstanding Debentures of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration of acceleration and its consequences if:

(a) the Company has paid or deposited with the Trustee a sum sufficient to pay in the currency in which the Debentures of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Debentures of such series):

(i) all overdue installments of interest on and payable in respect of all Outstanding Debentures of that series;

(ii) the principal of (and premium, if any, on) any Outstanding Debentures of that series which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates borne by or provided for in such Debentures;

(iii) to the extent that payment of such interest is lawful, interest upon overdue installments of interest at the rate or rates borne by or provided for in such Debentures; and

(iv) 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

(b) all Events of Default with respect to Debentures of that series, other than the nonpayment of the principal of (or premium, if any) or interest on Debentures of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13.

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

Section 5.03. Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if:

(a) default is made in the payment of any installment of interest on any Debenture of any series when such interest becomes due and payable and such default continues for a period of 30 days; or

(b) default is made in the payment of the principal of (or premium, if any, on) any Debenture of any series at its Maturity,

then the Company will, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Debentures of such series, the whole amount then due and payable on such Debentures for principal (and premium, if any) and interest, with interest upon any overdue principal (and premium, if

any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installments of interest at the rate or rates borne by or provided for in such Debentures, 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 and its agents and counsel.

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 Debentures of such series 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 Debentures of such series, wherever situated.

If an Event of Default with respect to Debentures 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 Debentures 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 5.04. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Debentures or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Debentures of any series shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Debentures of such series, of principal (and premium, if any) and interest owing and unpaid in respect of the Debentures and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel) and of the Holders allowed in such judicial proceeding; and

(b) to collect and receive any money or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or other similar official) in any such judicial proceeding is hereby authorized by each Holder of Debentures of such series to make such payments to the Trustee, and if the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee and any predecessor Trustee, their agents and counsel, and any other amounts due the Trustee or any predecessor Trustee under Section 6.06.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Debenture any plan of reorganization, arrangement, adjustment or composition affecting the Debentures or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Debenture in any such proceeding.

In any proceedings brought by the Trustee (and also any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party), the Trustee shall be held to

represent all the Holders of the Debentures, and it shall not be necessary to make any Holders of the Debentures parties to any such proceedings.

Section 5.05. Trustee May Enforce Claims Without Possession of Debentures. All rights of action and claims under this Indenture or any of the Debentures may be prosecuted and enforced by the Trustee without the possession of any of the Debentures 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 and its agents and counsel, be for the ratable benefit of the Holders of the Debentures in respect of which such judgment has been recovered.

Section 5.06. Application of Money Collected. Any money collected by the Trustee pursuant to this Article V 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, upon presentation of the Debentures, or both, as the case may be, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST, to the payment of all amounts due the Trustee and any predecessor Trustee under Section 6.06;

SECOND, to the payment of the amounts then due and unpaid upon the Debentures for the principal (and premium, if any) and interest payable, 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 aggregate amounts due and payable on such Debentures for principal (and premium, if any) and interest, respectively; and

THIRD, to the payment of the remainder, if any, to the Company.

Section 5.07. Limitation on Suits. No Holder of any Debenture 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:

(a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Debentures of that series;

(b) the Holders of not less than 25% in principal amount of the Outstanding Debentures 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;

(c) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request;

(d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(e) 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 Debentures 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, 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 such Holders.

Section 5.08. Unconditional Rights of Holders to Receive Principal, Premium, if any and Interest.
Notwithstanding any other provision in this Indenture, the Holder of any Debenture shall have the right, which is absolute and unconditional (subject to Sections 3.05 and 3.07), to receive payment of the principal of (and premium, if any) and interest on such Debenture on the respective due dates expressed in such Debenture (or, in the case of redemption, on the Redemption Date) 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 5.09. Restoration of Rights and Remedies. If the Trustee or any Holder of a Debenture 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, the Company, the Trustee and the Holders of Debentures shall, subject to any determination in such proceeding, 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.

Section 5.10. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debentures in the last paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Debentures 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 5.11. Delay or Omission not Waiver. No delay or omission of the Trustee or of any Holder of any Debenture 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 V 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 of Debentures, as the case may be.

Section 5.12. Control by Holders of Debentures. The Holders of not less than a majority in principal amount of the Outstanding Debentures 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 Debentures of such series, provided that:

(a) such direction shall not be in conflict with any rule of law or with this Indenture;

(b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; and

(c) the Trustee need not take any action which might involve it in personal liability or be unduly prejudicial to the Holders of Debentures of such series not joining therein.

Nothing in this Indenture shall impair the right of the Trustee in its discretion to take any action deemed proper by the Trustee and which is not inconsistent with such direction by Holders.

Section 5.13. Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Debentures of any series may on behalf of the Holders of all the Debentures of such series waive any past default hereunder with respect to such series and its consequences, except a default:

(a) in the payment of the principal of (or premium, if any) or interest on any Debenture of such series; or

(b) in respect of a covenant or provision hereof which under Article IX cannot be modified or amended without the consent of the Holder of each Outstanding Debenture of such series affected.

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon.

Section 5.14. Waiver of Usury, Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE VI

THE TRUSTEE

Section 6.01. Notice of Defaults. Within 90 days after the occurrence of any default hereunder with respect to the Debentures of any series, the Trustee shall transmit notice to each of the Holders of such series of such default hereunder known to the Trustee, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if any) or interest on such series, or in the payment of any sinking fund installment with respect to the Debentures of such series, the Trustee shall be protected in withholding such notice if and so long as a Responsible Officer of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders of the Debentures of such series; and provided further that in the case of any default or breach of the character specified in Section 5.01(d) with respect to the Debentures of such series, no such notice to Holders shall be given until at least 60 days after the occurrence thereof. For the purpose of this Section 6.01, the term "default" means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to the Debentures of such series.

Section 6.02. Certain Rights of Trustee.

(a) The Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties.

(b) Any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order (other than delivery of any Debenture to the Trustee for authentication and delivery pursuant to Section 3.03 which shall be sufficiently evidenced as provided therein) and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution.

(c) Whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the

Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers' Certificate.

(d) The Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

(e) The Trustee shall be under no obligation to exercise any of the rights or power vested in it by this Indenture at the request or direction of any of the Holders of Debentures of any series pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

(f) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon or other paper or document, unless requested in writing so to do by the Holders of not less than a majority in aggregate principal amount of the Outstanding Debentures of any series; provided that, if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such expenses or liabilities as a condition to proceeding; the reasonable expenses of every such examination shall be paid by the Holders or, if paid by the Trustee, shall be repaid by the Holders upon demand. The Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, relevant to the facts or matters that are the subject of its inquiry, personally or by agent or attorney.

(g) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder.

(h) The Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and reasonably believed by it to be authorized or within the discretion, rights or power conferred upon it by this Indenture.

The Trustee shall not be required to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

Except during the continuance of an Event of Default, the Trustee undertakes to perform only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee. If an Event of Default has occurred (which has not been cured), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

Section 6.03. Not Responsible for Recitals or Issuance of Debentures. The recitals contained herein and in the Debentures, except the Trustee's certificate of authentication, shall be taken as the statements of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Debentures, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Debentures and perform its obligations hereunder. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Debentures or the proceeds thereof.

Section 6.04. May Hold Debentures. The Trustee, any Paying Agent, Debenture Registrar, Authenticating Agent or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Debentures and may otherwise deal with the Company with the same rights it would have if it were not Trustee, Paying Agent, Debenture Registrar, Authenticating Agent or such other agent.

Section 6.05. Money Held in Trust. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company.

Section 6.06. Compensation and Reimbursement. The Company agrees:

(a) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(b) except as otherwise expressly provided herein, to reimburse each of the Trustee and any predecessor Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the reasonable expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and

(c) to indemnify each of the Trustee and any predecessor Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on its own part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder.

When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 5.01(e) or Section 5.01(f), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable federal or state bankruptcy, insolvency or other similar law.

As security for the performance of the obligations of the Company under this Section 6.06, the Trustee shall have a lien prior to the Debentures upon all property and money held or collected by the Trustee as such, except money held in trust for the payment of principal of (or premium, if any) or interest on particular Debentures.

The provisions of this Section 6.06 shall survive the termination of this Indenture.

Section 6.07. Corporate Trustee Required; Eligibility; Conflicting Interests. There shall at all times be a Trustee hereunder which shall have a combined capital and surplus of at least $25,000,000. If such entity publishes reports of condition at least annually, pursuant to law or the requirements of federal, state, territorial or District of Columbia supervising or examining authority, then for the

purposes of this Section 6.07, the combined capital and surplus of such entity 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 the Trustee shall cease to be eligible in accordance with the provisions of this Section 6.07, it shall resign immediately in the manner and with the effect hereinafter specified in this Article VI. Neither the Company nor any Person directly or indirectly controlling or controlled by, or under common control with, the Company shall serve as Trustee.

Section 6.08. Resignation and Removal; Appointment of Successor. No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article VI shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.09.

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

The Trustee may be removed at any time with respect to the Debentures of all series by Act of the Holders of a majority in principal amount of the Outstanding Debentures of all series delivered to the Trustee and to the Company.

If at any time:

(a) the Trustee shall cease to be eligible under Section 6.07 and shall fail to resign after written request therefor by the Company or by any Holder of a Debenture who has been a bona fide Holder of a Debenture for at least six months; or

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

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

If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause with respect to the Debentures, the Company, by or pursuant to a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Debentures. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Debentures shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Debentures of all series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee with respect to the Debentures and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Debentures shall have been so appointed by the Company or the Holders of Debentures and accepted appointment in the manner hereinafter provided, any Holder of a Debenture who has been a bona fide Holder of a Debenture for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Debentures.

The Company shall give notice of each resignation and each removal of the Trustee with respect to the Debentures and each appointment of a successor Trustee with respect to the Debentures in the manner provided for notices to the Holders of Debentures in Section 1.06. Each notice shall include the name of the successor Trustee with respect to the Debentures and the address of its Corporate Trust Office.

Section 6.09. Acceptance of Appointment by Successor. In case of the appointment hereunder of a successor Trustee with respect to all Debentures, every such successor Trustee 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 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, subject nevertheless to its claim, if any, provided for in Section 6.06.

In case of the appointment hereunder of a successor Trustee with respect to the Debentures, the Company, the retiring Trustee and each successor Trustee with respect to the Debentures shall execute and deliver an indenture supplemental hereto, pursuant to Article IX, wherein each successor Trustee shall accept such appointment and which (a) 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 Debentures and (b) 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 and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and the 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 Debentures.

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 this Section 6.09, as the case may be.

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 VI.

Section 6.10. Merger, Conversion, Consolidation or Succession to Business. Any entity into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder; provided such entity shall be otherwise qualified and eligible under this Article VI, without the execution or filing of any paper or any further act on the part of the parties hereto. In case any Debentures 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 Debentures so authenticated with the same effect as if such successor Trustee had itself authenticated such Debentures. In case any Debentures shall not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and deliver such Debentures, in either its own name or that of its predecessor Trustee, with the full force and effect which this Indenture provides for the certificate of authentication of the Trustee.

Section 6.11. Appointment of Authenticating Agent. The Trustee is hereby appointed the initial Authenticating Agent. At any time when any of the Debentures remain Outstanding, the Trustee may

appoint another Authenticating Agent or Agents with respect to one or more series of Debentures which shall be authorized to act on behalf of the Trustee to authenticate Debentures of such series issued upon exchange, registration of transfer or partial redemption or repayment thereof, and Debentures so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee, a copy of which instrument shall be promptly furnished to the Company. Wherever reference is made in this Indenture to the authentication and delivery of Debentures 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 bank or trust company or corporation organized and doing business and in good standing under the laws of the United States or of any state or the District of Columbia authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $25,000,000 and subject to supervision or examination by federal or state authorities. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 6.11, 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. In case at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 6.11, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section 6.11.

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 6.11, without the execution or filing of any paper or further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent for any series of Debentures may at any time resign by giving written notice of resignation to the Trustee for such series and to the Company. The Trustee for any series of Debentures may at any time terminate the agency of an Authenticating Agent by giving written notice of termination 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 6.11, the Trustee for such series may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment to all Holders of Debentures of the series with respect to which such Authenticating Agent will serve in the manner set forth in Section 1.06. 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 herein. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section 6.11.

The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation, including reimbursement of its reasonable expenses for its services under this Section 6.11.

Section 8.01. Consolidations and Mergers of Company and Sales, Leases and Conveyances Permitted Subject to Certain Conditions. The Company may consolidate with, or sell, lease or convey

all or substantially all of its assets to, or merge with or into any other entity, provided that in any such case (a) either the Company shall be the continuing entity, or the successor entity (if other than the Company) formed by or resulting from any such consolidation or merger or which shall have received the transfer of such assets shall be an entity organized and existing under the laws of the United States or a state thereof and such successor entity shall expressly assume the due and punctual payment of the principal of (and premium, if any) and any interest on all of the Debentures, according to their tenor, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed by the Company by supplemental indenture, complying with Article IX, satisfactory to the Trustee, executed and delivered to the Trustee by such entity and (b) immediately after giving effect to such transaction and treating any indebtedness which becomes an obligation of such successor entity, the Company or any Subsidiary as a result thereof as having been incurred by such successor entity, the Company or such Subsidiary at the time of such transaction, no Event of Default, and no event which, after notice or the lapse of time, or both, would become an Event of Default, shall have occurred and be continuing.

Such successor corporation thereupon may cause to be signed, and may issue either in its own name or in the name of the Company, any or all of the Debentures issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor corporation, instead of the Company, and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Debentures which previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Debentures which such successor corporation thereafter shall cause to be signed and delivered to the Trustee for that purpose.

(b) reduce the percentage in principal amount of the Outstanding Debentures of any series, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver with respect to such series (or compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture; or

Debentures of any series authenticated and delivered after the execution of any supplemental indenture pursuant to this Article IX may, and shall, if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new

The Company shall maintain in each Place of Payment for any series of Debentures an office or agency where Debentures of that series may be presented or surrendered for payment or conversion, where Debentures of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Debentures of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of each 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.

The Company may from time to time designate one or more other offices or agencies where the Debentures of one or more series may be presented or surrendered for any or all of 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 accordance with the requirements set forth above for Debentures of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. Unless otherwise specified with respect to any Debentures pursuant to Section 3.01 with respect to a series of Debentures, the Company hereby designates as a Place of Payment for each series of Debentures the office or agency of the

Trustee, in the City of Minneapolis, Minnesota, and initially appoints the Trustee at its Corporate Trust Office as Paying Agent in such city and as its agent to receive all such presentations, surrenders, notices and demands.

Section 10.03. Money for Debentures 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 any Debentures, it will, on or before each due date of the principal of (and premium, if any), or interest on the Debentures of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the currency or currencies, currency unit or units or composite currency or currencies in which the Debentures of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Debentures of such series) 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 Debentures, it will, on or before each due date of the principal of (and premium, if any), or interest on any Debentures of that series, deposit with a Paying Agent a sum (in the currency or currencies, currency unit or units or composite currency or currencies described in the preceding paragraph) sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held 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 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 10.03, that such Paying Agent will:

(a) hold all sums held by it for the payment of principal of (and premium, if any) or interest on Debentures 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;

(b) give the Trustee notice of any default by the Company (or any other obligor upon the Debentures) in the making of any such payment of principal (and premium, if any) or interest on the Debentures of that series; and

(c) at any time during the continuance of any such default upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same terms as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

Except as otherwise provided in the Debentures of any series, 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 Debenture of any series and remaining unclaimed for two years after such principal (and premium, if any), interest has become due and payable shall be paid to the Company upon Company Request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Debenture shall thereafter, as an unsecured general creditor, look only to the Company for payment of such principal of (and premium, if any) or interest on any Debenture, without interest thereon, 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 an Authorized Newspaper, 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 10.04. Existence. Subject to Article VIII, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, all material rights (by certificate of incorporation, bylaws and statute) and material franchises; provided, however, that the Company shall not be required to preserve any 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.

Section 10.05. Maintenance of Properties. The Company will cause all of its material properties used or useful in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that the Company and its Subsidiaries shall not be prevented from selling or otherwise disposing of their properties for value in the ordinary course of their business.

Section 10.06. Insurance. The Company will, and will cause each of its Subsidiaries to, keep in force upon all of its properties and operations policies of insurance carried with responsible companies in such amounts and covering all such risks as shall be customary in the industry in accordance with prevailing market conditions and availability.

Section 10.07. 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, (a) all taxes, assessments and governmental charges levied or imposed upon it or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary and (b) 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 the amount, applicability or validity of which is being contested in good faith by appropriate proceedings, provided all liabilities relating to such tax, assessment, charge or claim are adequately provided for on the books of the Company in accordance with GAAP. The Company, any Subsidiaries and any partnership in which the Company or its Subsidiaries are a partner shall timely and accurately file all tax returns required by law to have been filed.

Section 10.08. Provision of Financial Information. Whether or not the Company is subject to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended, the Company will, within 15 days after each of the respective dates by which the Company would have been required to file annual reports, quarterly reports and other documents with the Commission if the Company were so subject, (a) transmit by mail to all Holders, as their names and addresses appear in the Debenture Register, without cost to such Holders summaries of the annual reports, quarterly reports and other documents which the Company would have been required to file with the Commission pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended, if the Company were subject to such Sections, and (b) file with the Trustee copies of the annual reports, quarterly reports and other documents which the Company would have been required to file with the Commission pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended, if the Company were subject to such Sections and (c) promptly upon written request and payment of the reasonable cost of duplication and delivery, supply copies of such documents to any prospective Holder.

Section 10.09. Statement as to Compliance. The Company will deliver to the Trustee, within 120 days after the end of each Fiscal Year, a brief certificate from the principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of the Company's compliance with all conditions and covenants under this Indenture and, in the event of any noncompliance, specifying such noncompliance and the nature and status thereof. For purposes of this Section 10.09, such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

Section 10.10. Waiver of Certain Covenants. The Company may omit in any particular instance to comply with any term, provision or condition set forth in Sections 10.04 to 10.08, inclusive, if before or after the time for such compliance the Holders of at least a majority in principal amount of all outstanding Debentures of such series, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

Section 10.11. Subordination. The payment of the principal of (and premium, if any) and interest on the Debentures is, to the extent set forth in this Indenture, subordinated in right of payment to the prior payment in full of all Senior Indebtedness, whether currently outstanding or subsequently incurred. "Senior Indebtedness" is defined as:

(a) the principal of (and premium, if any) and interest on indebtedness of the Company for money borrowed from or guaranteed to banks, trust companies, insurance companies, or pension trusts or evidenced by securities issued under the provisions of an indenture or similar instrument between the Company and a bank or trust company other than indebtedness evidenced by instruments which expressly provide that such indebtedness is not superior in right of payment to the Subordinated Debentures issued under this Indenture; and

(b) indebtedness created after the date of this Indenture, as to which the instrument creating or evidencing the indebtedness provides that such indebtedness is superior in right of payment to the Debentures issued under this Indenture.

By reason of the subordination provisions of this Indenture, no payment on account of principal of (or premium, if any) or interest on the Debentures shall be made, and no Debentures shall be purchased, either directly or indirectly, by the Company or any of its Subsidiaries, unless full payment of amounts then due for principal of (and premium, if any) and interest (including interest on overdue principal and interest, to the extent permitted by law) on Senior Indebtedness has been made or duly provided for. In addition, no payment on account of principal of (or premium, if any) or interest on the Debentures shall be made, and no Debentures shall be purchased, either directly or indirectly, by the Company or any of its Subsidiaries, if at the time of such payment or purchase or immediately after giving effect to such payment or purchase, there shall exist under any Senior Indebtedness or any indenture or agreement pursuant to which any Senior Indebtedness is issued any default or any condition, event or act, which, with notice or lapse of time, or both, would constitute a default.

In the event that any Debenture is declared due and payable before its stated maturity or upon any other acceleration of payment of the principal of the Debentures because of an Event of Default and upon any payment or distribution of assets of the Company, whether in cash, property or securities, to creditors, all principal of (and premium, if any) and interest (including interest on overdue principal and interest) due or to become due upon all Senior Indebtedness shall first be paid in full before the Holders of the Debentures or the Trustee under this Indenture shall be entitled to retain any assets so paid or distributed in respect of the Debentures (for principal, premium, if any, or interest). Any such payment or distribution of assets of the Company, whether in cash, property or securities, to which the Holders of the Debentures or the Trustee would otherwise be entitled, shall be

paid by the Company directly to the owners of Senior Indebtedness (pro rata), or their representatives, to the extent necessary to pay all Senior Indebtedness in full, after giving effect to any concurrent payment or distribution to or for the owners of Senior Indebtedness, before any payment or distribution is made to the Holders of the Debentures or to the Trustee under this Indenture. By reason of such subordination, in the event of the Company's insolvency, holders of Senior Indebtedness may receive more, ratably, and the Holders of the Debentures may receive less, ratably, than other creditors of the Company.

ARTICLE XI

REDEMPTION OF DEBENTURES

Section 11.01. Applicability of Article. Debentures 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 3.01 for Debentures of any series) in accordance with this Article XI. The Series A and Series B Debentures are redeemable by the Company at its option on any Interest Payment Date.

Section 11.02. Election to Redeem; Notice to Trustee. The election of the Company to redeem any Debentures shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of the Company of less than all of the Debentures of any series, the Company shall, at least 45 days prior to the giving of the notice of redemption in Section 11.04 (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Debentures of such series to be redeemed. In the case of any redemption of Debentures prior to the expiration of any restriction on such redemption provided in the terms of such Debentures or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers' Certificate evidencing compliance with such restriction.

Section 11.03. Selection by Trustee of Debentures to be Redeemed. If less than all the Debentures of any series issued on the same day with the same terms are to be redeemed, the particular Debentures to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Debentures of such series issued on such date with the same terms 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 Debentures of that series or any integral multiple thereof) of the principal amount of Debentures of such series of a denomination larger than the minimum authorized denomination for Debentures of that series.

The Trustee shall promptly notify the Company and the Debenture Registrar (if other than itself) in writing of the Debentures selected for redemption and, in the case of any Debentures 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 Debentures shall relate, in the case of any Debenture redeemed or to be redeemed only in part, to the portion of the principal amount of such Debenture which has been or is to be redeemed.

Section 11.04. Notice of Redemption. Notice of redemption shall be given in the manner provided in Section 1.06, not less than 30 days nor more than 60 days prior to the Redemption Date, unless a shorter period is specified by the terms of such series established pursuant to Section 3.01, to each Holder of Debentures to be redeemed, but failure to give such notice in the manner herein provided to the Holder of any Debenture designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other such Debenture or portion thereof.

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

All notices of redemption shall state:

(a) the Redemption Date;

(b) the Redemption Price, accrued interest to the Redemption Date payable as provided in Section 11.06, if any;

(c) if less than all Outstanding Debentures of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amount) of the particular Debenture or Debentures to be redeemed;

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

(e) that on the Redemption Date the Redemption Price and accrued interest to the Redemption Date payable as provided in Section 11.06, if any, will become due and payable upon each such Debenture, or the portion thereof, to be redeemed and, if applicable, that interest thereon shall cease to accrue on and after said date;

(f) the Place or Places of Payment where such Debentures maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and accrued interest, if any, or for conversion;

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

(h) the CUSIP number of such Debenture, if any; and

(i) if applicable, that a Holder of Debentures who desires to convert Debentures for redemption must satisfy the requirements for conversion contained in such Debentures, the then-existing conversion price or rate, the place or places where such Debentures may be surrendered for conversion, and the date and time when the option to convert shall expire.

Notice of redemption of Debentures 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 11.05. Deposit of Redemption Price. Prior to 11:00 a.m. EST on 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, which it may not do in the case of a sinking fund payment under Article XII, segregate and hold in trust as provided in Section 10.03) an amount of money in the currency or currencies, currency unit or units or composite currency or currencies in which the Debentures of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Debentures of such series) sufficient to pay on the Redemption Date the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Debentures or portions thereof which are to be redeemed on that date.

If any Debenture called for redemption is converted, any money deposited with the Trustee or with any Paying Agent or so segregated and held in trust for the redemption of such Debenture shall be paid to the Company upon Company Request or, if then held by the Company, shall be discharged from such trust.

Section 11.06. Debentures Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Debentures 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). Upon surrender of any such Debenture for redemption in accordance with said notice, maturing after the Redemption Date, such Debenture shall be paid by the Company at the Redemption Price on the Redemption Date.

If any Debenture 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 borne by the Debenture.

Section 11.07. Debentures Redeemed in Part. Any Registered Debenture which is to be redeemed only in part (pursuant to the provisions of this Article XI or of Article XII) shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his or her attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Debenture without service charge a new Debenture or Debentures of the same series 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 Debenture so surrendered. If a Global Debenture is so surrendered, the Company shall execute and the Trustee shall authenticate and deliver to the depositary, without service charge, a new Global Debenture in a denomination equal to and in exchange for the unredeemed portion of the principal of the Global Debenture so surrendered.

ARTICLE XII

SINKING FUNDS

Section 12.01. Applicability of Article. The provisions of this Article XII shall be applicable to any sinking fund for the retirement of Debentures of a series except as otherwise specified as contemplated by Section 3.01 for Debentures of such series. The Class A and Class B Debentures shall not be subject to a sinking fund.

The minimum amount of any sinking fund payment provided for by the terms of Debentures 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 such Debentures of any series is herein referred to as an "optional sinking fund payment." If provided for by the terms of any Debentures of any series, the cash amount of any mandatory sinking fund payment may be subject to reduction as provided in Section 12.02. Each sinking fund payment shall be applied to the redemption of Debentures of any series as provided for by the terms of Debentures of such series.

Section 12.02. Satisfaction of Sinking Fund Payments with Debentures. The Company may, in satisfaction of all or any part of any mandatory sinking fund payment with respect to the Debentures of a series, (a) deliver Outstanding Debentures of such series (other than any previously called for redemption) and (b) apply as a credit Debentures of such series which have been redeemed either at the election of the Company pursuant to the terms of such Debentures or through the application of permitted optional sinking fund payments pursuant to the terms of such Debentures, as provided for by the terms of such Debentures, or which have otherwise been acquired by the Company; provided, however, that such Debentures so delivered or applied as a credit have not been previously so credited. Such Debentures shall be received and credited for such purpose by the Trustee at the applicable Redemption Price specified in such Debentures for redemption through operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly.

Section 12.03. Redemption of Debentures for Sinking Fund. Not less than 60 days prior to each sinking fund payment date for Debentures of any series, the Company will deliver to the Trustee an Officers' Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that

series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash in the currency in which the Debentures of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Debentures of such series) and the portion thereof, if any, which is to be satisfied by delivering and crediting Debentures of that series pursuant to Section 12.02, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Debentures to be so delivered and credited. If such Officers' Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein specified. Not less than 30 days before each such sinking fund payment date the Trustee shall select the Debentures to be redeemed upon such sinking fund payment date in the manner specified in Section 11.03 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 11.04. Such notice having been duly given, the redemption of such Debentures shall be made upon the terms and in the manner stated in Sections 11.06 and 11.07.

ARTICLE XIII

REPAYMENT AT THE OPTION OF HOLDERS

Section 13.01. Applicability of Article. Repayment of Debentures of any series before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms of such Debentures, if any, and (except as otherwise specified by the terms of such series established pursuant to Section 3.01) in accordance with this Article XIII.

Section 13.02. Repayment of Debentures. Debentures of any series subject to repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided in the terms of such Debentures, be repaid at a price equal to the principal amount thereof, together with interest, if any, thereon accrued to the Repayment Date specified in or pursuant to the terms of such Debentures. The Company covenants that on or prior to the Repayment Date it will 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 10.03) an amount of money in the currency or currencies, currency unit or units or composite currency or currencies in which the Debentures of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Debentures of such series) sufficient to pay the principal (or, if so provided by the terms of the Debentures of any series, a percentage of the principal) of, and (except if the Repayment Date shall be an Interest Payment Date) accrued interest on, all the Debentures or portions thereof, as the case may be, to be repaid on such date.

Section 13.03. Exercise of Option. Debentures of any series subject to repayment at the option of the Holders thereof will contain an "Option to Elect Repayment" form on the reverse of such Debentures. In order for any Debenture to be repaid at the option of the Holder, the Trustee must receive at the Place of Payment therefor specified in the terms of such Debenture (or at such other place or places of which the Company shall from time to time notify the Holders of such Debentures) not earlier than 60 days nor later than 30 days prior to the Repayment Date (a) the Debenture so providing for such repayment together with the "Option to Elect Repayment" form on the reverse thereof duly completed by the Holder (or by the Holder's attorney duly authorized in writing) or (b) a telegram, telex, facsimile transmission or letter from a member of a national securities exchange, or the National Association of Debentures Dealers, Inc., or a commercial bank or trust company in the United States setting forth the name of the Holder of the Debenture, the principal amount of the Debenture, the principal amount of the Debenture to be repaid, the CUSIP number, if any, or a description of the tenor and terms of the Debenture, a statement that the option to elect repayment is being exercised thereby and a guarantee that the Debenture to be repaid, together with the duly completed form entitled "Option to Elect Repayment" on the reverse of the Debenture, will be received by the Trustee not later than the fifth Business Day after the date of such telegram, telex,

facsimile transmission or letter; provided, however, that such telegram, telex, facsimile transmission or letter shall only be effective if such Debenture and form duly completed are received by the Trustee by such fifth Business Day. If less than the entire principal amount of such Debenture is to be repaid in accordance with the terms of such Debenture, the principal amount of such Debenture to be repaid, in increments of the minimum denomination for Debentures of such series, and the denomination or denominations of the Debenture or Debentures to be issued to the Holder for the portion of the principal amount of such Debenture surrendered that is not to be repaid, must be specified. The principal amount of any Debenture providing for repayment at the option of the Holder thereof may not be repaid in part if, following such repayment, the unpaid principal amount of such Debenture would be less than the minimum authorized denomination of Debentures of the series of which such Debenture to be repaid is a part. Except as otherwise may be provided by the terms of any Debenture providing for repayment at the option of the Holder thereof, exercise or the repayment option by the Holder shall be irrevocable unless waived by the Company.

Section 13.04. When Debentures Presented for Repayment Become Due and Payable. If Debentures of any series providing for repayment at the option of the Holders thereof shall have been surrendered as provided in this Article XIII and as provided by or pursuant to the terms of such Debentures, such Debentures or the portions thereof, as the case may be, to be repaid shall become due and payable and shall be paid by the Company on the Repayment Date therein specified, and on and after such Repayment Date (unless the Company shall default in the payment of such Debentures on such Repayment Date) such Debentures shall, if the same were interest-bearing, cease to bear interest so to be repaid, except to the extent provided below, shall be void. Upon surrender of any such Debenture for repayment in accordance with such provisions maturing after the Repayment Date, the principal amount of such Debenture so to be repaid shall be paid by the Company, together with accrued interest, if any, to the Repayment Date; provided, that, in the case of Debentures, installments of interest, if any, whose Stated Maturity is on or prior to the Repayment Date shall be payable (but without interest thereon, unless the Company shall default in the payment thereof) to the Holders of such Debentures, or one or more Predecessor Debentures, registered as such at the close of business on the relevant record dates according to their terms and the provisions of Section 3.07.

If the principal amount of any Debenture surrendered for repayment shall not be so repaid upon surrender thereof, such principal amount (together with interest, if any, thereon accrued to such Repayment Date) shall, until paid, bear interest from the Repayment Date at the rate of interest or Yield to Maturity (in the case of Original Issue Discount Debentures) set forth in such Debenture.

Section 13.05. Debentures Repaid in Part. Upon surrender of any Registered Debenture which is to be repaid in part only, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Debenture, without service charge and at the expense of the Company, a new Registered Debenture or Debentures of the same series, of any authorized denomination specified by the Holder, in an aggregate principal amount equal to and in exchange for the portion of the principal of such Debenture so surrendered which is not to be repaid.

ARTICLE XIV

DEFEASANCE AND COVENANT DEFEASANCE

Section 14.01. Applicability of Article; Company's Option to Effect Defeasance or Covenant Defeasance. If, pursuant to Section 3.01, provision is made for either or both of (a) defeasance of the Debentures of or within a series under Section 14.02 or (b) covenant defeasance of the Debentures of or within a series under Section 14.03, then the provisions of such Section or Sections, as the case may be, together with the other provisions of this Article XIV (with such modifications thereto as may be specified pursuant to Section 3.01 with respect to any Debentures), shall be applicable to such Debentures, and the Company may at its option by Board Resolution, at any time, with respect to such

Debentures, elect to have Section 14.02 (if applicable) or Section 14.03 (if applicable) be applied to such Outstanding Debentures upon compliance with the conditions set forth below in this Article XIV.

Section 14.02. Defeasance and Discharge. Upon the Company's exercise of the above option applicable to this Section 14.02 with respect to any Debentures of or within a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Debentures on the date the conditions set forth in Section 14.04 are satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Debentures, which shall thereafter be deemed to be "Outstanding" only for the purposes of Section 14.05 and the other Sections of this Indenture referred to in clauses (a) and (b) below, and to have satisfied all of its other obligations under such Debentures and this Indenture insofar as such Debentures are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of such Outstanding Debentures to receive, solely from the trust fund described in Section 14.04 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any) and interest, if any, on such Debentures when such payments are due, (b) the Company's obligations with respect to such Debentures under Sections 3.05, 3.06, 10.02 and 10.03, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (d) this Article XIV. Subject to compliance with this Article XIV the Company may exercise its option under this Section 14.02 notwithstanding the prior exercise of its option under Section 14.03 with respect to such Debentures.

Section 14.03. Covenant Defeasance. Upon the Company's exercise of the above option applicable to this Section with respect to any Debentures of or within a series, the Company shall be released from its obligations under Sections 10.04 to 10.08, inclusive, and, if specified pursuant to Section 3.01, its obligations under any other covenant, with respect to such Outstanding Debentures on and after the date the conditions set forth in Section 14.04 are satisfied (hereinafter, "covenant defeasance"), and such Debentures shall thereafter be deemed to be not "Outstanding" for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with Sections 10.04 to 10.08, inclusive, or such other covenant, but shall continue to be deemed "Outstanding" for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Debentures, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section or such other covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or by reason of reference in any such Section or such other covenant to any other provision herein or in any other document, and such omission to comply shall not constitute a default or an Event of Default under Section 5.01(d) or 5.01(h) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Debentures shall be unaffected thereby.

Section 14.04. Conditions to Defeasance or Covenant Defeasance. The following shall be the conditions to application of Section 14.02 or Section 14.03 to any Outstanding Debentures of or within a series:

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

(c) No Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect to such Debentures shall have occurred and be continuing on the date of such deposit or, insofar as Sections 5.01(f) and 5.01(g) are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(d) In the case of an election under Section 14.02, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since the date of execution of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Debentures will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred.

(e) In the case of an election under Section 14.03, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Outstanding Debentures will not recognize income, gain or loss for federal income tax purposes as a result of such covenant defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

(f) The Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance under Section 14.02 or the covenant defeasance under Section 14.03 (as the case may be) have been complied with and an Opinion of Counsel to the effect that either (i) as a result of a deposit pursuant to clause (a) above and the related exercise of the Company's option under Section 14.02 or 14.03 (as the case may be), registration is not required under the Investment Company Act of 1940, as amended, by the Company, with respect to the trust funds representing such deposit or by the Trustee for such trust funds or (ii) all necessary registrations under said act have been effected.

(g) Notwithstanding any other provisions of this Section 14.04, such defeasance or covenant defeasance shall be effected in compliance with any additional or substitute terms, conditions or limitations which may be imposed on the Company in connection therewith pursuant to Section 3.01.

Section 14.05. Deposited Money and Government Obligations to be Held in Trust; Other Miscellaneous Provisions. Subject to the provisions of the last paragraph of Section 10.03, all money and Government Obligations (or other property as may be provided pursuant to Section 3.01) (including the proceeds thereof) deposited with the Trustee (or other qualifying Trustee, collectively for purposes of this Section 14.05, the "Trustee") pursuant to Section 14.04 in respect of any Outstanding Debentures of any series shall be held in trust and applied by the Trustee, in accordance with the provisions of such Debentures and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Debentures of all sums due and to become due thereon in respect of principal (and premium, if any) and interest but such money need not be segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the Government Obligations deposited pursuant to Section 14.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Outstanding Debentures.

Anything in this Article XIV to the contrary notwithstanding, subject to Section 6.06, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in Section 14.04 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a defeasance or covenant defeasance, as applicable, in accordance with this Article XIV.
