(c) The ownership of Debentures shall be proved by the Debentures Register.

(e) The Company may set any day as a record day for the purpose of determining the Holders of Outstanding Debentures entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Debentures, provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next 36 paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding Debentures on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Debentures on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount at maturity of Outstanding Debentures on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder in the manner set forth in Section 106. The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Debentures entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512. If any record date is set pursuant to this paragraph, the Holders of Outstanding Debentures on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount at maturity of Outstanding Debentures on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount at maturity of Outstanding Debentures on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company's expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder in the manner set forth in Section 106. With respect to any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as the "Expiration Date" and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to have 37 initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. (f) Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Debenture may do so with regard to all or any part of the Accreted Value of such Debenture or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such Accreted Value.

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. SECTION 107. CONFLICT WITH TRUST INDENTURE ACT. If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be part of and govern this Indenture, the latter provision shall control.

If in subsequent transfers the Debentures are offered and sold to QIB's in reliance on Rule 144A or in offshore transactions in reliance on Regulation S, the purchasers thereof may exchange such Definitive Debentures for a beneficial interest in a global Debenture in conformity with the customary requirements of The Depository Trust Company (the "Depositary") and registered in the name of the Depositary or its nominee, in each case for credit to an account of a direct or indirect participant in the Depositary. Any such Debenture issued to a QIB shall be represented by one or more Debentures in registered global form without interest coupons (collectively, the "Rule 144A Global Debenture") and any such Debenture issued in connection with offshore transactions in reliance on Regulation S shall, if such Debentures are subject to the restricted period pursuant to Rule 903 (the "restricted period"), be represented by one or more temporary Debentures in registered global form without interest coupons (collectively, the "Regulation S Temporary Global Debenture") and if not so restricted, by one or more permanent registered global Debentures without interest coupons (the "Regulation S Permanent Global Debentures" and together with the Regulation S Temporary Global Debenture, the "Regulation S Global Debenture").

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Debentures 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 such Company Order shall authenticate and deliver such Debentures as in this Indenture provided and not otherwise. Each 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 executed by the Trustee by manual signature, and such certificate upon any Debenture shall be conclusive evidence, and the only evidence, that such Debenture has been duly authenticated and delivered hereunder. 44 SECTION 304. TEMPORARY DEBENTURES. Pending the preparation of Definitive Debentures, 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 and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Debentures may determine, as evidenced by their execution of such Debentures. If temporary Debentures are issued, the Company shall cause Definitive Debentures to be prepared without unreasonable delay. After the preparation of Definitive Debentures, the temporary Debentures shall be exchangeable for Definitive Debentures upon surrender of the temporary Debentures at any office or agency of the Company designated pursuant to Section 1002, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Debentures the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount at maturity of Definitive Debentures of authorized denominations. Until so exchanged the temporary Debentures shall in all respects be entitled to the same benefits under this Indenture as Definitive Debentures. SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 1002 being herein sometimes collectively referred to 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 Trustee is hereby appointed "Debenture Registrar" for the purpose of registering Debentures and transfers of Debentures as herein provided. Upon surrender for registration of transfer of any Debenture at an office or agency of the Company designated pursuant to Section 1002 for such purpose, 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 any authorized denominations and of a like aggregate principal amount at maturity. At the option of the Holder, Debentures may be exchanged for other Debentures of any authorized denominations and of a like aggregate principal amount at maturity, upon surrender of the Debentures to be exchanged at such office or agency. Whenever any 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. 45 All Debentures issued upon any registration of transfer or exchange of Debentures shall be the valid obligation 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 Debenture 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 Debenture Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. (a) TRANSFER AND EXCHANGE OF DEFINITIVE DEBENTURES. When Definitive Debentures are presented to the Debenture Registrar with a request (x) to register the transfer of such Definitive Debentures or (y) to exchange such Definitive Debentures for an equal principal amount at maturity of Definitive Debentures of other authorized denominations, the Debenture Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; PROVIDED, HOWEVER, that the Definitive Debentures surrendered for registration of transfer or exchange: (i) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Debenture Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing; and (ii) in the case of Transfer Restricted Debentures that are Definitive Debentures, shall be accompanied by the following additional information and documents, as applicable: (A) if such Transfer Restricted Debenture is being delivered to the Debenture Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect (in substantially the form set forth on the reverse of the Debenture); or (B) if such Transfer Restricted Debenture is being transferred to a QIB that is aware that any sale of Debentures to it shall be made in reliance on Rule 144A and that is acquiring such Transfer Restricted Debenture for its own account or for the account of another such QIB, a certification from such Holder to that effect (in substantially the form set forth on the reverse of the Debenture); or (C) if such Transfer Restricted Debenture is being transferred pursuant to an exemption from registration in accordance with Rule 144, or 46 outside the United States in an offshore transaction in compliance with Rule 904, or pursuant to an effective registration statement under the Securities Act, a certification from such Holder to that effect (in substantially the form set forth on the reverse of the Debenture); or (D) if such Transfer Restricted Debenture is being transferred in reliance on another exemption from the registration requirements of the Securities Act and with all applicable securities laws of the States of the United States, a certification from such Holder to that effect (in substantially the form set forth on the reverse of the Debenture) and an Opinion of Counsel from the Holder reasonably acceptable to the Company, the Trustee, and to the Debenture Registrar to the effect that such transfer is in compliance with the Securities Act. (b) RESTRICTIONS ON TRANSFER OF A DEFINITIVE DEBENTURE FOR A BENEFICIAL INTEREST IN A GLOBAL DEBENTURE. A Definitive Debenture may not be exchanged for a beneficial interest in a Global Debenture except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Definitive Debenture, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with: (i) if such Definitive Debenture is a Transfer Restricted Debenture, certification, in substantially the form set forth on the reverse of the Debenture, that such Definitive Debenture is being transferred to a QIB in accordance with Rule 144A; and (ii) whether or not such Definitive Debenture is a Transfer Restricted Debenture, written instructions directing the Trustee to make, or to direct the Debentures Custodian to make, an endorsement on the Global Debenture to reflect an increase in the aggregate principal amount at maturity of the Debentures represented by the Global Debenture, then the Trustee shall cancel such Definitive Debenture and cause, or direct the Debentures Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Debentures Custodian, the aggregate principal amount at maturity of Debentures represented by the Global Debenture to be increased accordingly. If no Global Debentures are then outstanding, the Company shall issue and the Trustee shall authenticate a new Global Debenture in the appropriate principal amount. (c) TRANSFER AND EXCHANGE OF GLOBAL DEBENTURES. The transfer and exchange of Global Debentures or beneficial interests therein shall be effected through the Depositary, in accordance with this Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depositary therefor. Except as set forth in clause (d) through (f), a Global Debenture may not be transferred as a whole except by the Depositary to a nominee of the 47 Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. (d) TRANSFER OF A BENEFICIAL INTEREST IN A GLOBAL DEBENTURE FOR A DEFINITIVE DEBENTURE. (i) A Global Debenture is exchangeable for Definitive Debentures in registered certificated form if (A) the Depositary (x) notifies the Company that it is unwilling or unable to continue as depositary for the Global Debenture and the Company thereupon fails to appoint a successor depositary or (y) has ceased to be a clearing agency registered under the Exchange Act, (B) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Debentures in certificated form or (C) there shall have occurred and be continuing an Event of Default or any event which after notice or lapse of time or both would be an Event of Default with respect to the Debentures. In all cases, Definitive Debentures delivered in exchange for any Global Debenture or beneficial interests therein shall be registered in the names, and issued in any approved denominations, requested by or on behalf of the Depositary (in accordance with its customary procedures) and shall bear the applicable restrictive legend, unless the Company determines otherwise in compliance with applicable law. (ii) Upon receipt by the Trustee of written instructions or such other form of instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any Person having a beneficial interest in a Global Debenture, and upon receipt by the Trustee of a written instruction or such other form of instructions as is customary for the Depositary or the Person designated by the Depositary as having such a beneficial interest in a Transfer Restricted Debenture only, and upon receipt of the following additional information and documents (all of which may be submitted by facsimile): (A) if such beneficial interest is being transferred to the Person designated by the Depositary as being the beneficial owner, a certification from the transferor to that effect (in substantially the form set forth on the reverse of the Debenture); or (B) if such beneficial interest is being transferred to a QIB that is aware that any sale of Debentures to it shall be made in reliance on Rule 144A under the Securities Act and that is acquiring such beneficial interest in the Transfer Restricted Debenture for its own account or the account of another such QIB, a certification to that effect from the transferor (in substantially the form set forth on the reverse of the Debenture); or 48 (C) if such beneficial interest is being transferred pursuant to an exemption from registration in accordance with Rule 144, or outside the United States in an offshore transaction in compliance with Rule 904, or pursuant to an effective registration statement under the Securities Act, a certification from the transferor to that effect (in substantially the form set forth on the reverse of the Debenture); or (D) if such beneficial interest is being transferred in reliance on another exemption from the registration requirements of the Securities Act and in accordance with all applicable securities laws of the States of the United States, a certification to that effect from the transferor (in substantially the form set forth on the reverse of the Debenture) and an Opinion of Counsel from the transferee or transferor reasonably acceptable to the Company and to the Debenture Registrar to the effect that such transfer is in compliance with the Securities Act, then the Trustee shall cause, or direct the Debentures Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Debentures Custodian, the aggregate principal amount at maturity of the Global Debenture to be reduced accordingly and, following such reduction, the Company shall execute and, upon receipt of a Company Order, the Trustee shall authenticate and deliver to the transferee a Definitive Debenture in the appropriate principal amount. (e) EXCHANGES BETWEEN REGULATION S GLOBAL DEBENTURES AND RULE 144A GLOBAL DEBENTURES. Prior to the expiration of any restricted period, beneficial interests in the Regulation S Temporary Global Debenture may not be transferred to a Person who takes delivery in the form of an interest in a Rule 144A Global Debenture. After the expiration of the restricted period, beneficial interests in Regulation S Permanent Global Debentures may be transferred to a Person who takes delivery in the form of an interest in a Rule 144A Global Debenture. Upon receipt by the Trustee of written instructions or such other form of instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any Person having a beneficial interest in the Regulation S Permanent Global Debenture, then the Trustee shall cause, or direct the Debentures Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Debentures Custodian, the aggregate principal amount at maturity of the Regulation S Permanent Global Debenture to be decreased and the aggregate principal amount at maturity of the Rule 144A Global Debenture to be increased by the principal amount at maturity of the beneficial interest in the Regulation S Permanent Global Debenture to be exchanged, to credit, or cause to be credited, to the account of the transferor a beneficial interest in the Rule 144A Global Debenture equal to the reduction in the aggregate principal amount at maturity of the Regulation S Permanent Global Debenture, and to debit, or cause to be debited, from the account of the transferor the beneficial interest in the Regulation S Permanent Global Debenture that is being exchanged or transferred. 49 Prior to the expiration of any restricted period, beneficial interests in the Rule 144A Global Debenture may not be transferred to any Person that takes delivery thereof in the form of an interest in the Regulation S Temporary Global Debenture. After the expiration of such restricted period, beneficial interests in the Rule 144A Global Debenture may be transferred to a Person who takes delivery in the form of an interest in the Regulation S Permanent Global Debenture only upon receipt by the Trustee of a written certification from the transferor to the effect that such transfer is being made in accordance with Rule 904. Upon receipt by the Trustee of written instructions or such other form of instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any Person having a beneficial interest in the Rule 144A Global Debenture, then the Trustee shall cause, or direct the Debentures Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Debentures Custodian, the aggregate principal amount at maturity of the Rule 144A Global Debenture to be decreased and the aggregate principal amount of the Regulation S Permanent Global Debenture to be increased by the principal amount at maturity of the beneficial interest in the Rule 144A Global Debenture to be exchanged, to credit, or cause to be credited, to the account of the transferor a beneficial interest in the Regulation S Permanent Global Debenture equal to the reduction in the aggregate principal amount at maturity of the Rule 144A Global Debenture, and to debit, or cause to be debited, from the account of the transferor the beneficial interest in the Rule 144A Global Debenture that is being exchanged or transferred.

(j) CANCELLATION AND/OR ADJUSTMENT OF GLOBAL DEBENTURE. At such time as all beneficial interests in a Global Debenture have either been exchanged for Definitive Debentures or beneficial interests in other Global Debentures, redeemed, repurchased or canceled, such Global Debenture shall be returned to or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Debenture is exchanged for Definitive Debentures or a beneficial interest in another Global Debenture, redeemed, repurchased or canceled, the principal amount at maturity of Debentures represented by such Global Debenture shall be reduced and an endorsement shall be made on such Global Debenture, by the Trustee or the Debentures Custodian, at the direction of the Trustee, to reflect such reduction.

To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Definitive Debentures and Global Debentures at the Debenture Registrar's request. (l) GENERAL. 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 304, 906 or 1108 or in accordance with any Asset Sale Offer or Change of Control Offer pursuant to Section 1015 or 1014, respectively, not involving any transfer. The Company shall not be required (i) to issue, register the transfer of or exchange any Debenture during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Debentures selected for redemption under Section 1104 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or 53 exchange any Debenture so selected for redemption in whole or in part, except the unredeemed portion of any Debenture being redeemed in part. SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN DEBENTURES. If any mutilated Debenture is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Debenture of like tenor and principal amount at maturity 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 Debenture 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 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 like tenor and principal amount at maturity and bearing a number not contemporaneously outstanding. 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, pay such Debenture. Upon the issuance of any new Debenture 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 Debenture issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Debenture shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, 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 duly issued hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debentures. 54 SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED. Interest on any Debenture 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 Debenture (or one or more Predecessor Debentures) is registered at the close of business on the Regular Record Date immediately preceding such Interest Payment Date. Any interest on any Debenture 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 Debentures (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 Debenture 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 at his address as it appears in the Debenture 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 Debentures (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 (2). (2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the 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 of the proposed payment 55 pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. Subject to the foregoing provisions of this Section, 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 308. PERSONS DEEMED OWNERS. Prior to due presentment of a 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 Debenture is registered as the owner of such Debenture for the purpose of receiving payment of Accreted Value of (and premium, if any) and (subject to Section 307) interest on such Debenture and for all other purposes whatsoever, whether or not such 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. SECTION 309. CANCELLATION. All Debentures surrendered for payment, redemption, registration of transfer or exchange or any Asset Sale Offer or Change of Control Offer pursuant to Section 1015 or 1014, respectively 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 Debentures previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Debentures so delivered shall be promptly canceled by the Trustee. No Debentures shall be authenticated in lieu of or in exchange for any Debentures canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Debentures held by the Trustee shall be disposed of as directed by a Company Order. SECTION 310. COMPUTATION OF INTEREST. Interest on the Debentures shall be computed on the basis of a 360-day year of twelve 30-day months. SECTION 311. CUSIP AND ISIN NUMBERS. 56 The Company in issuing Debentures may use "CUSIP" and "ISIN" numbers (if then generally in use) in addition to serial numbers; if so, the Trustee shall use such "CUSIP" and "ISIN" numbers in addition to serial numbers in notices of redemption and repurchase as a convenience to Holders; PROVIDED that any such notice may state that no representation is made as to the correctness of such CUSIP and ISIN numbers either as printed on the Debentures or as contained in any notice of a redemption or repurchase and that reliance may be placed only on the serial or other identification numbers printed on the Debentures, and any such redemption or repurchase shall not be affected by any defect in or omission of such CUSIP and ISIN numbers. ARTICLE FOUR Satisfaction and Discharge SECTION 401. SATISFACTION AND DISCHARGE OF INDENTURE. This Indenture shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Debentures herein expressly provided for), and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (1) either (A) all Debentures theretofore authenticated and delivered (other than (i) Debentures which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306 and (ii) Debentures 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 Debentures not theretofore delivered to the Trustee for cancellation (i) have become due and payable, or (ii) shall 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 57 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 an amount sufficient to pay and discharge the entire indebtedness on such Debentures not theretofore delivered to the Trustee for cancellation, for Accreted Value (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; (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, the provisions of Sections 303, 305 and 306 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 Section 401 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 Accreted Value (and premium, if any) and interest for whose payment such money has been deposited with the Trustee. 58 ARTICLE FIVE Remedies SECTION 501.

(5) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for borrowed money or Guarantee by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the Issue Date, if that default: (a) is caused by a failure to pay principal of or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a "Payment Default"); or (b) results in the acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which 59 there has been a Payment Default or the maturity of which has been so accelerated, aggregates $20 million or more; (6) failure by the Company or any of its Restricted Subsidiaries to pay final judgments aggregating in excess of $20 million, which judgments are not paid, discharged or stayed for a period of 60 days after the entry of such judgment or judgments;

and (8) the commencement by the Company or any of its Restricted Subsidiaries that are Significant Subsidiaries of the Company of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company or any such Subsidiary to the entry of a decree or order for relief in respect of the Company or any of its Restricted Subsidiaries that are Significant Subsidiaries of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company or any such Subsidiary of the Company, or the filing by the Company or any such Subsidiary of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by the Company or any such Subsidiary to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or similar official of the Company or any of its Restricted Subsidiaries that are Significant Subsidiaries of the Company or of any substantial part of the property of the Company or any of its Restricted 60 Subsidiaries that are Significant Subsidiaries of the Company, or the making by the Company or any of its Restricted Subsidiaries that are Significant Subsidiaries of the Company of an assignment for the benefit of creditors, or the admission by the Company or any such Subsidiary in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any such Significant Subsidiary in furtherance of any such action. Notwithstanding any provision herein to the contrary, the nonpayment of any amounts required to be paid by the Company pursuant to Section 301(c) shall not constitute a Default or an Event of Default; PROVIDED HOWEVER that during any period of any such nonpayment the Debentures shall accrue interest at the rate borne by the Debentures plus 1% per annum. In the event of a declaration of acceleration of the Debentures because an Event of Default has occurred and is continuing as a result of the acceleration of any Indebtedness described in clause (5) of this Section 501, the declaration of acceleration of the Debentures shall be automatically annulled if the holders of any Indebtedness described in clause (5) of this Section 501 have rescinded the declaration of acceleration in respect of such Indebtedness within 30 days of the date of such declaration and if: (a) the annulment of the acceleration of Debentures would not conflict with any judgment or decree of a court of competent jurisdiction; and (b) all existing Events of Default, except nonpayment of Accreted Value or interest on the Debentures that became due solely because of the acceleration of the Debentures, have been cured or waived. SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount at maturity of the Outstanding Debentures may declare all of the Debentures to be due and payable immediately in an amount equal to (x) the Accreted Value of the Debentures outstanding on the date of acceleration, if such declaration is made prior to the Full Accretion Date or (y) the entire principal amount at maturity of all the Debentures outstanding on the date of acceleration plus accrued interest, if any, to the date of acceleration if such declaration is made after the Full Accretion Date. Notwithstanding the preceding paragraph, in the case of an Event of Default described in clause (7) or (8) of Section 501, with respect to the Company or any of its 61 Subsidiaries, all Outstanding Debentures shall become due and payable immediately without further action or notice in an amount equal to (x) the Accreted Value of the Debentures outstanding on the date of acceleration, if such declaration is made prior to the Full Accretion Date or (y) the entire principal amount at maturity of all the Debentures outstanding on the date of acceleration plus accrued interest, if any, to the date of acceleration if such declaration is made after the Full Accretion Date. In the case any Event of Default occurs by reason of any willful action or inaction taken or not taken by or on behalf of the Company with the intention of avoiding payment of the premium that the Company would have had to pay if the Company then had elected to redeem the Debentures pursuant to Section 1101 hereof, an equivalent premium shall also become and be immediately due and payable to the extent permitted by law upon the acceleration of the Debentures. At any time after such a declaration of acceleration 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 aggregate principal amount at maturity of the Outstanding Debentures, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if the Company has paid or deposited with the Trustee a sum sufficient to pay and except on default with respect to any provision requiring a supermajority approval to amend, which may only be waived by such supermajority, all existing Events of Default, other than the non-payment of the Accreted Value of, premium, if any, and interest on the Debentures which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. No such rescission shall affect any subsequent Default or impair any right consequent thereon. SECTION 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE. Subject to the second paragraph of Section 501, the Company covenants that if (1) default is made in the payment of any interest on any Debenture when such interest becomes due and payable and such default continues for a period of 30 days, or (2) default is made in the payment of the Accreted Value of (or premium, if any, on) any Debenture at the Maturity thereof or, with respect to any Debenture required to have been purchased pursuant to an Asset Sale Offer or Change of Control Offer made by the Company, at the Purchase Date thereof, 62 the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Debentures, the whole amount then due and payable on such Debentures for Accreted Value (and premium, if any) and, if after the Full Accretion Date, interest, and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and on any overdue interest, at the rate provided by the 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, 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 the Debentures 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 the Debentures, wherever situated. If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such judicial proceedings as the Trustee shall deem appropriate, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. SECTION 504. TRUSTEE MAY FILE PROOFS OF CLAIM. In case of any judicial proceeding relative to the Company (or any other obligor upon the Debentures), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized and directed by each Holder to make such payments to the Trustee and, in the event that the Trustee requests the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. No provision of this Indenture 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 Debentures 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, PROVIDED, HOWEVER, that the Trustee may, on behalf of the Holders, vote for the 63 election of a Trustee in bankruptcy or similar official and be a member of a creditors' or other similar committee. SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF DEBENTURES. All rights of action and claims under this Indenture or 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, 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 506. APPLICATION OF MONEY COLLECTED. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of Accreted Value (or premium, if any) or interest, upon presentation of the Debentures and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: FIRST: To the payment of all amounts due the Trustee under Section 607; SECOND: To the payment of the amounts then due and unpaid for Accreted Value of (and premium, if any) and, if after the Full Accretion Date, interest on the Debentures in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Debentures for Accreted Value (and premium, if any) and, if after the Full Accretion Date, interest, respectively; and THIRD: The balance, if any, to the Company. SECTION 507. LIMITATION ON SUITS. No Holder of any Debenture 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 64 (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default; (2) the Holders of not less than 25% in principal amount at maturity of the Outstanding Debentures 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 indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request; (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount at maturity of the Outstanding Debentures; it being understood and intended that no one or more 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 Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders. SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE ACCRETED VALUE, PREMIUM AND INTEREST. Notwithstanding any other provision in this Indenture, the Holder of any Debenture shall have the right, which is absolute and unconditional, to receive payment of the Accreted Value of (and premium, if any) and (subject to Section 307) interest on such Debenture on the respective Stated Maturities expressed in such Debenture (or, in the case of redemption, on the Redemption Date or in the case of an Asset Sale Offer or Change of Control Offer made by the Company and required to be accepted as to such Debenture, on the Purchase 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. 65 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. SECTION 510. 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 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. SECTION 511. DELAY OR OMISSION NOT WAIVER. No delay or omission of the Trustee or of any Holder of any 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 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. SECTION 512. CONTROL BY HOLDERS. The Holders of a majority in aggregate principal amount at maturity of the Outstanding Debentures 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, PROVIDED that (1) such direction shall not be in conflict with any rule of law or with this Indenture or involve the Trustee in personal liability, and 66 (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. SECTION 513. WAIVER OF PAST DEFAULTS. The Holders of not less than a majority in aggregate principal amount at maturity of the Outstanding Debentures may on behalf of the Holders of all the Debentures waive any existing Default hereunder and its consequences, except a default with respect to any provision requiring a supermajority to amend, which default may only be waived by such a supermajority, except a Default (1) in the payment of the Accreted Value of (or premium, if any) or interest on any Debenture (including any Debenture which is required to have been purchased pursuant to an Asset Sale Offer or Change of Control Offer which has been made by the Company), or (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Debenture 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 impair any right consequent thereon. SECTION 514. UNDERTAKING FOR COSTS. In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs, including reasonable attorney's fees and expenses, against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; PROVIDED, that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Trustee or the Company. 67 SECTION 515. WAIVER OF USURY, STAY OR EXTENSION LAWS. The Company covenants (to the extent that it may lawfully do so) that it shall 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 shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted. ARTICLE SIX The Trustee SECTION 601. CERTAIN DUTIES AND RESPONSIBILITIES. (a) The duties and responsibilities of the Trustee shall be as provided by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee 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.

Subject to the provisions of Section 601: (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, note, other evidence of indebtedness 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 and any resolution of the Board of Directors of the Company 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 69 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 powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity 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, note, other evidence of indebtedness or other paper or document, but 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, upon reasonable prior notice, to examine the books, records and premises of the Company, personally or by agent or attorney at such reasonable times as reasonably requested; and (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. SECTION 604. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF DEBENTURES. The recitals contained herein and in the Debentures, except the Trustee's certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Debentures. The Trustee shall not be accountable for the use or application by the Company of the Debentures or the proceeds thereof. SECTION 605. MAY HOLD DEBENTURES. 70 The Trustee, any Paying Agent, any Debenture Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Debentures and, subject to Sections 608 and 613, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Paying Agent, Debenture Registrar or such other agent.

The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. 71 To secure the Company's payment obligations in this Section 607, the Trustee shall have a lien prior to the Debentures on all assets held or collected by the Trustee, in its capacity as Trustee, except assets held in trust to pay principal of or interest on particular Debentures. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 501(8) or (9) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. SECTION 608. DISQUALIFICATION; CONFLICTING INTERESTS. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall eliminate such conflict within 90 days, apply to the Commission for permission to continue or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person 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, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. SECTION 610. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR. (a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee under Section 611.

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 of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee. 72 (c) The Trustee may be removed at any time by Act of the Holders of a majority in principal amount at maturity of the Outstanding Debentures, delivered to the Trustee and 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 of removal, the Trustee being removed may petition any court of competent jurisdiction for the appointment of a Trustee.

(e) 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, the Company, by a Board Resolution, shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount at maturity of the Outstanding Debentures 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 and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner hereinafter provided, any Holder 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. (f) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders in the manner provided in Section 106. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. 73 SECTION 611. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. Every successor Trustee appointed hereunder 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. 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. No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. SECTION 612. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any 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. SECTION 613. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

The Board of Directors' determination must be based upon an opinion or appraisal issued by an accounting, appraisal or investment banking firm of national standing if such fair market value exceeds $20 million. Not later than the date of making any Restricted Payment, the Company shall deliver to the Trustee an Officers' Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this Section 1009 were computed, together with a copy of any fairness opinion or appraisal required by this Indenture. SECTION 1010. LIMITATIONS ON DIVIDENDS AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED SUBSIDIARIES. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to: 93 (1) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries (i) on its Capital Stock or (ii) with respect to any other interest or participation in, or measured by, its profits; (2) pay any Indebtedness owed to the Company or any of the Company's Restricted Subsidiaries; (3) make loans or advances to the Company or any of the Company's Restricted Subsidiaries; or (4) transfer any of its properties or assets to the Company or any of the Company's Restricted Subsidiaries. However, the preceding restrictions shall not apply to encumbrances or restrictions existing under or by reason of: (1) any encumbrance or restriction pursuant to an agreement in effect at or entered into on the Issue Date, including: (a) the Senior Credit Facilities as in effect as of the Issue Date, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof, provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive, taken as a whole (as determined in the good faith judgment of the Company's Board of Directors), with respect to such dividend and other payment restrictions than those contained in the Senior Credit Facilities as in effect on the Issue Date; (b) this Indenture and the Debentures; and (c) the Senior Subordinated Notes; (2) any applicable law, rule, regulation or order; (3) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so 94 acquired, PROVIDED THAT, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred; (4) customary non-assignment provisions in leases entered into in the ordinary course of business and consistent with past practices; (5) any Purchase Money Note or other Indebtedness or contractual requirements incurred with respect to a Qualified Receiveables Transaction relating exclusively to a Receiveables Entity that, in the good faith determination of the Board of Directors of the Company, are necessary to effect such Qualified Receiveables Transaction; (6) purchase money obligations for property acquired in the ordinary course of business that impose restrictions on the property so acquired of the nature described in the last clause of the preceding paragraph; (7) restrictions with respect solely to a Restricted Subsidiary of the Company imposed pursuant to a binding agreement which has been entered into for the sale or disposition of all or substantially all of the Capital Stock or assets of such Restricted Subsidiary, provided that such restrictions apply solely to the Capital Stock or assets being sold of such Restricted Subsidiary; (8) provisions with respect to the disposition or distribution of assets or property in connection with Permitted Joint Ventures entered into in accordance with past practice made in the ordinary course of business; (9) Permitted Refinancing Indebtedness, provided that the material restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive, in the good faith judgment of the Company's Board of Directors, taken as a whole, to the Holders than those contained in the agreements governing the Indebtedness being refinanced; and (10) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business. Notwithstanding the foregoing, neither (a) customary provisions restricting subletting or assignment of any lease entered into in the ordinary course of business, consistent with industry practice, nor (b) Liens permitted under the terms of this Indenture shall in and of themselves be considered a restriction on the ability of the applicable Restricted Subsidiary to transfer such agreement or assets, as the case may be. 95 SECTION 1011. LIMITATION ON LIENS SECURING INDEBTEDNESS. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind securing trade payables, Attributable Debt or Indebtedness (other than Permitted Liens) upon any of their property or assets, now owned or hereafter acquired unless: (1) in the case of Liens securing Indebtedness that is expressly subordinated or junior in right of payment to the Debentures, the Debentures are secured on a senior basis to the obligations so secured until such time as such obligations are no longer secured by a Lien; and (2) in all other cases, the Debentures are secured on an equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien. SECTION 1012. LIMITATION ON TRANSACTIONS WITH AFFILIATES. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate or any affiliated professional associations or professional corporations which employ physicians and other professionals who provide healthcare services for the Company's occupational and health services centers (each, an "Affiliate Transaction"), unless: (1) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary made on an arm's-length basis with an unrelated Person; and (2) the Company delivers to the Trustee: (a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $5 million, a resolution of the Board of Directors of the Company set forth in an Officers' Certificate certifying that such Affiliate Transaction complies with clause (1) above and that such 96 Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors; and (b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $15 million, an opinion as to the fairness to the Holders of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing.

No payments of Affiliate Management Fees shall be made by the Company or any of its Restricted Subsidiaries if the Fixed Charge Coverage Ratio for the Company's most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which Affiliate Management Fees are to be paid is less than 1.5 to 1; PROVIDED, HOWEVER, that such payments due but not paid shall accrue and shall be paid only after such time as the Fixed Charge Coverage Ratio for a four full fiscal quarter period is no longer less than or equal to 1.5 to 1. 98 SECTION 1013. LIMITATION ON ISSUANCES AND SALES OF EQUITY INTERESTS IN RESTRICTED SUBSIDIARIES. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, transfer, convey, sell, lease or otherwise dispose of any Equity Interests in any Restricted Subsidiary or to issue any of its Equity Interests (other than, if necessary, Equity Interests constituting directors' qualifying shares) to any Person except: (1) to the Company or a Wholly Owned Subsidiary (other than a Receivables Entity); or (2) in compliance with Section 1015 and immediately after giving effect to such issuance or sale, such Restricted Subsidiary would continue to be a Restricted Subsidiary. Notwithstanding the preceding paragraph, the Company may sell all the Equity Interests of a Restricted Subsidiary as long as the Company complies with Section 1015. SECTION 1014. REPURCHASE OF DEBENTURES AT THE OPTION OF THE HOLDER UPON A CHANGE OF CONTROL. (1) Upon the occurrence of a Change of Control, each Holder shall have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder's Debentures pursuant to the offer described below (the "Change of Control Offer") at an offer price in cash equal to 101% of the Accreted Value thereof on any Redemption Date plus, after the Full Accretion Date, accrued and unpaid interest thereon, if any, to the Purchase Date (the "Change of Control Payment").

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Debentures as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture relating to such Change of Control Offer, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof. (2) By 12:00 p.m. (noon) Eastern Time on the Purchase Date, the Company shall, to the extent lawful: (a) accept for payment all Debentures or portions thereof properly tendered pursuant to the Change of Control Offer; (b) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Debentures or portions thereof so tendered; and (c) deliver or cause to be delivered to the Trustee the Debentures so accepted together with an Officers' Certificate stating the aggregate Accreted Value of Debentures or portions thereof being purchased by the Company. 100 The Paying Agent shall promptly mail to each Holder of Debentures so tendered the Change of Control Payment for such Debentures, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Debenture equal in principal amount at maturity to any unpurchased portion of the Debentures surrendered, if any; provided that each such new Debenture shall be in a principal amount at maturity of $1,000 or an integral multiple thereof. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Purchase Date. (3) Prior to making a Change of Control Offer pursuant to paragraph (a), but in any event within 90 days following such Change of Control, the Company shall (i) obtain any required consents, if any, under all agreements governing outstanding Senior Indebtedness to permit the making of the Change of Control Offer and the purchase of Debentures pursuant to this Section 1014, or (ii) repay all or a portion of the outstanding Senior Indebtedness to the extent necessary (including, if necessary, payment in full of such Senior Indebtedness and payment of any prepayment premiums, fees, expenses or penalties) to permit the repurchase of the Notes pursuant to this Section 1015 without such consent. (4) Notwithstanding anything to the contrary in this Section 1014, the Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 1014 hereof and all other provisions of this Indenture applicable to a Change of Control Offer made by the Company and purchases all Debentures validly tendered and not withdrawn under such Change of Control Offer. SECTION 1015. REPURCHASE OF DEBENTURES AT THE OPTION OF THE HOLDER UPON AN ASSET SALE. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: (1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of; (2) such fair market value is determined by the Company's Board of Directors and evidenced by a resolution of the Board of Directors set forth in an Officers' Certificate delivered to the Trustee provided that the Board of Directors' determination must be based on an opinion or appraisal issued by an accounting, appraisal or investment banking firm of national standing if such fair market value exceeds $35 million; and 101 (3) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash: (a) any liabilities (as shown on the Company's or the Restricted Subsidiary's most recent balance sheet) of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Debentures, that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability; and (b) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are contemporaneously (subject to ordinary settlement periods) converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents (to the extent of the cash received in that conversion). The 75% limitation referred to above shall not apply to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the preceding sentence, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the 75% limitation. Within 270 days after the receipt of any Net Proceeds from an Asset Sale, the Company or any such Restricted Subsidiary may apply such Net Proceeds, at its option: (1) to repay or repurchase Senior Indebtedness of the Company or Indebtedness of any Restricted Subsidiary; (2) to acquire all or substantially all the assets of, or a majority of the Voting Stock of, another Permitted Business; (3) to make a capital expenditure in a Permitted Business; (4) to acquire other assets (other than securities) that are used or useful in a Permitted Business; or (5) to make an Asset Sale Offer, treating the Net Proceeds as Excess Proceeds for all purposes. 102 Any Net Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph shall constitute "Excess Proceeds". When the aggregate amount of Excess Proceeds exceeds $15 million, the Company shall be required to make an offer to all Holders of Debentures (an "Asset Sale Offer") to purchase the maximum Accreted Value of Debentures that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer shall be equal to 100% of the Accreted Value thereof on any Redemption Date plus, after the Full Accretion Date, accrued and unpaid interest, if any, to the Purchase Date, and shall be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for general corporate purposes. If the aggregate Accreted Value of Debentures tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Debentures to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture relating to such Asset Sale Offer, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

SECTION 1019. DESIGNATION OF RESTRICTED AND UNRESTRICTED SUBSIDIARIES. The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, all outstanding Investments owned by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated shall be deemed to be Restricted Payments at the time of such designation (to the extent not designated a Permitted Investment) and shall reduce the amount available for Restricted Payments under the first paragraph of Section 1009. All such outstanding Investments shall be valued at their fair market value at the time of such designation, as determined in good faith by the Board of Directors of the Company. That designation shall only be permitted if such Restricted Payment would be permitted at that time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors of the Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default. SECTION 1020. ADVANCES OF SUBSIDIARIES. All advances to Restricted Subsidiaries made by the Company after the Issue Date shall be evidenced by intercompany notes in favor of the Company in the form of Exhibit C. Each intercompany note shall be payable upon demand and shall bear interest at the same rate as the Debentures. 104 SECTION 1021. PAYMENTS FOR CONSENTS. The Company shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Debentures unless such consideration is offered to be paid and is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

(b) The Company shall deliver to the Trustee, as soon as possible and in any event within 10 days after the Company becomes aware or should reasonably become aware of the occurrence of a Default or an Event of Default, an Officers' Certificate setting forth the details of such Default or Event of Default, and the action which the Company proposes to take with respect thereto.

WAIVER OF COVENANTS.

SECTION 1206. REINSTATEMENT. If the Trustee or the Paying Agent is unable to apply any money in accordance with Section 1202 or 1203 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, or if a Default from a bankruptcy or insolvency event occurs at any time during the period ending on the 91st day after the date of a deposit by the Company hereunder, then the Company's obligations under this Indenture and the Debentures shall be revived and reinstated as though no deposit had occurred pursuant to this Article Twelve until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 1202 or 1203; PROVIDED, HOWEVER, that if the Company makes any payment of Accreted Value of (and premium, if any) or interest on any Debenture following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Debentures to receive such payment from the money held by the Trustee or the Paying Agent. 113 This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.
