In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. 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. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the -13- Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the initial issuance of Securities of such series. Notwithstanding the foregoing, if the Board Resolution, action pursuant to Board Resolution or indenture supplemental hereto establishing the terms of the Securities of any series shall specify that the automated issuance system described in Section 311 (or any other system, method or procedures for the determination of terms of Securities of any series that are to be issued from time to time) shall be available for the Securities of such series, any terms of the Securities of such series shall be established in the manner provided for pursuant to such system, method or procedures. SECTION 302. Denominations. ------------- The Securities of each series shall be issuable in registered form without coupons in such denominations as shall be specified as contemplated by Section 301.

Securities of each series shall be numbered, lettered or otherwise distinguished in such manner or in accordance with such plan as the officers of the Company executing the same may determine with the approval of the Trustee. SECTION 303. Execution, Authentication, Delivery and Dating. ---------------------------------------------- The Securities shall be executed on behalf of the Company by its Chairman of the Board, its President, one of its Vice Presidents or its Treasurer, and by its Secretary or one of its Assistant Secretaries or one of its Assistant Treasurers, under its corporate seal or a facsimile thereof reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of the Securities of such series, and the Trustee in accordance with the Company Order shall either at one time or from time to time pursuant to such instructions as may be described therein authenticate and deliver the Securities of such series. In authenticating the Securities of such series and accepting the additional responsibilities under this Indenture in relation to the Securities of such series, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon: -14- (1) an Officers' Certificate complying with Section 102 and stating to the best knowledge of the signers of such certificate that no Event of Default with respect to any series of Securities shall have occurred and be continuing; and (2) an Opinion of Counsel complying with Section 102 and stating: (a) the form of the Securities of such series have been established in conformity with the provisions of this Indenture; (b) the terms of the Securities of such series have been established (or, when determined in the manner described in such opinion, will have been established) in conformity with the provisions of this Indenture; and (c) that the Securities of such series, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting the enforcement of creditors' rights and to general equity principles. The Trustee shall have the right to decline to authenticate and deliver the Securities of such series if the Trustee, being advised by counsel, determines that such action may not lawfully be taken, would expose the Trustee to personal liability to existing Holders or would add to the obligations and duties of the Trustee hereunder in any material respect. Each Security shall be dated the date of its authentication. No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. SECTION 304. Temporary Securities. -------------------- Pending the preparation of definitive Securities of any series, the Company may execute, and upon compliance with Section 303 the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. -15- If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of the same series of authorized denominations. Such exchange shall be made by the Company at its expense and without any charge therefor. Until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series. SECTION 305. Registration; Registration of Transfer and Exchange. --------------------------------------------------- The Company shall cause to be kept for each series of Securities at one of the offices or agencies maintained pursuant to Section 1002 a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of such Securities and of transfers of such Securities, Said office or agency is hereby appointed "Security Registrar" for the purpose of registering Securities and transfers of Securities as herein provided. Upon surrender for registration of transfer of any Security of any series at the office or agency 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 Securities of the same series and of like tenor, of any authorized denominations and of a like aggregate principal amount and Stated Maturity. In no case shall there be more than one Security Register for a series of Securities. At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series and of like tenor, of any authorized denominations and of a like aggregate principal amount and Stated Maturity, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or his attorney duly authorized in writing. -16- No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. The Company shall not be required (i) to issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before the day of selection of Securities of such series to be redeemed and ending at the close of business on the day of the mailing of a notice of redemption of Securities of such series so selected for redemption, or (ii) to register the transfer of or exchange any Security selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. ------------------------------------------------ If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. -17- The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. SECTION 307. Payment of Interest; Interest Rights Preserved. ---------------------------------------------- Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. At the option of the Company, interest on the Securities of any series that bears interest may be paid by mailing a check to the address of any Holder as such address shall appear in the Securities Register. Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below: (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing as to the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities of such series at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). -18- (2) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee. Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. SECTION 308. Persons Deemed Owners. --------------------- The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 307) interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. SECTION 309. Cancellation. ------------ All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall be destroyed by the Trustee and the Trustee shall deliver to the Company a certificate of destruction in respect thereof. SECTION 310. Computation of Interest. ----------------------- Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. SECTION 311. Automated Issuance System. ------------------------- If the Board Resolution, action pursuant to Board Resolution or supplemental indenture hereto establishing the terms of the Securities of any series shall specify that the automated issuance system described in Section 311 shall be available for the Securities of such series, all issuance instructions for the Securities of such series may be given by an authorized -19- representative of the Company named as such in an Officers' Certificate (an "Authorized Representative") by telephone through computer timesharing entered as prescribed in the user documentation provided by Morgan Guaranty Trust Company of New York as the Company's issuing agent (the "Agent"), such computer timesharing system being herein called the "MPI System" (or telephone or facsimile transmission or other writing, if the MPI System is inoperative). All instructions must be received by the Agent not later than 3:00 P.M. New York City time on the Business Day next preceding the delivery date of each Security and shall include with respect to each Security: (1) name of the Holder; (2) address of the Holder; (3) taxpayer identifying number of the Holder; (4) principal amount; (5) maturity date; (6) interest rate; (7) delivery date; and (8) amount to be received in payment. Upon receipt of such instructions and following authentication of such Securities, the Agent shall deliver such Securities to any placement agent designated by the Company or its designated consignee, which delivery shall be against receipt for payment in immediately available funds, as herein provided, or as otherwise provided in such instructions. Although the Agent may be instructed to deliver Securities against payment in immediately available funds, delivery of the Securities, in accordance with the custom prevailing in the market, will be made before actual receipt of payment. Therefore, once the Agent has delivered Securities to any placement agent or its designated consignee, the Company shall bear the risk that such placement agent or such designated consignee fails to remit payment for the Securities or return same to the Agent. Each delivery of Securities hereunder shall be subject to the rules of the New York Clearing House in effect at the time of such delivery. Telephone instructions given to the Agent will be electronically voice-recorded by the Agent and such recording is hereby consented to. Should any discrepancy develop with respect to such telephonic instructions, the instructions as recorded and understood by the Agent will be deemed the controlling and proper instructions, The Agent shall incur no liability to the Company in acting hereunder upon telephonic or other instructions contemplated hereby which the recipient thereof believed in good faith to have been given by an Authorized Representative. The MPI System timesharing services which may be utilized by the Company and the Agent in the issuance of the Securities and maintenance of the Note Register are furnished to the Agent by -20- The Service Bureau Company, a division of Control Data Corporation ("SBC"). SBC has granted permission to the Agent to allow its clients to use such timesharing services, and in consideration for such permission, it is agreed that, if the Company shall have elected to use the MPI System, such services will be supplied to the Company "as is," without warranty by SBC or the Agent. The Company hereby waives any claims it may have against SBC or the Agent arising out of such timesharing services and agrees that the provisions of Sections 104, 603, 604 and 607 shall inure to the benefit of the Agent to the same extent that they inure to the benefit of the Trustee. ARTICLE FOUR SATISFACTION AND DISCHARGE SECTION 401. Satisfaction and Discharge of Indenture. --------------------------------------- This Indenture shall upon Company Request cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (1) either (A) all Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306 and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or (B) all such Securities not theretofore delivered to the Trustee for cancellation (i) have become due and payable, or (ii) will become due and payable at their Stated Maturity within one year, or (iii) 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 (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose an amount sufficient to pay and discharge the entire indebtedness on such Securities not -21- 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 Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and (3) 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 have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 607 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive. SECTION 402. Application of Trust Money. -------------------------- Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Sections 401 and 403 shall be held in trust and applied by it, in accordance with the provisions of the Securities 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 interest for whose payment such money has been deposited with the Trustee. SECTION 403. Defeasance Upon Deposit of Moneys or Government Obligations. ----------------------------------------------------------- To the extent made applicable to the Securities of any series by the terms thereof established as contemplated in Section 301, at the Company's option, either (a) the Company shall be deemed to have been Discharged (as defined below) from its obligations with respect to the Securities of such series on the 91st day after the applicable conditions set forth below have been satisfied or (b) the Company shall cease to be under any obligation to comply with any term, provision or condition set forth in Sections 801, 802, 1005, 1006 and 1007 and noncompliance with such Sections shall not give rise to any Event of Default under Section 501(4), with respect to the Securities of such series at any time after the applicable conditions set forth below have been satisfied: (1) the Company shall have deposited or caused to be deposited irrevocably with the Trustee or its agent as trust funds in trust, specifically pledged as security for, and dedicated solely to, the benefit of the holders of the Securities of such series (i) money in an amount, or (ii) Government Obligations of the government in the currency of which the Securities of such series are denominated which through the payment of interest and principal in respect thereof in accordance with their terms will provide, not later than the due date of any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient, in the opinion (with respect to (ii) and (iii)) of a -22- nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge each installment of principal (including mandatory sinking fund payments) of, and interest on, the outstanding Securities of such series on the dates such installments of interest or principal are due or to and including the Redemption Date irrevocably designated by the Company pursuant to subparagraph (5) hereof; (2) if the Securities of such series are then listed on the New York Stock Exchange, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the exercise of the option under this Section 403 would not cause such Securities to be delisted; (3) no Event of Default or event which with notice or lapse of time would become an Event of Default under Section 501(l), (2), (3), (5) or (6) with respect to the Securities of such series shall have occurred and be continuing on the date of such deposit; (4) the Company shall have delivered to the Trustee an opinion of counsel, which opinion and counsel are satisfactory to the Trustee and its counsel, to the effect that holders of the Securities of such series will not recognize income, gain or loss for Federal income tax purposes as a result of the exercise of the option under this Section 403 and will be subject to Federal income tax on the same amount and in the same manner and at the same times as would have been the case if such option had not been exercised, and, in the case of Securities being Discharged, and if the Trustee so requests, a private letter ruling to that effect received from the United States Internal Revenue Service or a revenue ruling pertaining to a comparable form of transaction to that effect published by the United States Internal Revenue Service, and (5) if the Company has deposited or caused to be deposited money or Government Obligations to pay or discharge the principal of (and premium, if any) and interest on the Outstanding Securities of a series to and including a Redemption Date pursuant to subparagraph (1) hereof, such Redemption Date shall be irrevocable designated by a Board Resolution delivered to the Trustee on or prior to the date of deposit of such money or Government Obligations, and such Board Resolution shall be accompanied by an irrevocable Company Request that the Trustee give notice of such redemption in the name and at the expense of the Company not less than 30 nor more than 60 days prior to such Redemption Date in accordance with Section 1104.

SECTION 502. Acceleration of Maturity; Rescission and Annulment. -------------------------------------------------- If an Event of Default with respect to Securities of any series at the time outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series established pursuant to Section 301(12)) of all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if -25- (1) the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all overdue interest on all Securities of that series, (B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Securities, (C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and (2) all Events of Default with respect to Securities of that series, other than the nonpayment of the principal of Securities of that series which has become due solely by such declaration of acceleration, have been cured or waived or provided in Section 513.

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. SECTION 504. Trustee May File Proofs of Claim. -------------------------------- In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, (i) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and any predecessor Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee and any predecessor Trustee, their agents and counsel) and of the Holders allowed in such judicial proceeding, and (ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee and any predecessor Trustee any amount due them 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 and any predecessor Trustee under Section 607. -27- Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 507. Limitation on Suits. ------------------- No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (1) an Event of Default with respect to Securities of such series shall have occurred and be continuing and such Holder has previously given written notice to the Trustee of such continuing Event of Default; -28- (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and.

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and ---------------------------------------------------------------- Interest. -------- Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of (and premium, if any) and (subject to Section 307) interest on such Security on the Stated Maturity or Maturities expressed in such Security (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 509. Restoration of Rights and Remedies. ---------------------------------- If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Rights and Remedies Cumulative. ------------------------------ Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted -29- by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. SECTION 511. Delay or Omission Not Waiver. ---------------------------- No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or any acquiescence therein.

The court in which such bankruptcy, receivership or proceedings for reorganization is pending shall have jurisdiction (i) to apportion among the Trustee, the Holders and the holders of other indenture securities, in accordance with the provisions of this paragraph, the funds and property held in such special account and proceeds thereof, or (ii) in lieu of such apportionment, in whole or in part, to give to the provisions of this paragraph due consideration in determining the fairness of the distributions to be made to the Trustee and the Holders and the holders of other indenture securities with respect to their respective claims, in which event it shall not be necessary to liquidate or to appraise the value of any securities or other property held in such special account or as security for any such claim, or to make a specific allocation of such distributions as between the secured and unsecured portions of such claims, or otherwise to apply the provisions of this paragraph as a mathematical formula. Any Trustee which has resigned or been removed after the beginning of such four months' period shall be subject to the provisions of this Subsection as though such resignation or removal had not occurred. If any Trustee has resigned or been removed prior to the beginning of such four months' period, it shall be subject to the provisions of this Subsection if and only if the following conditions exist: (i) the receipt of property or reduction of claim, which would have given rise to the obligation to account, if such Trustee had continued as Trustee, occurred after the beginning of such four months' period; and (ii) such receipt of property or reduction of claim occurred within four months after such resignation or removal.

For all purposes of this Indenture (except in the case of original issuance of the Securities and the issuance of Securities in replacement of lost, stolen, mutilated or destroyed Securities), the authentication and delivery of Securities by an Authenticating Agent appointed pursuant to the provisions of this Section shall be deemed to be the authentication and delivery of such Securities "by the Trustee," and whenever this Indenture provides (except in the case of original issuance of the Securities and the issuance of Securities in replacement of lost, stolen, mutilated or destroyed Securities) that "the Trustee shall authenticate and deliver" Securities, such authentication and delivery by any Authenticating Agent shall be deemed to be authentication and delivery by the Trustee.

If at any time an Authenticating Agent shall cease to be eligible to act as such in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect herein specified in this Section. -47- Any corporation into which any 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 any Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency business of any Authenticating Agent, shall be the successor of the Authenticating Agent hereunder, if such successor corporation is otherwise eligible to act as such in accordance with the provisions of this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent or such successor corporation. Any Authenticating Agent may at any time resign by giving written notice of resignation to the Trustee and to the Company.

Upon receiving such a notice or resignation or upon a termination, or in case at any time any Authenticating Agent shall cease to be eligible to act as such in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent. Upon the appointment, at any time after the original issuance of any of the Securities, of any successor, additional or new Authenticating Agent, the Trustee shall give written notice of such appointment to the Company and shall at the expense of the Company mail notice of such appointment to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, as their names and addresses appear in the Security Register. Any successor Authenticating Agent upon acceptance of its appointment pursuant to the provisions of this Section shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if initially named as an Authenticating Agent herein. No successor Authenticating Agent shall be appointed unless eligible to act as such in accordance with the provisions of this Section.

Any Authenticating Agent by the acceptance of its appointment shall be deemed to have agreed with the Trustee to indemnify the Trustee against any loss, liability or expense incurred by the Trustee and to defend any claim asserted against the Trustee by reason of any acts or failures to act of such Authenticating Agent, but such Authenticating Agent shall have no liability for any action taken by it in accordance with the specific written direction of the Trustee. The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation and expenses for its services (to the extent such compensation is not -48- paid by the Company), and the Trustee shall be entitled to be reimbursed for such payments subject to the provisions of Section 607. The provisions of Sections 104, 603, 604 and 607 shall inure to the benefit of each Authenticating Agent to the same extent that they inure to the benefit of the Trustee.
