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

(e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Note. SECTION 105.

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. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice. Where this Indenture provides for 32 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 or irregularities in regular mail service or by reason of any other cause, it shall be impracticable to mail notice of any event to Holders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice for every purpose hereunder.

In case the Company, pursuant to Article Eight, shall be consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise dispose of its properties and assets substantially as an entirety to any Person, and the successor Person resulting from such consolidation, or surviving such merger, or into which the Company shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid, shall have executed an indenture supplemental hereto with the Trustee pursuant to Article Eight, any of the Notes authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may, from time to time, at the request of the successor Person, be exchanged for other Notes executed in the name of the successor Person with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Notes surrendered for such exchange and of like principal amount; and the Trustee, upon Company Request of the successor Person, shall authenticate and deliver Notes as specified in such request for the purpose of such exchange. If Notes shall at any time be authenticated and delivered in any new name of a successor Person pursuant to this Section 303 in exchange or substitution for 46 or upon registration of transfer of any Notes, such successor Person, at the option of the Holders but without expense to them, shall provide for the exchange of all Notes at the time Outstanding for Notes authenticated and delivered in such new name.

If temporary Notes are issued, the Company will cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Company designated for such purpose pursuant to Section 1002, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Company shall execute, and the Trustee shall authenticate and deliver in exchange therefor, a like principal amount of definitive Notes of authorized denominations. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as definitive Notes. 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 referred to as the "Note Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. The Note Register shall be in written form or any other form capable of being converted into written form within a reasonable time. At all reasonable times, the Note Register shall be open to inspection by the Trustee. The Trustee is hereby initially appointed as security registrar (the "Note Registrar") for the purpose of registering Notes and transfers of Notes as herein provided. Upon surrender for registration of transfer of any Note at the office or agency of the Company designated pursuant to Section 1002, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations of a like aggregate principal amount. 47 At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is entitled to receive; provided that no exchange of Initial Notes for Exchange Notes shall occur until an Exchange Offer Registration Statement shall have been declared effective by the Commission, the Trustee shall have received an Officer's Certificate confirming that the Exchange Offer Registration Statement has been declared effective by the Commission and the Initial Notes to be exchanged for the Exchange Notes shall be cancelled by the Trustee. All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Note Registrar) be duly endorsed, or be accompanied by a written instrument of transfer, in form satisfactory to the Company and the Note Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange or redemption of Notes, 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 Notes, other than exchanges pursuant to Section 304, 906, 1010, 1017 or 1108 not involving any transfer. The Company shall not be required (i) to issue, register the transfer of or exchange any Note during a period beginning at the opening of business 15 days before the selection of Notes to be redeemed under Section 1104 and ending at the close of business on the day of such mailing of the relevant notice of redemption, or (ii) to register the transfer of or exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. SECTION 306. Mutilated, Destroyed, Lost and Stolen Notes. If (i) any mutilated Note is surrendered to the Trustee, or (ii) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Company and the Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a bona fide purchaser, the Company shall execute and upon Company Order the Trustee shall authenticate and deliver, 48 in exchange for any such mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously outstanding. In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note. Upon the issuance of any new Note 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 Note issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes 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 Notes. SECTION 307. Payment of Interest; Interest Rights Preserved. Interest on any Note 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 such Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose pursuant to Section 1002; provided, however, that each installment of interest may at the Company's option be paid by (i) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 308, to the address of such Person as it appears in the Note Register or (ii) transfer to an account located in the United States maintained by the payee. Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the Holder on the Regular Record Date by virtue of having been such Holder, and such defaulted interest and (to the extent lawful) interest on such defaulted interest at the rate borne by the Notes (such defaulted interest and interest thereon herein collectively called "Defaulted Interest") may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below: 49 (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor Notes) 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 Note 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 given in the manner provided for in Section 106, 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 given, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) 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 Notes 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 Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note. SECTION 308. Persons Deemed Owners. Prior to the due presentment of a Note 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 Note is registered as the owner of such Note for the purpose of receiving payment of principal of (and premium and Liquidated Damages, if any) and (subject to Sections 305 and 307) interest on such Note and for all other purposes whatsoever, whether or 50 not such Note 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 Notes surrendered for payment, redemption, registration of transfer or exchange 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 Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Notes previously authenticated hereunder which the Company has not issued and sold, and all Notes so delivered shall be promptly cancelled by the Trustee. If the Company shall so acquire any of the Notes, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Notes held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures and certification of their disposal delivered to the Company unless by Company Order the Company shall direct that cancelled Notes be returned to it. SECTION 310. Computation of Interest. Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. SECTION 311. Book-Entry Provisions for Global Notes. (a) Each Global Note initially shall (i) be registered in the name of the Depositary for such Global Notes or the nominee of such Depositary, (ii) be delivered to the Trustee as custodian for such Depositary and (iii) bear legends as set forth in Section 203. Except as provided in Section 311(b), owners of beneficial interests in the Global Notes will not have Notes registered in their names, will not receive physical delivery of Notes in certificated form and will not be considered the registered owner or Holder thereof under this Indenture for any purpose. Members of, or Participants in, the Depositary shall have no rights under this Indenture with respect to any Global Note, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent 51 the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Participants, the operation of customary practices governing the exercise of the rights of a beneficial owner of any Note. The registered Holder of a Global Note may grant proxies and otherwise authorize any person, including Participants and persons that may hold interests through Participants, to take any action which a Holder is entitled to take under this Indenture or the Notes. (b) Interests of beneficial owners in a Global Note may be transferred in accordance with the applicable rules and procedures of the Depositary and the provisions of Section 312. Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to the Depositary, a nominee of the Depositary, its successors or their respective nominees, except (i) as otherwise set forth in Section 312 and (ii) U.S. Physical Notes or Offshore Physical Notes shall be transferred to beneficial owners in exchange for their beneficial interests in the U.S. Global Note or the Offshore Global Note, as the case may be, if the Depositary (1) notifies the Company that it is unwilling or unable to continue as depository for the applicable Global Note and the Company thereupon fails to appoint a successor depository or (2) has ceased to be a clearing agency registered under the Exchange Act. In connection with a transfer of an entire Global Note to beneficial owners pursuant to clause (ii) of this paragraph (b), the applicable Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in the applicable Global Note, an equal aggregate principal amount of U.S. Physical Notes (in the case of the U.S. Global Note) or Offshore Physical Notes (in the case of the Offshore Global Note), as the case may be, of authorized denominations. (c) Any beneficial interest in one of the Global Notes that is transferred to a Person who takes delivery in the form of an interest in the other Global Note will, upon transfer, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest. (d) Any U.S. Physical Note delivered in exchange for an interest in the U.S. Global Note pursuant to paragraph (b) of this Section shall, unless such exchange is made on or after (i) an Initial Note is sold pursuant to an effective Shelf Registration Statement, pursuant to the Notes Registration Rights Agreement, (ii) an Initial Note is exchanged for an Exchange Note in an Exchange Offer pursuant to an effective Exchange Offer Registration Statement, pursuant to the Notes Registration Rights Agreement, or (iii) two years after the later of the Issue Date and the last date on which the Company or any affiliate of the Company was the owner of the Initial Note (the "Resale Restriction Termination Date") evidenced by an opinion of counsel to such Holder reasonably satisfactory to the Company and except as otherwise provided in Section 312, bear the Private Placement Legend. 52 SECTION 312. Transfer Provisions. Unless and until (i) an Initial Note is sold pursuant to an effective Registration Statement, or (ii) an Initial Note is exchanged for an Exchange Note in connection with an effective Registration Statement pursuant to the Notes Registration Rights Agreement, the following provisions shall apply: (a) General. The provisions of this Section 312 shall apply to all transfers involving any Physical Note and any beneficial interest in any Global Note. (b) Certain Definitions. As used in this Section 312 only, "delivery" of a certificate by a transferee or transferor means the delivery to the Note Registrar by such transferee or transferor of the applicable certificate duly completed; "holding" includes both possession of a Physical Note and ownership of a beneficial interest in a Global Note, as the context requires; "transferring" a Global Note means transferring that portion of the principal amount of the transferor's beneficial interest therein that the transferor has notified the Note Registrar that it has agreed to transfer; and "transferring" a Physical Note means transferring that portion of the principal amount thereof that the transferor has notified the Note Registrar that it has agreed to transfer.

SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default specified in Section 501(6) or 501(7)) 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 Notes then Outstanding by written notice to the Company (and to the Trustee, if such notice is given by the Holders) may, and the Trustee upon the written request of such Holders shall, declare the principal amount, premium if any and accrued and unpaid interest and Liquidated Damages, if any, on all of the Outstanding Notes to be due and payable immediately, and upon any such declaration all such amounts payable in respect of the Notes shall become immediately due and payable. If an Event of Default specified in Section 501(6) or 501(7) occurs and is continuing, then the principal of, premium, if any, accrued interest and Liquidated Damages, if any, on all of the Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. At any time after a declaration of acceleration has been made but before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article, the holders of a majority in aggregate principal amount of the Outstanding Notes, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if (a) the Company has paid or deposited with the Trustee a sum sufficient to pay, (i) all overdue interest on all Outstanding Notes, (ii) all unpaid principal of (and premium, if any, on) any Outstanding Notes that have become due otherwise than by such declaration of acceleration, together with interest on such unpaid principal at the rate borne by the Notes, (iii) to the extent that payment of such interest is lawful, interest upon overdue interest and Liquidated Damages, if any, and overdue principal at the rate borne by the Notes, and 64 (iv) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and (b) all Events of Default, other than the non-payment of amounts of principal of (or premium, if any, on) or interest and Liquidated Damages, if any, on the Notes that 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. Notwithstanding the preceding paragraph, in the event of a declaration of acceleration in respect of the Notes because of an Event of Default specified in Section 501(4) shall have occurred and be continuing, such declaration of acceleration shall be automatically annulled if the Indebtedness that is the subject of such Event of Default has been discharged or the holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness, and written notice of such discharge or rescission, as the case may be, shall have been given to the Trustee by the Company and countersigned by the holders of such Indebtedness or a trustee, fiduciary or agent for such holders, within 30 days after such declaration of acceleration in respect of the Notes, and no other Event of Default has occurred during such 30-day period which has not been cured or waived during such period. SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if (a) default is made in the payment of any installment of interest and Liquidated Damages, if any, on any Note when such interest becomes due and payable and such default continues for a period of 30 days, or (b) default is made in the payment of the principal of (or premium, if any, on) any Note at the Maturity thereof, the Company will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal (and premium and Liquidated Damages, if any) and interest, and interest on any overdue principal (and premium, if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installment of interest and Liquidated Damages, if any, at the rate borne by the Notes, 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. 65 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name 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 Notes 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 Notes, 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 effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. SECTION 504. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Notes or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium, if any, or interest or Liquidated Damages, if any) shall be entitled and empowered, by intervention in such proceeding or otherwise, (i) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and (ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or 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 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 606. 66 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 505. Trustee May Enforce Claims Without Possession of Notes. All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and 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 Notes 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 or Liquidated Damages, if any) or interest, upon presentation of the Notes 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 to the Trustee under Section 606; second: To the payment of the amounts then due and unpaid for principal of (and premium and Liquidated Damages, if any) and interest on the Notes 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 Notes for principal (and premium and Liquidated Damages, if any) and interest, respectively; third: To the payment of any and all amounts due to the Person or Persons entitled thereto; and fourth: The balance, if any, to the Company. SECTION 507. Limitation on Suits. No Holder of any Notes 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 67 (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 aggregate principal amount of the Outstanding Notes 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 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 or more in principal amount of the Outstanding Notes; 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 Note shall have the right, which is absolute and unconditional, to receive payment, as provided herein (including, if applicable, Article Thirteen) and in such Note of the principal of (and premium and Liquidated Damages, if any) and (subject to Section 307) interest on such Note on the respective Stated Maturities expressed in such Note (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. SECTION 509. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions 68 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 Notes 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 Note 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 not less than a majority in principal amount of the Outstanding Notes 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, (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and (3) the Trustee need not take any action which might involve it in personal liability or be unjustly prejudicial to the Holders not consenting. 69 SECTION 513. Waiver of Past Defaults. The Holders of not less than a majority in aggregate principal amount of the Outstanding Notes may on behalf of the Holders of all the Notes waive any past default hereunder and its consequences, except a default (1) in the payment of the principal of (or premium and Liquidated Damages, if any) or interest on any Note, 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 Note. Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. SECTION 514. 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. Notice of Defaults.

In case any Notes 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 Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes. In case at that time any of the Notes shall not have been authenticated, any successor Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates shall have the full force and effect which this Indenture provides for the certificate of authentication of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

The Corporate Trust Office of the Trustee shall be such office or agency of the Company, unless the Company shall designate and maintain some other office or agency for one or more of such purposes. The Company will give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Administration office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. The Company may also from time to time designate one or more other offices or agencies (in or outside of The City of New York) where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind any such designation; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in The City of New York for such purposes. The Company will give prompt written notice to the Trustee of 83 any such designation or rescission and any change in the location of any such other office or agency. SECTION 1003. Money for Note Payments to Be Held in Trust. If the Company shall at any time act as its own Paying Agent, it will, on or before each due date of the principal of (or premium and Liquidated Damages, if any) or interest on any of the Notes, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal of (or premium and Liquidated Damages, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. Whenever the Company shall have one or more Paying Agents for the Notes, it will, on or before 10:00 a.m. on each due date of the principal of (or premium and Liquidated Damages, if any) or interest on any Notes, deposit with a Paying Agent a sum sufficient to pay the principal (and premium and Liquidated Damages, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of such action or any failure so to act. The Company shall cause each Paying Agent (other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: (1) hold all sums held by it for the payment of the principal of (and premium and Liquidated Damages, if any) or interest on Notes in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; (2) give the Trustee notice of any default by the Company (or any other obligor upon the Notes) in the making of any payment of principal (and premium and Liquidated Damages, if any) or interest; and (3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any 84 Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums. 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 (or premium and Liquidated Damages, if any) or interest on any Note and remaining unclaimed for two years after such principal, premium, interest or Liquidated Damages has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust. The Holder of such Note, as an unsecured general creditor, shall look thereafter only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in the Borough of Manhattan, The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

SECTION 1005. Payment of Taxes and Other Claims. The Company shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all material taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Restricted Subsidiary and (b) all material lawful claims for labor, materials and supplies, which, if unpaid, might by law become a lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings. 85 SECTION 1006. Maintenance of Properties. The Company shall, or shall cause its Restricted Subsidiaries to, cause all material properties owned by the Company or any Restricted Subsidiary or used or held for use in the conduct of its business or the business of any Restricted Subsidiary to be maintained and kept in good condition, repair and working order (reasonable wear and tear excepted) and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section 1006 shall prevent the Company or a Restricted Subsidiary from discontinuing the maintenance of any of such properties or disposing of them as otherwise permitted herein if such discontinuance or disposition is, in the judgment of the Company, desirable in the conduct of its business or the business of the Company or such Restricted Subsidiary and not disadvantageous in any material respect to the Holders. SECTION 1007. Insurance. The Company shall at all times keep all of its and its Restricted Subsidiaries properties which are of an insurable nature insured with insurers, believed by the Company to be responsible, against loss or damage to the extent that property of similar character is usually so insured by corporations similarly situated and owning like properties.

(a) The Company shall deliver to the Trustee, within 50 days after the end of each fiscal quarter and within 120 days after the end of each fiscal year, a brief certificate from the principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of the Company's compliance with all conditions and covenants under this Indenture since beginning of such quarter or year, as the case may be. For purposes of this Section 1008(a), such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture. (b) When any Default has occurred and is continuing under this Indenture, or if the trustee for or the holder of any other evidence of Indebtedness of the Company or any Subsidiary gives any notice or takes any other action with respect to a claimed default (other than with respect to Indebtedness in the principal amount of less than $7,500,000), the Company shall deliver to the Trustee by registered or certified mail or by facsimile transmission an Officers' Certificate specifying such event, notice or other action within five Business Days of an officer of the Company becoming aware of its occurrence.

(a) The Company shall file on a timely basis with the Commission, to the extent such filings are accepted by the Commission and whether or not the Company has a class of securities registered under the Exchange Act, the annual reports, quarterly reports and other documents that the Company would be required to file if it were subject to Section 13 or 15(d) of the Exchange Act. (b) The Company shall also be required (i) to file with the Trustee, and provide to each Holder of Notes, without cost to such Holder, copies of such reports and documents within 15 days after the date on which the Company files such reports and documents with the Commission or the date on which the Company would be required to file such reports and documents if the Company were so required, and (ii) if filing such reports and documents with the Commission is not accepted by the Commission or is prohibited under the Exchange Act, to supply at the Company's cost copies of such reports and documents to any prospective holder promptly upon request. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers' Certificates). SECTION 1010. Purchase of Notes upon Change of Control. (a) Upon the occurrence of a Change of Control at any time and subject to the compliance by the Company with the requirements of paragraph (b) of this Section 1010, each Holder shall have the right to require that the Company repurchase all of such Holder's Notes, in whole or in part in integral multiples of $1,000, at a purchase price (the "Change of Control Purchase Price") in cash in an amount equal to 101% of the principal amount thereof, plus accrued and unpaid interest and Liquidated Damages, if any, thereon to the date of purchase, in accordance with the procedures set forth in paragraphs (b) and (c) of this Section 1010 (the "Change of Control Offer").

The Company shall not, and shall not permit any Restricted Subsidiary to, enter into or suffer to exist, directly or indirectly, any transaction or series of related transactions (including, without limitation, the sale, purchase, exchange or lease of assets, property or services) with, or for the benefit of, any Affiliate of the Company or any Restricted Subsidiary (other than the Company or a Restricted Subsidiary so long as no Affiliate of the Company (other than a Restricted Subsidiary) shall beneficially own Capital Stock in such Restricted Subsidiary) unless (i) such transaction or series of related transactions are on terms, taken as a whole, that are no less favorable to the Company or such Restricted Subsidiary, as the case may be, than those that could have been obtained in an arm's length transaction with unrelated third parties that are not Affiliates; (ii) with respect to any transaction or series of related transactions involving aggregate consideration equal to or greater than $5,000,000, the Company will deliver an Officers' Certificate to the Trustee certifying that such transaction or series of related transactions complies with clause (i) above; and (iii) with respect to any transaction or series of related transactions involving aggregate consideration in excess of $10,000,000, the Company will deliver the Officers' Certificate described in clause (ii) above which will also certify that such transaction or series of related transactions has been approved by a majority of the Disinterested Directors of the Board of Directors of the Company or that the Company has obtained a written opinion from an independent financial expert, certifying that the financial terms of such transaction or series of related transactions, taken as a whole, are fair to the Company or such Restricted Subsidiary, as the case may be, from a financial point of view; provided, however, that this covenant shall not restrict (1) any transaction or series of related transactions among the Company and one or more of its Restricted Subsidiaries or among its Restricted Subsidiaries, (2) the Company from paying reasonable and customary regular compensation and fees to directors of the Company or any Restricted Subsidiary who are not employees of the Company or any Restricted Subsidiary, (3) the performance of the Company's obligations under the Investment and Stockholders' Agreement, dated as of October 31, 1997, among the Company, David Schaeffer and the Investors named therein, as amended; the Investment and Stockholders' Agreement, dated as of August 28, 1995, by and among the Company and the Investors named therein; the Investment and Stockholders' Agreement, dated as of December 23, 1996, by and among the Company and the Investors named therein; the Non-Qualified Stock Option Agreement, dated August 4, 1997, between the Company and Richard Jalkut; and the Employment Agreement, dated August 4, 1997, between the Company and Richard Jalkut, in each case as amended through the Issue Date; provided that any amendments or modifications to the terms of transactions described in this clause (3) will be (x) no less favorable to the Company than those that could have been obtained in an arm's length transaction with unrelated third parties who are not Affiliates and (y) approved by the Board of Directors of the Company (including 93 a majority of the Disinterested Directors), (4) the making of any Restricted Payment not prohibited by Section 1012 and (5) loans or advances made to directors, officers or employees of the Company or any Restricted Subsidiary, or guarantees in respect thereof or otherwise made on their behalf, in respect of expenses incurred in the ordinary course of business, in an aggregate principal amount not to exceed $500,000 in any calendar year. SECTION 1015. Limitations on Liens. The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume or suffer to exist any Lien (other than Permitted Liens) on or with respect to any of its property or assets (including, without limitation, any shares of Capital Stock or Indebtedness of any Restricted Subsidiary) whether owned at the Issue Date or thereafter acquired, or any income, profits or proceeds therefrom, or assign or otherwise convey any right to receive income thereon, unless (x) in the case of any Lien securing Indebtedness of the Company that is expressly subordinated in right of payment to the Notes, the Notes are secured by a Lien on such property, assets or proceeds that is senior in priority to such Lien and (y) in the case of any other Lien, the Notes are secured by a Lien on such property, assets or proceeds that is senior in priority to, or equally and ratably secured with, the obligation or liability secured by such Lien. SECTION 1016. Limitation on Issuances of Certain Guarantees by, and Debt Securities of, Restricted Subsidiaries. The Company shall not permit any Restricted Subsidiary to (i) directly or indirectly guarantee, assume or in any other manner become liable with respect to any Debt Securities ("Guaranteed Indebtedness") or (ii) issue any Debt Securities, unless, in either such case, such Restricted Subsidiary simultaneously executes and delivers a supplemental indenture providing for the guarantee (a "Subsidiary Guarantee") of payment of the Notes. If the Guaranteed Indebtedness (A) ranks equally in right of payment with the Notes, then the guarantee of such Guaranteed Indebtedness will rank equally in right of payment with, or be subordinated in right of payment to, the Subsidiary Guarantee or (B) is subordinated in right of payment to the Notes, then the guarantee of such Guaranteed Indebtedness will be subordinated in right of payment to the Subsidiary Guarantee at least to the extent that the Guaranteed Indebtedness is subordinated in right of payment to the Notes. The obligations of each Restricted Subsidiary under a Subsidiary Guarantee will be limited to the maximum amount, as will, after giving effect to all other contingent and fixed liabilities of such Restricted Subsidiary, result in the obligations of such Restricted Subsidiary under the Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law. Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted Subsidiary of the Notes shall provide by its terms that it shall be automatically and unconditionally released and discharged upon (i) the sale or other disposition, by way of 94 merger or otherwise, to any Person not an Affiliate of the Company, of all of the Company's and its Restricted Subsidiaries' Capital Stock in such Restricted Subsidiary, (ii) the merger or consolidation of the applicable Restricted Subsidiary with and into the Company or another Restricted Subsidiary that has guaranteed the Notes and that is the surviving Person in such merger or consolidation and (iii) the release by all of the holders of Debt Securities of the Company of such Restricted Subsidiary's obligations under all of its Guarantees in respect thereof and the release by all of the holders of Debt Securities of such Restricted Subsidiary of its obligations thereunder. SECTION 1017. Limitation on Sale of Assets. (a) The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, engage in any Asset Sale unless (i) the consideration received by the Company or such Restricted Subsidiary for such Asset Sale is not less than the Fair Market Value of the shares or other assets sold (as determined by the board of directors of the Company, whose determination shall be conclusive and evidenced by a resolution thereof) and (ii) the consideration received by the Company or the relevant Restricted Subsidiary in respect of such Asset Sale consists of at least 75% cash or Cash Equivalents; provided, however, that for purposes of this Section 1017, "Cash Equivalents" shall include (i) the amount of any liabilities (other than liabilities that are by their terms subordinated to the Notes) of the Company or such Restricted Subsidiary (as shown on the Company's or such Restricted Subsidiary's most recent balance sheet or in the notes thereto) that are assumed by the transferee of any such assets or other property in such Asset Sale or are no longer a liability of the Company or any Restricted Subsidiary (and excluding any liabilities that are incurred in connection with or in anticipation of such Asset Sale), but only to the extent that such assumption is effected on a basis under which there is no further recourse to the Company or any of its Restricted Subsidiaries with respect to such liabilities and (ii) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary in connection with such Asset Sale that are converted by the Company or such Restricted Subsidiary into cash within 60 days of receipt. (b) If the Company or any Restricted Subsidiary engages in an Asset Sale, the Company may use the Net Cash Proceeds thereof, within 12 months after such Asset Sale, to (i) permanently repay or prepay the Notes or any then outstanding Indebtedness of the Company that ranks equally with the Notes or Indebtedness of any Restricted Subsidiary or permanently reduce (without making any prepayment) the amount that is at the time available to be borrowed under the Notes or any Indebtedness of the Company ranking equally with the Notes or any Indebtedness of a Restricted Subsidiary or (ii) invest (or enter into a legally binding agreement to invest) in properties and assets to replace the properties and assets that were the subject of the Asset Sale or in properties and assets that are or will be used in the Telecommunications Business of the Company or a Restricted Subsidiary, as the case may be. If any such legally binding agreement to invest such Net Cash Proceeds is terminated, then the Company may, within 60 days of such termination or within 12 months of such Asset 95 Sale, whichever is later, apply or invest such Net Cash Proceeds as provided in clause (i) or (ii) (without regard to the parenthetical contained in such clause (ii)) above. The amount of such Net Cash Proceeds not so used as set forth above in this paragraph (b) constitutes "Excess Proceeds." (c) When the aggregate amount of Excess Proceeds exceeds $10,000,000, the Company shall, within 15 business days, make an offer to purchase (an "Excess Proceeds Offer"), on a proportional basis, the Notes and Indebtedness described in the second succeeding sentence, in accordance with the procedures set forth below, the maximum principal amount of Notes (expressed as a multiple of $1,000) and such other Indebtedness that may be purchased with the Excess Proceeds. Any Excess Proceeds Offer shall include a pro rata offer under similar circumstances to purchase all other Indebtedness of the Company ranking equally with the Notes which Indebtedness contains similar provisions requiring the Company to purchase such Indebtedness. The offer price as to each Note (the "Excess Proceeds Offer Price") will be payable in cash in an amount equal to 100% of the principal amount of such Note, plus accrued and unpaid interest, if any, thereon to the date of purchase. To the extent that the aggregate principal amount of Notes validly tendered and not withdrawn by holders thereof pursuant to an Excess Proceeds Offer is less than the Excess Proceeds, the Company may use such deficiency for general corporate purposes. If the aggregate principal amount of Notes validly tendered and not withdrawn by holders thereof pursuant to an Excess Proceeds Offer exceeds the Excess Proceeds, Notes to be purchased will be selected on a proportional basis. Upon completion of such Exceeds Proceeds Offer, the amount of Excess Proceeds shall be reset to zero. SECTION 1018. Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction of any kind on the ability of any Restricted Subsidiary to (a) pay dividends, in cash or otherwise, or make any other distributions on or in respect of any Capital Stock of such Restricted Subsidiary owned by the Company or any other Restricted Subsidiary, (b) pay any Indebtedness owed to the Company or any other Restricted Subsidiary, (c) make Investments in the Company or any other Restricted Subsidiary, (d) transfer any of its property or assets to the Company or any other Restricted Subsidiary or (e) guarantee any Indebtedness of the Company or any other Restricted Subsidiary, except for such encumbrances or restrictions existing under or by reason of (i) any agreement in effect on the Issue Date, (ii) applicable law, (iii) customary non-assignment provisions in leases entered into in the ordinary course of business and other agreements of the Company or any Restricted Subsidiary, (iv) any agreement or other instrument of a Person acquired by the Company or any Restricted Subsidiary in existence at the time of such acquisition (but not created in contemplation thereof), 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 96 assets of the Person, so acquired, (v) customary restrictions on transfers of property contained in any security agreement (including a capital lease obligation) securing Indebtedness of the Company or a Restricted Subsidiary otherwise permitted hereunder, (vi) any encumbrance or restriction with respect to a Restricted Subsidiary of the Company entered into for the sale or disposition of all or substantially all of the Capital Stock or assets of such Restricted Subsidiary permitted under Section 1017, (vii) any agreement or instrument governing or relating to Indebtedness under any senior financing facility permitted to be incurred under clause (g), (j) or (m) of the definition of "Permitted Indebtedness" if such encumbrance or restriction applies only (A) to amounts which at any point in time (other than during such periods as are described in the following clause (B)) (1) exceed scheduled amounts due and payable (or which are to become due and payable within 30 days) in respect of the Notes or this Indenture for interest, premium, and Liquidated Damages, if any, and principal less the amount of cash that is otherwise available to the Company at such time for the payment of interest, premium and Liquidated Damages, if any, and principal due and payable in respect of the Notes or this Indenture or (2) if paid, would result in an event described in the following clause (B) of this sentence, or (B) during the pendency of any event that causes, permits or, after notice or lapse of time, would cause or permit the holder or holders of such Indebtedness to declare such Indebtedness to be immediately due and payable or to require cash collateralization or cash cover for such Indebtedness for so long as such cash collateralization or cash cover has not been provided; (viii) any encumbrance or restriction under the Vendor Credit Facility; (ix) any encumbrance or restriction relating to transfer of property or assets comprising an Initial System pursuant to an Incumbent Agreement, and (x) any encumbrance or restriction under any agreement that extends, renews, refinances or replaces agreements containing the encumbrances or restrictions in the foregoing clauses (i) through (vi) and (viii), so long as the Board of Directors of the Company determines in good faith that the terms and conditions of any such encumbrances or restrictions, taken as a whole, are no less favorable to the Company, any Restricted Subsidiary and the holders of the Notes than those so extended, renewed, refinanced or replaced. SECTION 1019. Waiver of Certain Covenants. The Company may omit in any particular instance to comply with any term, provision or condition set forth in Section 803 or Sections 1005 through 1018, inclusive, if before or after the time for such compliance the Holders of at least a majority in aggregate principal amount of the Outstanding Notes, by Act of such Holders, waive such compliance in such instance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 97 ARTICLE ELEVEN REDEMPTION OF NOTES SECTION 1101.

Security. (a) On the Issue Date, the Company shall purchase, and at all times, subject to the Pledge Agreement, pledge to the Trustee the Pledged Securities as security for the benefit of the Holders. The Pledged Securities must be in such amount as will be sufficient upon receipt of scheduled interest on and principal payments of such Pledged Securities, in the opinion of a nationally recognized firm of independent public accountants selected by the Company, to provide for payment in full of the first four scheduled interest payments due on the Outstanding Notes. The Pledged Securities shall be pledged by the Company to the Trustee for the benefit of the Holders pursuant to the Pledge Agreement and shall be held by the Trustee in the Escrow Account pending disposition pursuant to the Pledge Agreement. (b) Each Holder, by its acceptance of a Note, consents and agrees to the terms of the Pledge Agreement (including, without limitation, the provisions providing for foreclosure and release of the Pledged Securities) as the same may be in effect or may be amended from time to time in accordance with its terms, and authorizes and directs the Trustee to enter into the Pledge Agreement and to perform its respective obligations and exercise its respective rights thereunder in accordance therewith. The Company shall do or cause to be done all such acts and things as may be reasonably necessary or proper, or as may be required by the provisions of the Pledge Agreement, to assure and confirm to the Trustee the security interest in the Pledged Securities contemplated hereby, by the Pledge Agreement or any part thereof, as from time to time constituted, so as to render the same available for the security and benefit of this Indenture and of the Notes secured hereby, according to the intent and purposes herein expressed.

(c) The release of any Pledged Securities pursuant to the Pledge Agreement will not be deemed to impair the security under this Indenture in contravention of the provisions hereof if and to the extent the Pledged Securities are released pursuant to this Indenture and the Pledge Agreement. To the extent applicable, the Company shall cause TIA Section 314(d), relating to the release of property or securities from the Lien and security interest of the Pledge Agreement and relating to the substitution therefor of any property or securities to be subjected to the Lien and security interest of the Pledge Agreement, to be complied with.

(d) The Company shall cause TIA Section 314(b), relating to opinions of counsel regarding the Lien under the Pledge Agreement, to be complied with.

ARTICLE THIRTEEN DEFEASANCE AND COVENANT DEFEASANCE SECTION 1301. Company's Option to Effect Defeasance or Covenant Defeasance. The Company may, at its option by Board Resolution, at any time, with respect to the Notes, elect to have either Section 1302 or Section 1303 be applied to all Outstanding Notes upon compliance with the conditions set forth below in this Article Thirteen. SECTION 1302. Defeasance and Discharge. Upon the Company's exercise under Section 1301 of the option applicable to this Section 1302, the Company shall be deemed to have been discharged from its obligations with respect to all Outstanding Notes on the date the conditions set forth in Section 1304 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 102 the Outstanding Notes, which shall thereafter be deemed to be "Outstanding" only for the purposes of Section 1305 and the other Sections of this Indenture referred to in (A) and (B) below, and to have satisfied all its other obligations under such Notes and this Indenture insofar as such Notes 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 Notes to receive, solely from the trust fund described in Section 1304 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any, on) and interest and Liquidated Damages, if any, on such Notes when such payments are due, (B) the Company's obligations with respect to such Notes under Sections 304, 305, 306, 1002 and 1003, (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (D) this Article Thirteen. Subject to compliance with this Article Thirteen, the Company may exercise its option under this Section 1302 notwithstanding the prior exercise of its option under Section 1303 with respect to the Notes. SECTION 1303. Covenant Defeasance. Upon the Company's exercise under Section 1301 of the option applicable to this Section 1303, the Company shall be released from its obligations under any covenant contained in Section 801(2) and (3) and Section 803 and in Sections 1007 through 1018 with respect to the Outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, "covenant defeasance"), and the Notes shall thereafter be deemed not to be "Outstanding" for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed "Outstanding" for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to the Outstanding Notes, 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 covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 501(4), but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. SECTION 1304. Conditions to Defeasance or Covenant Defeasance. The following shall be the conditions to application of either Section 1302 or Section 1303 to the Outstanding Notes: (1) The Company shall have deposited or caused to be deposited irrevocably with the Trustee (or another trustee satisfying the requirements of Section 607 who shall agree to comply with the provisions of this Article Thirteen applicable to it) 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 Notes, (A) cash 103 in United States dollars, (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 public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (i) the principal of (and premium, if any) and interest and Liquidated Damages, if any, on, Outstanding Notes on the Stated Maturity (or Redemption Date, if applicable) of such principal (and premium, if any) or installment of interest and Liquidated Damages, if any, and (ii) any payments applicable to the Outstanding Notes on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Notes; provided that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such U.S. Government Obligations to said payments with respect to the Notes. Before such a deposit, the Company may give to the Trustee, in accordance with Section 1103 hereof, a notice of its election to redeem all of the Outstanding Notes at a future date in accordance with Article Eleven hereof, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing. For this purpose, "U.S. Government Obligations" means securities that are (x) direct obligations of the United States of America for the timely 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 timely 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 depository receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act of 1933, as amended), 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 depository 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 depository 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 depository receipt. (2) No Default or Event of Default with respect to the Notes shall have occurred and be continuing on the date of such deposit or, insofar as paragraphs (6) and (7) of Section 501 hereof are concerned, at any time during the period ending on the 123rd 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 result in a breach or violation of, or constitute a default under any material agreement or instrument (other than the Indenture) to which the Company is a party or by which it is bound. 104 (4) In the case of an election under Section 1302, 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 April 1, 1998, 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 Notes will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred. (5) In the case of an election under Section 1303, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the Outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to U.S. 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. (6) 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 1302 or the covenant defeasance under Section 1303 (as the case may be) have been complied with. SECTION 1305. 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 1305, the "Trustee") pursuant to Section 1304 in respect of the Outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes 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 Notes 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. Governmental Obligations deposited pursuant to Section 1304 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 Notes. Anything in this Article Thirteen to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or 105 U.S. Government Obligations held by it as provided in Section 1304 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent defeasance or covenant defeasance, as applicable, in accordance with this Article. SECTION 1306. Reinstatement. If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 1305 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 Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 1302 or 1303, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 1305; provided, however, that if the Company makes any payment of principal of (or premium, if any) or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 106 This Indenture may be signed 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 Indenture.
