Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

If not set by the Company prior to the first solicitation of a Holder made by any Person in respect of any such matter referred to in the foregoing sentence, the record date for any such matter shall be the 30th day (or, if later, the date of the most recent list of Holders required to be provided pursuant to Section 701) prior to such first solicitation. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities 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 Securities on such record date. Nothing in this paragraph shall be construed to prevent the Company 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 cancelled 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 of Outstanding Securities 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 of Securities in the manner set forth in Section 106.

If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities 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 of Outstanding Securities on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record -29- 41 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 cancelled 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 of Outstanding Securities 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 of Securities 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 of Securities 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 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. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date. Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security 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 principal amount.

SECTION 106. Notice to Holders; Waiver. Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if (i) in the case of a Global Security, in writing by facsimile and/or by overnight mail to the Depositary, and (ii) in the case of securities other than Global Securities, in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. 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. Application of Trust Indenture Act. The Trust Indenture Act shall apply as a matter of contract to this Indenture for purposes of interpretation, construction and defining the rights and obligations hereunder. If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be. -31- 43 SECTION 108.

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 (subject to the provisions in the Original Securities regarding the payment of Additional Interest) 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. 60 No service charge shall be made to the Holder 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, 305, 906 or 1108 or in accordance with any Offer to Purchase pursuant to Section 1013 or 1016 not involving any transfer.

Notwithstanding any other provision of this Indenture or the Securities, transfers and exchanges of Securities and beneficial interests in a Global Security of the kinds specified in this Section 305(b) shall be made only in accordance with this Section 305(b). (i) Restricted Global Security to Regulation S Global Security. If the owner of a beneficial interest in the Restricted Global Security wishes at any time to transfer such interest to a Person who wishes to acquire the same in the form of a beneficial interest in the Regulation S Global Security, such transfer may be effected only in accordance with the provisions of this Clause (b)(i) and Clause (b)(iv) below and subject to the Applicable Procedures. Upon receipt by the Trustee, as Security Registrar, of (A) an order given by the Depositary or its authorized representative directing that a beneficial interest in the Regulation S Global Security in a specified principal amount be credited to a specified Agent Member's account and that a beneficial interest in the Restricted Global Security in an equal principal amount be debited from another specified Agent Member's account and (B) a Regulation S Certificate, satisfactory to the Trustee and duly executed by the owner of such beneficial interest in the Restricted Global Security or his attorney duly authorized in writing, then the Trustee, as Security Registrar but subject to Clause (b)(vii) below, shall reduce the principal amount of the Restricted Global Security and increase the principal amount of the Regulation S Global Security by such specified principal amount. (ii) Regulation S Global Security to Restricted Global Security. If the owner of a beneficial interest in the Regulation S Global Security wishes at any time to transfer such interest to a Person who -49- 61 wishes to acquire the same in the form of a beneficial interest in the Restricted Global Security, such transfer may be effected only in accordance with this Clause (b)(ii) and subject to the Applicable Procedures. Upon receipt by the Trustee, as Security Registrar, of (A) an order given by the Depositary or its authorized representative directing that a beneficial interest in the Restricted Global Security in a specified principal amount be credited to a specified Agent Member's account and that a beneficial interest in the Regulation S Global Security in an equal principal amount be debited from another specified Agent Member's account and (B) if such transfer is to occur during the Restricted Period, a Restricted Securities Certificate, satisfactory to the Trustee and duly executed by the owner of such beneficial interest in the Regulation S Global Security or his attorney duly authorized in writing, then the Trustee, as Security Registrar, shall reduce the principal amount of the Regulation S Global Security and increase the principal amount of the Restricted Global Security by such specified principal amount. (iii) Non-Global Security to Non-Global Security. A Security that is not a Global Security may be transferred, in whole or in part, to a Person who takes delivery in the form of another Security that is not a Global Security as provided in Section 305(a), provided that, if the Security to be transferred in whole or in part is a Restricted Security, or is a Regulation S Security and the transfer is to occur during the Restricted Period, then the Trustee shall have received (A) a Restricted Securities Certificate, satisfactory to the Trustee and duly executed by the transferor Holder or his attorney duly authorized in writing, in which case the transferee Holder shall take delivery in the form of a Restricted Security, or (B) a Regulation S Certificate, satisfactory to the Trustee and duly executed by the transferor Holder or his attorney duly authorized in writing, in which case the transferee Holder shall take delivery in the form of a Regulation S Security (subject in every case to Section 305(c)). (iv) Regulation S Global Security to be Held Through Euroclear or Cedel during Restricted Period. The Company shall use its best efforts to cause the Depositary to ensure that, until the expiration of the Restricted Period, beneficial interests in the Regulation S Global Security may be held only in or through accounts maintained at the Depositary by Euroclear or Cedel (or by Agent Members acting for the account thereof), and no person shall be entitled to effect any transfer or exchange that would result in any such interest being held otherwise than in or through such an account; provided that this Clause (b)(iv) shall not prohibit any transfer or exchange of such an interest in accordance with Clause (b)(ii) above. 62 (v) Exchanges of Book-Entry Securities for Certificated Securities. A beneficial interest in a Global Security may not be exchanged for a Security in certificated form unless (i) DTC (x) notifies the Company that it is unwilling or unable to continue as Depositary for the Global Security or (y) has ceased to be a clearing agency registered under the Exchange Act and in either case the Company thereupon fails to appoint a successor Depositary, (ii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Securities in certificated form or (iii) 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 Securities. In all cases, certificated Securities delivered in exchange for any Global Security or beneficial interests therein will 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). Any certificated Security issued in exchange for an interest in a Global Security will bear the legend restricting transfers that is borne by such Global Security. Any such exchange will be effected through the DWAC System and an appropriate adjustment will be made in the records of the Security Registrar to reflect a decrease in the principal amount of the relevant Global Security.

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 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 the Trustee shall authenticate and 64 deliver, in lieu of any such destroyed, lost or stolen Security, a new Security 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 the discretion of the Company 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 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 duly issued hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. SECTION 307. Payment of Interest; Interest Rights Preserved. Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. Any interest (including Additional Interest) on any Security which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall (a) bear interest at the rate per annum stated in the form of Security included herein (to the extent that the payment of such interest shall be legally enforceable), and (b) 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 (or their respective Predecessor Securities) are -53- 65 registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security 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 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 (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). (2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the 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 66 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. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and premium, if any, and (subject to Section 307) interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and none of the Company, the Trustee or 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, exchange or pursuant to any Offer to Purchase pursuant to Section 1013 or 1016 shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of in accordance with its standard procedures or as directed by a Company Order; provided, however, that the Trustee shall not be required to destroy such Securities. SECTION 310. Computation of Interest. Interest on the Securities shall be computed on the basis of a 360day year of twelve 30-day months, except that Additional Interest shall be computed on the basis of a 365-day year. -55- 67 SECTION 311. CUSIP and ISIN Numbers. The Company in issuing Securities 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 Securities 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 Securities, 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 as to all outstanding Securities (except as to (i) rights of registration of transfer and exchange and the Company's right of optional redemption, (ii) substitution of apparently mutilated, defaced, destroyed, lost or stolen Securities, (iii) rights of holders of Securities to receive payment of principal of and premium, if any, and interest on the Securities, (iv) rights, obligations and immunities of the Trustee under the Indenture and (v) rights of the holders of the Securities as beneficiaries of the Indenture with respect to any property deposited with the Trustee payable to all or any of them), 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) the Company will have paid or caused to be paid the principal of and premium, if any, and interest on the Securities as and when the same will have become due and payable; or (B) all outstanding Securities (except lost, stolen or destroyed Securities which have been replaced or paid) have been delivered to the Trustee for cancellation; and the Company, in the case of (A) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for 68 the purpose an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal of 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; (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; and (4) the Trustee shall have received such other documents and assurances as the Trustee shall have reasonably requested. Notwithstanding the satisfaction and discharge of this Indenture, (i) the obligations of the Company to the Trustee under Section 607, (ii) substitution of apparently mutilated, defaced, destroyed, lost or stolen Securities, (iii) rights of holders of Securities to receive payment of principal of and premium, if any, and interest on the Securities, (iv) rights, obligations and immunities of the Trustee under this Indenture (including, 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), and (v) rights of holders of the Securities as beneficiaries of this Indenture with respect to any property deposited with the Trustee payable to all or any of them, 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 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. -57- 69 ARTICLE FIVE Remedies SECTION 501. Events of Default. "Event of Default", wherever used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): (1) default in the payment of any interest upon any Security when it becomes due and payable, and continuance of such default for a period of 30 days;

or (6) a default or defaults under any bond(s), debenture(s), note(s) or other evidence(s) of Debt by the Company or any Significant Subsidiary of the Company or under any mortgage(s), indenture(s) or instrument(s) under which there may be issued or by which there may be secured or evidenced any Debt of such type by the Company or any such Significant Subsidiary with a principal amount then outstanding, individually or in the aggregate, in excess of $10 million, whether such Debt now exists or shall hereafter be created, which default or defaults shall constitute a failure to pay such Debt when due at the final maturity thereof, or shall have 70 resulted in such Debt becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable; or (7) a final judgment or final judgments (not subject to appeal) for the payment of money are entered against the Company or any Significant Subsidiary in an aggregate amount in excess of $10 million by a court or courts of competent jurisdiction, which judgments remain undischarged or unstayed for a period (during which execution shall not be effectively stayed) of 45 days after the right to appeal all such judgments has expired; or (8) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company or any Significant Subsidiary in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company or any Significant Subsidiary a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company or any Significant Subsidiary under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or any Significant Subsidiary or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; or (9) the commencement by the Company or any Significant Subsidiary of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company or any Significant Subsidiary in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or any Significant Subsidiary or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by -59- 71 the Company or any Significant Subsidiary in furtherance of any such action. SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default specified in Section 501(8) or (9) with respect to the Company) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities may declare the Default Amount of all the Securities 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 Default Amount and any accrued interest, together with all other amounts due under this Indenture, shall become immediately due and payable. If an Event of Default specified in Section 501(8) or (9) with respect to the Company occurs, the Default Amount of and any accrued interest on the Securities then Outstanding, together with all other amounts due under this Indenture, shall ipso facto become immediately due and payable without any declaration or other Act on the part of the Trustee or any Holder. The "Default Amount" in respect of any particular Security as of any particular date of acceleration on or before April 15, 2003 shall equal the Accreted Value of the Security on such date and as of any particular date of acceleration thereafter, shall equal the principal amount of the Security plus accrued and unpaid interest to such date. At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the money due based on acceleration has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate principal amount of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: (1) the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all overdue interest on all Securities, (B) the principal of (and premium, if any, on) any Securities which have become due otherwise than by such declaration of acceleration (including any Securities required to have been purchased on the Purchase Date pursuant to an Offer to Purchase 72 made by the Company) and interest thereon at the rate borne by the Securities, (C) to the extent that payment of such interest is lawful, interest upon overdue interest at the applicable rate borne by the 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, other than the non-payment of the principal of Securities 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. The Company covenants that if (1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or (2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof or, with respect to any Security required to have been purchased pursuant to an Offer to Purchase made by the Company, at the Purchase Date thereof, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium, if any) and 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 Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses incurred by the Trustee under this Indenture, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. -61- 73 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 Securities 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 Securities, 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 appropriate judicial proceedings as the Trustee shall deem most effective to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. SECTION 504. Trustee May File Proofs of Claim. In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys, securities or other property payable or deliverable upon the exchange of the Securities or upon any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. 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 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; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors or other similar committee. 74 SECTION 505. Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 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 principal (or premium, if any) or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: FIRST: To the payment of all amounts due the Trustee under Section 607; and SECOND: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest, respectively. The Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment to the Holders pursuant to this Section 506. SECTION 507. Limitation on Suits. No Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default; -63- 75 (2) the Holders of at least 25% in aggregate principal amount of the Outstanding Securities 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 and, if requested, provided 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 and, if requested, provision 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 60day period by the Holders of a majority in principal amount of the Outstanding Securities; 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 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 respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date or, in the case of an Offer to Purchase made by the Company and required to be accepted as to such Security, 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. 76 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 Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. SECTION 511. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security 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 of the Outstanding Securities 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 -65- 77 (1) such direction shall not be in conflict with any rule of law or with this Indenture or expose the Trustee to personal liability (as determined in the sole discretion of the Trustee), and (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. The Trustee may refuse, however, to follow any direction that the Trustee, in its sole discretion, determines may be unduly prejudicial to the rights of another Holder or that may subject the Trustee to any liability or expense if the Trustee determines, in its sole discretion, that it lacks indemnification against such loss or expense. SECTION 513. Waiver of Past Defaults. The Holders of not less than a majority in aggregate principal amount of the Outstanding Securities may on behalf of the Holders of all the Securities by written notice to the Trustee waive any past default hereunder and its consequences, except a default (1) in the payment of the principal of (or premium, if any) or interest on any Security (including any Security which is required to have been purchased pursuant to an Offer to Purchase 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 Security affected or (3) arising from failure to purchase any Security tendered pursuant to Sections 1013 and 1016. 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. 78 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 or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company. SECTION 515. Waiver of Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. ARTICLE SIX The Trustee SECTION 601. Certain Duties and Responsibilities. 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. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. -67- 79 SECTION 602. Notice of Defaults. The Trustee shall give the Holders notice of any Default hereunder as and to the extent provided by the Trust Indenture Act, unless such Default has been cured or waived; provided, however, that in the case of any Default of the character specified in Section 501(5), no such notice to Holders shall be given until at least 30 days after the occurrence thereof.

SECTION 604. Not Responsible for Recitals or Issuance of Securities. The recitals contained herein and in the Securities, 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 the Securities. The Trustee shall not be accountable for the use or application by the Company of Securities or the proceeds thereof. SECTION 605. May Hold Securities. The Trustee, any Paying Agent, any Security Registrar (if other than the Trustee) or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities 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, Security Registrar or such other agent. 81 SECTION 606.

In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. SECTION 613. Preferential Collection of Claims Against the Company.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company.

The foregoing restrictions shall not apply to: (i) Liens existing on the Issue Date and securing Debt outstanding on the Issue Date or securing the Securities or Liens securing Debt Incurred pursuant to any Bank Credit Agreement or Vendor Financing Facility (whether or not such Bank Credit Agreement or Vendor Financing Facility was outstanding on the Issue Date); (ii) Liens securing Debt in an amount which, together with the aggregate amount of Debt then outstanding or available under the Bank Credit Agreement and Vendor Financing Facility (or under refinancings or amendments of such agreements), does not exceed 1.5 times the Company's Consolidated Cash Flow Available for Fixed Charges for the four full fiscal quarters preceding the Incurrence of such Lien for which consolidated financial statements are available, determined on a pro forma basis as if such Debt had been Incurred and the proceeds thereof had been applied at the beginning of such four fiscal quarters; (iii) Liens in favor of the Company or any Wholly-Owned Restricted Subsidiary of the Company; (iv) Liens on real or personal property of the Company or a Restricted Subsidiary of the Company acquired, constructed or constituting improvements made after the Issue Date to secure Purchase Money Debt which is Incurred for the construction, acquisition and improvement of Telecommunications Assets and is otherwise permitted under this Indenture, provided, however, that (a) the net proceeds of any Debt secured by such a Lien does not exceed 100% of such purchase price or cost of construction or improvement of the property subject to such Lien, (b) such Lien attaches to such property prior to, at the time of or within 180 days after the acquisition, completion of construction or commencement of operation of such property and (c) such Lien does not extend to or cover any property other than the property (or identifiable portions thereof) acquired, constructed or constituting the improvements made with the proceeds of such Purchase Money Debt (it being understood and agreed that all Debt owed to any single lender or group of lenders or outstanding under any single credit facility shall be considered a 112 single Purchase Money Debt, whether drawn at one time or from time to time); (v) Liens to secure Acquired Debt, provided, however, that (a) such Lien attaches to the acquired asset prior to the time of the acquisition of such asset and (b) such Lien does not extend to or cover any other asset; (vi) Liens to secure Debt Incurred to extend, renew, refinance or refund (or successive extensions, renewals, refinancings or refundings), in whole or in part, Debt secured by any Lien referred to in the foregoing clauses (i), (ii), (iv) and (v) so long as such Lien does not extend to any other property and the principal amount of Debt so secured is not increased except as otherwise permitted under clause (iv) of Section 1007; (vii) Liens securing Debt not otherwise permitted by the foregoing clauses (i) through (vi) in an amount not to exceed 5% of the Company's Consolidated Tangible Assets determined as of the most recent available quarterly or annual balance sheet; and (viii) Permitted Liens.

For any transaction that involves in excess of $1 million but less than or equal to $15 million, the Chief Executive Officer of the Company shall determine that the transaction satisfies the above criteria and shall evidence such a determination by an Officer's Certificate filed with the Trustee. For any transaction that involves in excess of $15 million, the Company shall also obtain an opinion from a nationally recognized expert with experience in appraising the terms and conditions, taken as a whole, of the type of transaction (or series of related transactions) for which the opinion is required stating that such transaction (or series of related transactions) is on terms and conditions, taken as a whole, no less favorable to the Company or such Restricted Subsidiary than those that could be obtained in a comparable arm's-length transaction with an entity that is not an Affiliate or Related Person of the Company, which opinion shall be filed with the Trustee. This covenant shall not apply to Investments by an Affiliate or a Related Person of the Company in the Capital Stock (other than Disqualified Stock) of the Company or any Restricted Subsidiary of the Company. SECTION 1016. Change of Control. (a) Within 30 days of the occurrence of a Change of Control, the Company will be required to make an Offer to Purchase all Outstanding Securities at a purchase price equal to 101% of their Accreted Value (if such Offer to Purchase is made on or prior to April 15, 2003) or 101% of their principal amount plus accrued and unpaid interest to the date of purchase (if such Offer to Purchase is consummated thereafter). (b) The Company and Trustee shall perform their respective obligations specified in the Offer for the Offer to Purchase. On or prior to the Purchase Date, the Company shall (i) accept for payment Securities or portions thereof tendered pursuant to the Offer, (ii) deposit with the Paying Agent (or, if -105- 117 the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) money sufficient to pay the purchase price of all Securities or portions thereof so accepted and (iii) deliver or cause to be delivered to the Trustee all Securities so accepted together with an Officers' Certificate stating the Securities or portions thereof accepted for payment by the Company. The Paying Agent shall promptly mail or deliver to Holders of Securities so accepted payment in an amount equal to the purchase price, and the Trustee shall promptly authenticate and mail or deliver to such Holders a new Security or Securities equal in principal amount to any unpurchased portion of the Security surrendered as requested by the Holder. Any Security not accepted for payment shall be promptly mailed or delivered by the Company to the Holder thereof. (c) A "Change of Control" will be deemed to have occurred at such time as either (a) any Person or any Persons acting together that would constitute a "group" (a "Group") for purposes of Section 13(d) of the Exchange Act, or any successor provision thereto (other than Eagle River, Mr. Craig O. McCaw and their respective Affiliates or an underwriter engaged in a firm commitment underwriting on behalf of the Company), shall beneficially own (within the meaning of Rule 13d-3 under the Exchange Act, or any successor provision thereto) more than 50% of the aggregate voting power of all classes of Voting Stock of the Company; or (b) neither Mr. Craig O. McCaw nor any person designated by him to the Company as acting on his behalf shall be a director of the Company; or (c) during any period of two consecutive years, individuals who at the beginning of such period constituted the Board of Directors (together with any new directors whose election by the Board of Directors or whose nomination for election by the shareholders of the Company was proposed by a vote of a majority of the directors of the Company then still in office who were either directors at the beginning of such period or whose election or nomination for election was previously so approved) cease for any reason to constitute a majority of the Board of Directors then in office. (d) In the event that the Company makes an Offer to Purchase the Securities, the Company intends to comply with any applicable securities laws and regulations, including any applicable requirements of Section 14(e) of, and Rule 14e-1 under, the Exchange Act. (e) Unless the Company defaults in the payment of the Purchase Price, any Security accepted for payment pursuant to an Offer to Purchase shall cease to accrue interest after the Purchase Date. 118 SECTION 1017. Provision of Financial Information. The Company has agreed to file with the Trustee, within 15 days after it files them with the Commission, copies of the SEC Reports. In the event the Company shall cease to be required to file SEC Reports pursuant to the Exchange Act, the Company will nevertheless continue to file such reports with the Commission (unless the Commission will not accept such a filing) and the Trustee. The Company will furnish copies of the SEC Reports to the Holders of Securities at the time the Company is required to file the same with the Trustee and will make such information available to investors who request it in writing. SECTION 1018. Statement by Officers as to Default. (a) The Company will deliver to the Trustee, within 90 days after the end of each quarter of each fiscal year of the Company ending after the date hereof, an Officers' Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture and if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. (b) The Company shall deliver to the Trustee, as soon as possible and in any event within 10 days after the Company becomes 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. SECTION 1019. Waiver of Certain Covenants. The Company may omit in any particular instance to comply with any covenant or condition set forth in Sections 1004 to 1017, inclusive, if before or after the time for such compliance the Holders of at least a majority in aggregate principal amount of the Outstanding Securities shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect. -107- 119 ARTICLE ELEVEN Redemption of Securities SECTION 1101. Right of Redemption. (a) The Securities may be redeemed prior to April 15, 2003 only in the event that on or before April 15, 2001 the Company receives net proceeds from a sale of its Common Equity, in which case the Company may, at its option, use all or a portion of any such net proceeds to redeem Securities in a principal amount of up to an aggregate amount equal to 33 % of the original principal amount of the Securities provided, however, that Securities in an amount equal to at least 66 % of the original aggregate principal amount of the Notes remain outstanding after such redemption. Such redemption must occur on a Redemption Date within 90 days of any such sale and upon not less than 30 nor more than 60 days' notice by mail to each Holder of Securities to be redeemed at such Holder's address appearing in the Security Register, in amounts of $1,000 or an integral multiple of $1,000 at a Redemption Price of 109.450% of the Accreted Value of the Securities to but excluding the Redemption Date. (b) The Securities further may be redeemed, as a whole or in part, at the election of the Company, at any time on or after April 15, 2003 and prior to maturity, upon not less than 30 nor more than 60 days' notice by mail to each Holder of Securities to be redeemed at such Holder's address appearing in the Security Register, in amounts of $1,000 or an integral multiple of $1,000, at the Redemption Prices specified in the form of Security hereinbefore set forth, together with accrued and unpaid interest to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date). SECTION 1102. Applicability of Article. Redemption of Securities at the election of the Company, as permitted or required by any provision of this Indenture, shall be made in accordance with such provision and this Article. 120 SECTION 1103. Election to Redeem; Notice to Trustee. The election of the Company to redeem any Securities pursuant to Section 1101 shall be evidenced by Board Resolution. In case of any redemption at the election of the Company of less than all the Securities, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal amount of Securities to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers' Certificate evidencing compliance with such restriction. SECTION 1104. Securities to Be Redeemed Pro Rata. If less than all the Securities are to be redeemed in any redemption, the Securities to be redeemed shall be selected by the Trustee by prorating, as nearly as may be practicable, the principal amount of Securities to be redeemed. In any proration pursuant to this Section, the Trustee shall make such adjustments, reallocations and eliminations as it shall deem proper (and in compliance with the requirements of the principal national securities exchange, if any, on which the Securities are listed) to the end that the principal amount of Securities so prorated shall be $1,000 or a multiple thereof, by increasing or decreasing or eliminating the amount which would be allocable to any Holder on the basis of exact proportion by an amount not exceeding $1,000. The Trustee in its discretion may determine the particular Securities (if there are more than one) registered in the name of any Holder which are to be redeemed, in whole or in part. The Trustee shall promptly notify the Company and each Security Registrar (other than the Trustee) in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. -109- 121 SECTION 1105. Notice of Redemption. Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at such Holder's address appearing in the Security Register. All notices of redemption shall state: (1) the Redemption Date, (2) the Redemption Price, (3) whether the redemption is being made pursuant to Section 1101(a) or (b) and, if being made pursuant to Section 1101(a), a brief statement setting forth the Company's right to effect such redemption and the Company's basis therefor, (4) if less than all the Outstanding Securities are to be redeemed, the identification (and, in the case of partial redemption of any Securities, the principal amounts) of the particular Securities to be redeemed, (5) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and that interest thereon will cease to accrue on and after said date, (6) the place or places where such Securities are to be surrendered for payment of the Redemption Price, (7) that in the case that a Security is only redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities in an aggregate amount equal to the unredeemed portion of the Security, (8) the aggregate principal amount of Securities being redeemed, and (9) the CUSIP number or numbers of the Securities being redeemed. Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, if request is made to the Trustee no less than 35 days prior to the Redemption Date, by the Trustee in the name and at the expense of the Company. 122 SECTION 1106. Deposit of Redemption Price. Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued and unpaid interest on, all the Securities which are to be redeemed on that date. SECTION 1107. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued and unpaid interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued and unpaid interest to the Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate provided by the Security. -111- 123 SECTION 1108. Securities Redeemed in Part. Any Security which is to be redeemed only in part shall be surrendered at an office or agency of the Company designated for that purpose pursuant to Section 1002 (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. If a Global Security is so surrendered, such new Security shall also be a Global Security. ARTICLE TWELVE Defeasance and Covenant Defeasance SECTION 1201. Company's Option to Effect Defeasance or Covenant Defeasance. The Company may, at its option by Board Resolution at any time (subject to 10-day prior written notification to the Trustee), elect to have either Section 1202 or Section 1203 applied to the Outstanding Securities upon compliance with the conditions set forth below in this Article Twelve. 124 SECTION 1202. Defeasance and Discharge. Upon the Company's exercise of the option provided in Section 1201 applicable to this Section, the Company shall be deemed to have been discharged from its obligations with respect to the Outstanding Securities on the date the conditions set forth below are satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Securities and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (A) the rights of Holders of Outstanding Securities to receive, solely from the trust fund described in Section 1204 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any) and interest on such Securities when such payments are due, (B) the Company's obligations with respect to such Securities under Sections 304, 305, 306, 1002 and 1003, (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (D) this Article Twelve. Subject to compliance with this Article Twelve, the Company may exercise its option under this Section 1202 notwithstanding the prior exercise of its option under Section 1203. SECTION 1203. Covenant Defeasance. Upon the Company's exercise of the option provided in Section 1201 applicable to this Section (i) the Company shall be released from its obligations under Sections 1005 through 1017, inclusive, and Clauses (3) and (4) of Section 801, (ii) the occurrence of an event specified in Sections 501(3), 501(4) (with respect to Clauses (3) and (4) of Section 801), and 501 (5) (with respect to Sections 1005 through 1017, inclusive) shall not be deemed to be an Event of Default, on and after the date the conditions set forth below are satisfied (hereinafter, "covenant defeasance"). For this purpose, such covenant defeasance means that the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section or Article, whether directly or indirectly by reason of any reference elsewhere herein to any such Section or Article or by reason of any reference in any such Section or Article to any other provision herein or in any other document, but the remainder of this Indenture and such Securities shall be unaffected thereby. -113- 125 SECTION 1204. Conditions to Defeasance or Covenant Defeasance. The following shall be the conditions to application of either Section 1202 or Section 1203 to the Outstanding Securities: (1) The Company shall irrevocably have deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent certified public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee to pay and discharge, the principal of, premium, if any, and each installment of interest on the Securities on the Stated Maturity of such principal or installment of interest on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities. For this purpose, "U.S. Government Obligations" means securities that are (x) direct obligations of the United States of America for the payment of which its full faith and credit is pledged or (y) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case, are not callable or redeemable at the option of the issuer thereof, and shall also include a depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any such U.S. Government Obligation or a specific payment of principal of or interest on any such U.S. Government Obligation held by such custodian for the account of the holder of such depositary receipt, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal of or interest on the U.S. Government Obligation evidenced by such depositary receipt. (2) No Default or Event of Default shall have occurred and be continuing on the date of such deposit or, insofar as subsections 501(8) and (9) are concerned, at any time during the period ending on the 91st 126 day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period). (3) Such defeasance or covenant defeasance shall not cause the Trustee to have a conflicting interest as defined in Section 608 and for purposes of the Trust Indenture Act with respect to any securities of the Company. (4) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other agreement or instrument to which the Company is a party or by which it is bound. (5) The Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the defeasance under Section 1202 or the covenant defeasance under Section 1203 (as the case may be) have been complied with. (6) In the case of an election under Section 1202, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (x) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (y) since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the Outstanding Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not occurred. (7) In the case of an election under Section 1203, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the Outstanding Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred. (8) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect that such deposit and defeasance or covenant defeasance shall not result in the trust arising from such deposit constituting an investment company as defined in the Investment Company Act of -115- 127 1940, as amended, or such trust shall be qualified under such act or exempt from regulation thereunder. SECTION 1205. Deposited Money and U.S. Government Obligations to Be Held in Trust; Other Miscellaneous Provisions. Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee--collectively, for purposes of this Section 1205, the "Trustee") pursuant to Section 1204 in respect of the Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such 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 Holders of such Securities, of all sums due and to become due thereon in respect of principal (and premium, if any) and interest, but such money need not be segregated from other funds except to the extent required by law. The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 1204 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Securities. Anything in this Article Twelve to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 1204 which, in the opinion of a nationally recognized accounting firm expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent defeasance or covenant defeasance. 128 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, then the Company's obligations under this Indenture and the Securities 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 and 1203; provided, however, that if the Company makes any payment of principal of (and premium, if any) any Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or the Paying Agent. SECTION 1207. Repayment to Company. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Security and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and payable shall be paid to the Company on its written request or (if then held by the Company) shall be discharged from such trust; and the Holder of such security shall thereafter, as a creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. 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. -117- 129 IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed and attested, and the Trustee has caused its seal to be hereunto affixed and attested, all as of the day and year first above written.
