ARTICLE II
THE NOTES

SECTION 2.01. Amount of Notes.

The Trustee shall initially authenticate (a) Notes for original issue on the Issue Date in an aggregate principal amount at maturity of $515,000,000 upon a written order of the Issuer in the form of an Officers' Certificate of the Issuer; and (b) Unrestricted Securities from time to time only in exchange for a like principal amount at maturity of Notes in each case upon a written order of the Issuer in the form of an Officers' Certificate. The Trustee shall authenticate Notes thereafter in unlimited amount (so long as permitted by the terms of this Indenture, including, without limitation, Section 4.10) (any such Notes, the "Additional Notes") for original issue upon a written order of the Issuer in the form of an Officers' Certificate in aggregate principal amount at maturity as specified in such order. Each such written order shall specify the principal amount at maturity of Notes to be authenticated and the date on which the Notes are to be authenticated.

SECTION 2.02. Form and Dating.

The Notes and the Trustee's certificate of authentication shall be substantially in the form of Exhibit A hereto, which is incorporated in and forms a part of this Indenture. The Notes may have notations, legends or endorsements required by law, rule or usage to which the Issuer is subject. Without limiting the generality of the foregoing, Notes offered and sold to Qualified Institutional Buyers in reliance on Rule 144A ("Rule 144A Notes") shall bear the legend and include the form of assignment set forth in Exhibit B, Notes offered and sold in offshore transactions in reliance on Regulation S ("Regulation S Notes") shall bear the legend and include the form of assignment set forth in Exhibit C, and Notes offered and sold to Institutional Accredited Investors in transactions exempt from registration under the Securities Act not made in reliance on Rule 144A or Regulation S ("Other Notes") may be represented by a Restricted Global Note or, if such an investor may not hold an interest in the Restricted Global Note, a Physical Note, in each case, bearing the Private Placement Legend. The Issuer shall approve the form of the Notes and any notation, legend or endorsement on them. Each Note shall be dated the date of its issuance and show the date of its authentication.

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Issuer and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and agree to be bound thereby.

The Notes may be presented for registration of transfer and exchange at the offices of the Registrar.

Notes issued in exchange for interests in a Global Note pursuant to Section 2.16 may be issued in the form of permanent certificated Notes in registered form in substantially the form set forth in Exhibit A (the "Physical Notes").

SECTION 2.03. Execution and Authentication.

One Officer, who shall have been duly authorized by all requisite corporate actions, shall sign the Notes for the Issuer by manual or facsimile signature.

If the Officer whose signature is on a Note was an Officer at the time of such execution but no longer holds that office at the time the Trustee authenticates the Note, the Note shall be valid nevertheless.

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Note shall have been authenticated and delivered hereunder but never issued and sold by the Issuer, and the Issuer shall deliver such Note to the Trustee for cancellation as provided in Section 2.12, for all purposes of this Indenture such Note shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to authenticate the Notes. Unless otherwise provided in the appointment, an authenticating agent may authenticate the Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Issuer and Affiliates of the Issuer. Each Paying Agent is designated as an authenticating agent for purposes of this Indenture.

The Notes shall be issuable only in registered form without coupons in denominations of $1,000 principal at maturity and any integral multiple of $1,000.

SECTION 2.04. Registrar and Paying Agent.

The Issuer shall maintain an office or agency in the Borough of Manhattan, The City of New York, where (a) Notes may be presented or surrendered for registration of transfer or for exchange ("Registrar"), (b) Notes may be presented or surrendered for payment ("Paying Agent") and (c) notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served. The Issuer may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Issuer of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Issuer may act as its own Registrar or Paying Agent, except that for the purposes of Articles Three and Eight and Sections 4.09 and 4.13, neither the Issuer nor any Affiliate of the Issuer shall act as Paying Agent. The Registrar shall keep a register of the Notes and of their transfer and exchange. The Issuer, upon notice to the Trustee, may have one or more co-Registrars and one or more additional paying agents reasonably acceptable to the Trustee. The term "Paying Agent" includes any additional paying agent. The Issuer initially appoints the Trustee as Registrar and Paying Agent until such time as the Trustee has resigned and a successor has been appointed.

The Issuer shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which agreement shall implement the provisions of this Indenture that relate to such Agent. The Issuer shall notify the Trustee, in advance, of the name and address of any such Agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such.

SECTION 2.05. Paying Agent To Hold Assets in Trust.

The Issuer shall require each Paying Agent other than the Trustee to agree in writing that each Paying Agent shall hold in trust for the benefit of Holders or the Trustee all assets held by the Paying Agent for the payment of, principal or Accreted Value of, premium, if any, or interest on, the Notes (whether such assets have been distributed to it by the Issuer or any other obligor on the Notes), and shall notify the Trustee of any Default by the Issuer (or any other obligor on the Notes) in making any such payment. The Issuer at any time may require a Paying Agent to promptly distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the continuance of any payment Default, upon written request to a Paying Agent, require such Paying Agent to promptly distribute all assets held by it to the Trustee and to account for any assets distributed. Upon distribution to the Trustee of all assets that shall have been delivered by the Issuer to the Paying Agent, the Paying Agent shall have no further liability for such assets.

SECTION 2.06. Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee at least two (2) Business Days prior to each Interest Payment Date and at such other times as the Trustee may request in writing a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders, which list may be conclusively relied upon by the Trustee.

SECTION 2.07. Transfer and Exchange.

Subject to Sections 2.16 and 2.17, when Notes are presented to the Registrar or a co-Registrar with a request to register the transfer of such Notes or to exchange such Notes for an equal principal amount at maturity of Notes of other authorized denominations, the Registrar or co-Registrar shall promptly register the transfer or make the exchange as requested if its requirements for such transaction are met; provided, however, that the Notes surrendered for transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Registrar or co-Registrar, duly executed by the Holder thereof or his or her attorney duly authorized in writing. To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Notes at the Registrar's or co-Registrar's request. No service charge shall be made for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith.

The Registrar or co-Registrar shall not be required to register the transfer of or exchange of any Note (i) during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Notes and ending at the close of business on the day of such mailing, (ii) selected for redemption in whole or in part pursuant to Article III, except the unredeemed portion of any Note being redeemed in part, and (iii) during a Change of Control Offer or an Asset Sale Offer if such Note is tendered pursuant to such Change of Control Offer or Asset Sale Offer and not withdrawn.

Any Holder of a beneficial interest in a Global Note shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Notes may be effected only through a book-entry system maintained by the Holder of such Global Note (or its agent), and that ownership of a beneficial interest in the Note shall be required to be reflected in a book-entry system.

SECTION 2.08. Replacement Notes.

If a mutilated Note is surrendered to the Registrar or the Trustee, or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note if the Holder of such Note furnishes to the Issuer and the Trustee evidence reasonably acceptable to them of the ownership and the destruction, loss or theft of such Note and if the requirements of Section 8-405 of the New York Uniform Commercial Code as in effect on the date of this Indenture are met. If required by the Trustee or the Issuer, an indemnity bond shall be posted, sufficient in the judgment of all to protect the Issuer, if any, the Trustee or any Paying Agent from any loss that any of them may suffer if such Note is replaced. The Issuer may charge such Holder for the Issuer's reasonable out-of-pocket expenses in replacing such Note and the Trustee may charge the Issuer for the Trustee's expenses (including, without limitation, attorneys' fees and disbursements) in replacing such Note. Every replacement Note shall constitute a contractual obligation of the Issuer.

SECTION 2.09. Outstanding Notes.

The Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Note does not cease to be outstanding because the Issuer or any of its Affiliates holds the Note (subject to the provisions of Section 2.10).

If a Note is replaced pursuant to Section 2.08 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless a Responsible Officer of the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.08.

If the principal or Accreted Value of any Note is considered paid under Section 4.01, it ceases to be outstanding and interest ceases to accrue. If on a Redemption Date or the Maturity Date the Trustee or Paying Agent (other than the Issuer or an Affiliate thereof) holds U.S. Legal Tender or Government Securities sufficient to pay all of the Accreted Value of, premium, if any, and interest due on the Notes payable on that date, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue.

SECTION 2.10. Treasury Notes.

In determining whether the Holders of the required principal amount at maturity of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or any of its Affiliates shall be disregarded, except that, for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be disregarded.

SECTION 2.11. Temporary Notes.

Until definitive Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. Until such exchange, temporary Notes shall be entitled to the same rights, benefits and privileges as definitive Notes. Notwithstanding the foregoing, so long as the Notes are represented by a Global Note, such Global Note may be in typewritten form.

SECTION 2.12. Cancellation.

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent (other than the Issuer or a Subsidiary), and no one else, shall cancel and, at the written direction of the Issuer, shall dispose of all Notes surrendered for transfer, exchange, payment or cancellation in accordance with its customary procedures. Subject to Section 2.08, the Issuer may not issue new Notes to replace Notes that it has paid or delivered to the Trustee for cancellation. If the Issuer shall acquire any of the Notes, 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 pursuant to this Section 2.12.

SECTION 2.13. Defaulted Interest.

If the Issuer defaults in a payment of interest on the Notes, it shall, unless the Trustee fixes another record date pursuant to Section 6.10, pay the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest, in any lawful manner. The Issuer may pay the defaulted interest to the persons who are Holders on a subsequent special record date, which special record date shall be the fifteenth day next preceding the date fixed by the Issuer for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. At least 15 days before any such subsequent special record date, the Issuer shall mail to each Holder, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid. The Issuer may make payment of any defaulted interest in any other lawful manner not inconsistent with the requirements (if applicable) of any securities exchange on which the Notes may be listed and, upon such notice as may be required by such exchange, if, after written notice given by the Issuer to the Trustee of the proposed payment pursuant to this sentence, such manner of payment shall be deemed practicable by the Trustee.

SECTION 2.14. CUSIP Number.

The Issuer in issuing the Notes may use a "CUSIP" number, and if so, the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer will promptly notify the Trustee of any change in the CUSIP numbers.

SECTION 2.15. Deposit of Moneys.

Prior to 10:00 a.m. New York City time on each Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Excess Proceeds Payment Date, the Issuer shall have deposited with the Paying Agent in immediately available funds money sufficient to make cash payments, if any, due on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Excess Proceeds Offer Payment Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Excess Proceeds Payment Date, as the case may be. The Accreted Value, premium and interest on Global Notes shall be payable to the Depositary or its nominee, as the case may be, as the sole registered owner and the sole Holder of the Global Notes represented thereby. The principal amount at maturity and interest on Physical Notes shall be payable, either in person or by mail, at the office of the Paying Agent.

SECTION 2.16. Book-Entry Provisions for Global Notes.

(a) Rule 144A Notes and Other Notes shall be represented by one or more notes in registered, global form without interest coupons (collectively, the "Restricted Global Note"). Regulation S Notes initially shall be represented by one or more notes in registered, global form without interest coupons (collectively, the "Regulation S Global Note," and, together with the Restricted Global Note and any other global notes representing Notes, the "Global Notes"). The Global Notes shall bear legends as set forth in Exhibit D. The Global Notes initially shall (i) be registered in the name of the Depositary or the nominee of such Depositary, in each case for credit to an account of an Agent Member, (ii) be delivered to the Trustee as custodian for such Depositary and (iii) bear legends as set forth in Exhibit B with respect to Restricted Global Notes and Exhibit C with respect to Regulation S Global Notes.

Members of, or direct or indirect participants in, the Depositary ("Agent Members") shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Notes, and the Depositary may be treated by the Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute owner of the Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer 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 Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note.

(b) Transfers of Global Notes shall be limited to transfer in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in the Global Notes may be transferred or exchanged for Physical Notes in accordance with the rules and procedures of the Depositary and the provisions of Section 2.17. In addition, a Global Note shall be exchangeable for Physical Notes if (i) requested by a Holder of such interests or (ii) the Depositary notifies the Issuer that it is unwilling or unable to continue as depository for such Global Note and the Issuer thereupon fails to appoint a successor depositary within 90 days. In all cases, Physical Notes delivered in exchange for any Global Note or beneficial interests therein shall be registered in the names, and issued in any approved denominations, requested by or on behalf of the Depositary (in accordance with its customary procedures).

(c) In connection with any transfer or exchange of a portion of the beneficial interest in any Global Note to beneficial owners pursuant to paragraph (b), the Registrar shall (if one or more Physical Notes are to be issued) reflect on its books and records the date and a decrease in the principal amount at maturity of the Global Note in an amount equal to the principal amount at maturity of the beneficial interest in the Global Note to be transferred, and the Issuer shall execute, and the Trustee shall upon receipt of a written order from the Issuer authenticate and make available for delivery, one or more Physical Notes of like tenor and amount.

(d) In connection with the transfer of Global Notes as an entirety to beneficial owners pursuant to paragraph (b), the Global Notes shall be deemed to be surrendered to the Trustee for cancellation, and the Issuer shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in writing in exchange for its beneficial interest in the Global Notes, an equal aggregate principal amount at maturity of Physical Notes of authorized denominations.

(e) Any Physical Note constituting a Restricted Security delivered in exchange for an interest in a Global Note pursuant to paragraph (b), (c) or (d) shall, except as otherwise provided by paragraphs (a)(i)(x) and (c) of Section 2.17, bear the Private Placement Legend or, in the case of the Regulation S Global Note, the legend set forth in Exhibit C, in each case, unless the Issuer determines otherwise in compliance with applicable law.

(f) On or prior to the end of the "distribution compliance period" (as defined in Regulation S, the "Restricted Period"), a beneficial interest in a Regulation S Global Note may be transferred to a Person who takes delivery in the form of an interest in the corresponding Restricted Global Note only upon receipt by the Trustee of a written certification from the transferor to the effect that such transfer is being made (i) (a) to a Person that the transferor reasonably believes is a Qualified Institutional Buyer in a transaction meeting the requirements of Rule 144A or (b) pursuant to another exemption from the registration requirements under the Securities Act which is accompanied by an Opinion of Counsel regarding the availability of such exemption and (ii) in accordance with all applicable securities laws of any state of the United States or any other jurisdiction.

(g) Beneficial interests in the Restricted Global Note may be transferred to a Person who takes delivery in the form of an interest in the Regulation S Global Note, whether before or after the expiration of the Restricted Period, only if the transferor first delivers to the Trustee a written certificate to the effect that such transfer is being made in accordance with Regulation S or Rule 144 (if available).

(h) 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 another Global Note shall, upon transfer, cease to be an interest in such Global Note and become an interest in such other Global Note and, accordingly, shall thereafter be subject to all transfer restrictions and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest.

(i) The Holder of any Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes.

SECTION 2.17. Special Transfer Provisions.

(a) Transfers to Non-QIB Institutional Accredited Investors and Non-U.S. Persons. The following provisions shall apply with respect to the registration of any proposed transfer of a Note constituting a Restricted Security to any Institutional Accredited Investor which is not a QIB or to any Non-U.S. Person:

(i) the Registrar shall register the transfer of any Note constituting a Restricted Security, whether or not such Note bears the Private Placement Legend, if (x) the requested transfer is after the second anniversary of the date of original issuance thereof or such other date as such Note shall be freely transferable under Rule 144 as certified in an Officers' Certificate or (y) (1) in the case of a transfer to an Institutional Accredited Investor which is not a QIB (excluding Non-U.S. Persons), the proposed transferee has delivered to the Registrar a certificate substantially in the form of Exhibit E hereto or (2) in the case of a transfer to a Non-U.S. Person (including a QIB), the proposed transferor has delivered to the Registrar a certificate substantially in the form of Exhibit F hereto; provided that, in the case of any transfer of a Note bearing the Private Placement Legend for a Note not bearing the Private Placement Legend, the Registrar has received an Officers' Certificate authorizing such transfer; and;

(ii) if the proposed transferor is an Agent Member holding a beneficial interest in a Global Note, upon receipt by the Registrar of (x) the certificate, if any, required by paragraph (i) above and (y) instructions given in accordance with the Depositary's and the Registrar's procedures,

whereupon (a) the Registrar shall reflect on its books and records the date and (if the transfer does not involve a transfer of outstanding Physical Notes) a decrease in the principal amount at maturity of a Global Note in an amount equal to the principal amount at maturity of the beneficial interest in a Global Note to be transferred, and (b) the Registrar shall reflect on its books and records the date and an increase in the principal amount at maturity of a Global Note in an amount equal to the principal amount at maturity of the beneficial interest in the Global Note transferred or the Issuer shall execute and the Trustee shall authenticate and make available for delivery one or more Physical Notes of like tenor and amount.

(b) Transfers to QIBs. The following provisions shall apply with respect to the registration or any proposed registration of transfer of a Note constituting a Restricted Security to a QIB (excluding transfers to Non-U.S. Persons):

(i) the Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on such Holder's Note stating, or to a transferee who has advised the Issuer and the Registrar in writing, that it is purchasing the Note for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Issuer as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; and

(ii) if the proposed transferee is an Agent Member, and the Notes to be transferred consist of Physical Notes which after transfer are to be evidenced by an interest in the Global Note, upon receipt by the Registrar of instructions given in accordance with the Depositary's and the Registrar's procedures, the Registrar shall reflect on its books and records the date and an increase in the principal amount at maturity of the Global Note in an amount equal to the principal amount at maturity of the Physical Notes to be transferred, and the Trustee shall cancel the Physical Notes so transferred.

(c) Private Placement Legend. Upon the registration of transfer, exchange or replacement of Notes not bearing the Private Placement Legend, the Registrar shall deliver Notes that do not bear the Private Placement Legend. Upon the registration of transfer, exchange or replacement of Notes bearing the Private Placement Legend, the Registrar shall deliver only Notes that bear the Private Placement Legend unless (i) it has received the Officers' Certificate required by paragraph (a)(i)(y) of this Section 2.17, (ii) there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Issuer and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act or (iii) such Note has been sold pursuant to an effective registration statement under the Securities Act and the Registrar has received an Officers' Certificate from the Issuer to such effect or such Note has been exchanged in the exchange offer under the Registration Rights Agreement.

(d) General. By its acceptance of any Note bearing the Private Placement Legend, each Holder of such Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Note only as provided in this Indenture.

The Registrar shall retain for a period of two years copies of all letters, notices and other written communications received pursuant to Section 2.16 or this Section 2.17. The Issuer shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable notice to the Registrar.

The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in the Depositary or other Person with respect to the accuracy of the books or records, or the acts or omissions, of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depository or its nominee on the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the applicable procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants, members or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

SECTION 2.18. Computation of Interest.

Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months and actual days elapsed.

ARTICLE III
REDEMPTION

SECTION 3.01. Notices to Trustee.

If the Issuer elects to redeem Notes pursuant to Section 5, 6 or 7 of the Notes, it shall notify the Trustee in writing of the Redemption Date, the Redemption Price and the principal amount at maturity of Notes to be redeemed. Subject to Section 3.03, the Issuer shall give notice of redemption to the Paying Agent and Trustee at least 30 days but not more than 60 days before the Redemption Date (unless a shorter notice shall be agreed to by the Trustee in writing), together with an Officers' Certificate stating that such redemption will comply with the conditions contained herein.

SECTION 3.02. Selection of Notes To Be Redeemed.

If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption as follows:

(1) by lot; or

(2) if such method is prohibited by the rules of any stock exchange on which the Notes are listed, by such method as the Trustee deems reasonable.

No Notes of a principal amount at maturity of $1,000 or less shall be redeemed in part.

SECTION 3.03. Notice of Redemption.

At least 30 days but not more than 60 days before a Redemption Date, the Issuer shall mail a notice of redemption by first class mail, postage prepaid, to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture. At the Issuer's request, the Trustee shall forward the notice of redemption in the Issuer's name and at the Issuer's expense; provided that, in such case, the Trustee has received notice from the Issuer at least 45 days, but not more than 60 days, before a Redemption Date (unless a shorter notice shall be agreed to in writing by the Trustee). Notes called for redemption become due on the date fixed for redemption. On and after the Redemption Date, interest ceases to accrue on Notes or portions of them called for redemption. Each notice of redemption shall identify the Notes (including the CUSIP number) to be redeemed and shall state:

(1) the Redemption Date;

(2) the Redemption Price and the amount of accrued interest, if any, to be paid;

(3) the name and address of the Paying Agent;

(4) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price plus accrued interest, if any;

(5) that, unless the Issuer defaults in making the redemption payment, Accreted Value or interest on Notes called for redemption ceases to accrete or accrue, as the case may be, on and after the Redemption Date, and the only remaining right of the Holders of such Notes is to receive payment of the Redemption Price upon surrender to the Paying Agent of the Notes redeemed;

(6) if any Note is being redeemed in part, the portion of the principal amount at maturity of such Note to be redeemed and that, after the Redemption Date, and upon surrender of such Note, a new Note or Notes in aggregate principal amount at maturity equal to the unredeemed portion thereof will be issued;

(7) if fewer than all the Notes are to be redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount at maturity of Notes to be redeemed and the aggregate principal amount at maturity of Notes to be outstanding after such partial redemption; and

(8) the Section of the Notes pursuant to which the Notes are to be redeemed.

The notice, if mailed in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Notices of redemption may not be conditional.

SECTION 3.04. Effect of Notice of Redemption.

Once notice of redemption is mailed in accordance with Section 3.03, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price plus accrued interest, if any. Upon surrender to the Trustee or Paying Agent, such Notes called for redemption shall be paid at the Redemption Price (which shall include accrued interest thereon to the Redemption Date), but installments of interest, the maturity of which is on or prior to the Redemption Date, shall be payable to Holders of record at the close of business on the relevant Record Dates. On and after the Redemption Date interest shall cease to accrue on Notes or portions thereof called for redemption.

SECTION 3.05. Deposit of Redemption Price.

On or before 10:00 a.m. New York time on the Redemption Date, the Issuer shall deposit with the Paying Agent U.S. Legal Tender sufficient to pay the Redemption Price plus accrued interest, if any, of all Notes to be redeemed on that date.

If the Issuer complies with the preceding paragraph, then, unless the Issuer defaults in the payment of such Redemption Price plus accrued interest, if any, on the Notes to be redeemed will cease to accrue or accrete interest on and after the applicable Redemption Date, whether or not such Notes are presented for payment.

SECTION 3.06. Notes Redeemed in Part.

If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount at maturity thereof to be redeemed. A new Note in principal amount at maturity equal to the unredeemed portion of the original Note shall be issued in the name of the Holder thereof upon cancellation of the original Note.

without making effective provision for the Notes and all other amounts due under this Indenture to be directly secured equally and ratably with (or, if the Indebtedness or other obligation or liability to be secured by such Lien is subordinated in right of payment to the Notes, prior to) the Indebtedness or other obligation or liability secured by such Lien.

(b) Section 4.12(a) shall not prohibit:

(1) Liens existing on the Issue Date;

(2) Liens securing Indebtedness under the Nortek Credit Facility;

(3) Liens securing Indebtedness of a Restricted Subsidiary that is permitted to be incurred under Section 4.10; provided that this clause (3) will only permit Liens securing Indebtedness incurred by Nortek if such Indebtedness constitutes Senior Indebtedness of Nortek;

(7) Permitted Liens.

SECTION 4.13. Limitation on Use of Proceeds from Asset Sales.

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, consummate an Asset Sale unless:

(1) the Issuer or such Restricted Subsidiary, as the case may be, receives consideration at the time of any such Asset Sale having a value (including the Fair Market Value of any non-cash consideration) at least equal to the Fair Market Value of the securities or assets being sold or otherwise disposed of, and

(2) at least 75% of the consideration from such Asset Sale is received in the form of cash, Cash Equivalents (together with cash, "Cash Proceeds") or indebtedness for borrowed money of the Issuer or such Restricted Subsidiary that is assumed by the transferee of any such assets or any such indebtedness of any Restricted Subsidiary of the Issuer whose stock is purchased by the transferee.

(b) Any Net Cash Proceeds

(1) in excess of the amount of cash applied by the Issuer or any Restricted Subsidiary of the Issuer during the period beginning 12 months prior to the date of the Asset Sale and ending 12 months after the date of such Asset Sale to purchase any business that is, or any properties and assets used primarily in, the same or a related business as those owned and operated by the Issuer and its Subsidiaries as of the Issue Date or at the date of such Asset Sale and

(2) not applied within 13 months after the date of the Asset Sale to reduce Indebtedness under the Nortek Credit Agreement, Indebtedness of a Restricted Subsidiary or other Indebtedness of the Issuer that ranks pari passu with the Notes (provided that if the Issuer shall so reduce Indebtedness of the Issuer that ranks pari passu with the Notes, it will equally and ratably reduce Indebtedness under the Notes by making an offer (in accordance with the procedures set forth below for an Excess Proceeds Offer) to all Holders to purchase a pro rata amount of Accreted Value of the Notes at a purchase price equal to 100% of the Accreted Value thereof, plus accrued and unpaid interest, if any)

shall be deemed to be "Excess Proceeds"; provided that, if an offer to purchase any Indebtedness of Nortek or any of its Restricted Subsidiaries is made in accordance with the terms of such Indebtedness, the obligation to reduce the Indebtedness of such Restricted Subsidiary will be deemed to be satisfied to the extent of the amount of the offer, whether or not accepted by the holders thereof, and no Excess Proceeds in the amount of such offer will be deemed to exist following such offer.

(c) When the aggregate amount of Excess Proceeds exceeds $10 million, the Issuer shall make an offer (the "Excess Proceeds Offer") to apply the Excess Proceeds to purchase the Notes. The Excess Proceeds Offer must be in cash in an amount equal to 100% of the Accreted Value of the Notes plus accrued and unpaid interest, if any, thereon to the date fixed for the closing of such offer, substantially in accordance with the procedures set forth below.

(d) To the extent that the aggregate Accreted Value of Notes tendered pursuant to the Excess Proceeds Offer is less than the Excess Proceeds, the Issuer may use the remaining Excess Proceeds for general corporate purposes and such amounts shall no longer be deemed Excess Proceeds. If the aggregate Accreted Value of Notes surrendered by Holders exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to be purchased on a pro rata basis, subject to the limitation on the authorized denominations of the Notes.

(e) Immediately following any Excess Proceeds Offer, the Issuer is required to mail a notice to the Trustee and to each Holder stating:

(i) that the Excess Proceeds Offer is being made pursuant to this Section 4.13 and that all Notes tendered will be accepted for payment;

(ii) the amount of the Excess Proceeds Payment and the purchase date (the "Excess Proceeds Payment Date"), which may not be earlier than 30 days nor later than 60 days from the date such notice is mailed;

(iii) that any Note not tendered will continue to accrete or accrue interest;

(iv) that, unless the Issuer defaults in the payment thereof, all Notes accepted for payment pursuant to the Excess Proceeds Offer will cease to accrete or accrue interest on and after the Excess Proceeds Payment Date;

(v) that Holders electing to have any Notes purchased pursuant to an Excess Proceeds Offer will be required to surrender the Notes to be purchased to the Paying Agent at the address specified in the notice prior to the close of business on the third business day preceding the Excess Proceeds Payment Date;

(vi) that Holders will be entitled to withdraw Notes they have tendered on the terms and conditions set forth in such notice; and

(vii) that Holders whose Notes are being purchased only in part will be issued new notes (or book-entry notation made with respect thereto) equal in principal amount at maturity to the unpurchased portion of the Notes tendered; provided that the portion of each Note purchased and each such new note issued (or book-entry notation, if applicable) shall be in a principal amount of $1,000 at maturity or an integral multiple thereof.

(f) On the Excess Proceeds Payment Date, the Issuer will, to the extent lawful:

(i) accept for payment all Notes or portions thereof tendered pursuant to the Excess Proceeds Offer and not withdrawn;

(ii) deposit with the Paying Agent an amount sufficient to pay the Excess Proceeds Payment in respect of all Notes or portions thereof so tendered and not withdrawn; and

(iii) deliver or cause to be delivered to the Trustee all Notes so tendered and not withdrawn together with an Officers' Certificate specifying the Notes or portions thereof tendered to the Issuer.

(g) The Paying Agent will promptly mail to each Holder of Notes so tendered and not withdrawn the Excess Proceeds Payment in respect of such Notes, and the Trustee will promptly authenticate and mail to such Holder a new Note (or cause to be transferred by book entry) equal in principal amount at maturity to any unpurchased portion of the Notes surrendered; provided that each such new Note shall be in a principal amount at maturity of $1,000 or an integral multiple thereof. The Issuer will publicly announce the results of the Excess Proceeds Offer on or as soon as practicable after the Excess Proceeds Payment Date.

(h) The Issuer will comply, and will cause any third party making an Excess Proceeds of Control Offer to comply, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with Excess Proceeds Offer. To the extent the provisions of any applicable securities laws or regulations conflict with the provisions of this Indenture relating to an Excess Proceeds Offer, the Issuer will not be deemed to have breached its obligations under this Indenture by virtue of complying with such laws or regulations.

SECTION 4.14. Limitation on Transactions with Affiliates.

(a) Except as otherwise permitted under this Indenture, the Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, make any Investment, loan, advance, guarantee or capital contribution to, or for the benefit of, or sell, lease or otherwise transfer or dispose of any of its properties or assets to, or for the benefit of, or purchase or lease any property or assets from, or enter into or amend any contract, agreement or understanding with, or for the benefit of, any Affiliate of the Issuer or any of its Restricted Subsidiaries, unless:

(1) such transaction or series of transactions is in the best interests of the Issuer or such Restricted Subsidiary based on all relevant facts and circumstances;

(2) such transaction or series of transactions is fair to the Issuer or such Restricted Subsidiary and on terms that are no less favorable to the Issuer or such Restricted Subsidiary, as the case may be, than those that could have been obtained in a comparable transaction on an arm's-length basis from a Person that is not an Affiliate of the Issuer or any of its Restricted Subsidiaries; and

(3) (a) with respect to a transaction or series of transactions involving aggregate payments in excess of $5 million, the Board of Directors and a majority of the Disinterested Directors shall approve such transaction or series of transactions by a Board Resolution evidencing their determination that such transaction or series of transactions complies with clauses (1) and (2) above, and (b) with respect to a transaction or series of transactions involving aggregate payments equal to or greater than $15 million, the Issuer receives a written opinion from a nationally recognized investment bank or valuation firm or, with respect to a transaction requiring the valuation of real property, a nationally recognized real estate appraisal firm, that such transaction or series of transactions is fair to the Issuer or such Restricted Subsidiary from a financial point of view.

(b) Section 4.14(a) shall prohibit:

(1) any payment of money or issuance of securities by the Issuer or any Restricted Subsidiary of the Issuer pursuant to employment agreements or arrangements and employee benefit plans, including reimbursement or advancement of out-of-pocket expenses and directors' and officers' liability insurance;

(2) reasonable and customary payments and other benefits (including indemnification) provided to directors for service on the Board of Directors of the Issuer or any of its Restricted Subsidiaries and reimbursement of expenses related thereto;

(3) agreements and instruments to which Xxxxx & Company, L.P. or any of its Affiliates is a party which are in effect on the Issue Date or any instruments or securities held by Xxxxx & Company, L.P. or any of its Affiliates on the Issue Date or the payment of fees, reimbursements, indemnifications and other amounts and other transactions pursuant to such agreements, instruments or securities; or

(4) transactions between the Issuer and any Restricted Subsidiary of the Issuer, or between one Restricted Subsidiary of the Issuer and another Restricted Subsidiary of the Issuer; provided that not more than 20% of any such Restricted Subsidiary is owned by any Affiliate of the Issuer or any of its Restricted Subsidiaries (other than the Issuer or a Wholly-Owned Subsidiary of the Issuer which is a Restricted Subsidiary).

SECTION 4.15. Limitations on Certain Restrictions Affecting Subsidiaries.

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or enter into or otherwise cause or permit to exist or become effective any agreement with any Person that would cause any consensual encumbrance or restrictions on the ability of any such Restricted Subsidiary to:

(1) pay dividends or make any other distributions on its Capital Stock or any other interest or participation in, or measured by, its profits, owned by the Issuer or any of its Restricted Subsidiaries,

(2) pay or repay any Indebtedness owed to the Issuer or any of its Restricted Subsidiaries which owns Equity Interests in such Restricted Subsidiary,

(3) make loans or advances to the Issuer or any of its Restricted Subsidiaries which owns Equity Interests in such Restricted Subsidiary,

(4) transfer any of its properties or assets to the Issuer or any of its Restricted Subsidiaries which owns Equity Interests in such Restricted Subsidiary, or

(5) guarantee any Indebtedness of the Issuer or any other Restricted Subsidiary of the Issuer.

(b) Section 4.15(a) will not prohibit encumbrances or restrictions existing under or by reason of:

(1) applicable law,

(2) this Indenture,

(3) customary nonassignment provisions of any lease governing a leasehold interest of the Issuer or any of its Restricted Subsidiaries,

(4) any instrument governing Indebtedness of a Person acquired by the Issuer or any of its Restricted Subsidiaries at the time of such acquisition, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person so acquired,

(5) agreements existing as of the Issue Date,

(6) the Nortek Credit Facility,

(7) the Broan-NuTone Canada, Inc. Credit Facility,

(8) (i) any agreement effecting a refinancing of Indebtedness issued pursuant to any agreement or instrument referred to in clause (4) or (5) above or this clause (8), or (ii) any other agreement pursuant to which any Restricted Subsidiary of the Issuer incurs Indebtedness after the Issue Date in accordance with Section 4.10, and, in each case, either:

(A) the provisions relating to such encumbrance or restriction contained in such Indebtedness are no less favorable to the Issuer, taken as a whole, as determined by the Board of Directors of the Issuer in good faith than the provisions contained in the Nortek Credit Facility or in the indentures governing the Existing Notes, in each case, as in effect on the Issue Date, or

(B) any encumbrance or restriction contained in such Indebtedness is not expected to prohibit (except upon a default or event of default thereunder) the payment of dividends in an amount sufficient, as determined by the Board of Directors of the Issuer in good faith, to make scheduled payments of cash interest on the Notes when due.

(c) The foregoing Sections 4.15(a) and (b) shall not restrict the ability of any Restricted Subsidiary of the Issuer to grant any Lien to the extent otherwise permitted in this Indenture.

SECTION 4.16. Limitation on Guarantees by Certain Subsidiaries.

(a) At any time upon the occurrence of the guarantee of any Indebtedness of the Issuer by any Restricted Subsidiary of the Issuer, the Issuer will cause such Restricted Subsidiary to execute a guarantee, satisfactory in form and substance to the Trustee (and with such documentation relating thereto as the Trustee shall require, including, without limitation, the execution of a supplemental guarantee and opinions of counsel as to the enforceability of such guarantee), pursuant to which such Restricted Subsidiary will fully and unconditionally guarantee the Notes; provided, however, that if such assumption, guarantee or other liability of such Restricted Subsidiary is provided in respect of Indebtedness that is expressly subordinated to the Notes, the guarantee or other instrument provided by such Restricted Subsidiary in respect of such subordinated Indebtedness shall be subordinated to the guarantee of the Notes pursuant to customary subordination provisions.

(b) Notwithstanding the foregoing Section 4.16(a) and the other provisions of this Indenture, any guarantee by a Restricted Subsidiary shall provide by its terms that it shall be automatically and unconditionally released and discharged upon (i) any sale, exchange or transfer to any Person not an Affiliate of the Issuer of a majority of the Capital Stock or all or substantially all of the assets of any such Restricted Subsidiary (which sale, exchange or transfer is not prohibited by this Indenture), (ii) the release or discharge of the Indebtedness that resulted in the creation of such guarantee (except a discharge or release by or as a result of payment under such guarantee), or (iii) the designation of such Restricted Subsidiary as an Unrestricted Subsidiary in accordance with the terms of this Indenture.

SECTION 4.17. Provision of Reports.

(a) Whether or not required by the rules and regulations of the Commission, so long as any Notes are outstanding, the Issuer will furnish to the Holders within the time periods specified in the Commission's rules and regulations:

(1) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Issuer were required to file such Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" that describes the financial condition and results of operations of the Issuer and its Subsidiaries, and, with respect to the annual information only, a report thereon by the Issuer's independent certified public accountants, as applicable; and

(2) all reports that would be required to be filed with the Commission on Form 8-K if the Issuer were required to file such reports.

(b) In addition, following the consummation of the exchange offer contemplated by the Registration Rights Agreement, whether or not required by the rules and regulations of the Commission, the Issuer will file a copy of all such information and reports with the Commission for public availability within the time periods specified in the Commission's rules and regulations (unless the Commission will not accept such a filing) and make such information available to securities analysts and prospective investors upon request.

(c) In addition, the Issuer has agreed that, if it is not subject to and in compliance with the informational requirements of Section 13 or 15(d) of the Exchange Act at any time while the Notes constitute "restricted securities" within the meaning of the Securities Act, it will furnish to Holders and beneficial owners of the Notes and to prospective purchasers designated by such Holders, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to permit compliance with Rule 144A in connection with resales of the Notes.

The Trustee shall not be under a duty to review or evaluate any report or information delivered to the Trustee pursuant to the provisions of this Section 4.17 for the purposes of making such reports available to it and to the Holders of notes who may request such information. Delivery of such reports, information and documents to the Trustee as may be required under this Section 4.17 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 Issuer's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on an Officers' Certificate).

SECTION 4.18. Payments for Consents.

Neither the Issuer nor any of its Subsidiaries shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid or agreed to be paid to all Holders which so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement.

SECTION 4.19. Limitation on Sale or Issuance of Preferred Stock of Restricted Subsidiaries.

(1) the Issuer shall be the continuing Person, or the Person, if other than the Issuer, formed by such consolidation or into which the Issuer is merged, or to which the properties and assets of the Issuer, or of the Issuer and its Subsidiaries on a consolidated basis, substantially as an entirety, are transferred shall be a Person organized and existing under the laws of the United States or any state thereof or the District of Columbia (provided that if such Person is not a corporation, such Person shall be required to cause a Subsidiary of such Person that is a corporation to be a co-obligor under the Notes) and shall expressly assume, by an indenture supplemental to this Indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Issuer under the Notes and this Indenture, and this Indenture remains in full force and effect;

(2) immediately before and immediately after giving effect to such transaction, no Event of Default and no Default shall have occurred and be continuing;

(3) the Person which is formed by or survives such consolidation or merger or to which such assets are transferred (the "surviving entity"), after giving pro forma effect to such transaction, could incur $1.00 of additional Indebtedness pursuant to the Consolidated Cash Flow Coverage Ratio test set forth in clause (A) of Section 4.10(a); and

(4) immediately after giving effect to such transaction on a pro forma basis, the Consolidated Net Worth of the surviving entity shall be equal to or greater than the Consolidated Net Worth of the Issuer immediately before such transaction.

Upon any consolidation or merger, or any transfer of all or substantially all of the assets of the Issuer and its Subsidiaries on a consolidated basis, in accordance with the preceding paragraph, the successor Person formed by such consolidation or into which the Issuer is merged or the successor Person to which such transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Issuer under this Indenture with the same effect as if such successor Person had been named as the Issuer in this Indenture, and when a successor Person assumes all the obligations of its predecessor under this Indenture or the Notes, the predecessor shall be released from those obligations; provided, however, that in the case of a transfer by lease, the predecessor shall not be released from the payment of the principal of, premium, if any, interest on the Notes.

ARTICLE VI
DEFAULT AND REMEDIES

SECTION 6.01. Events of Default.

Each of the following constitutes an "Event of Default":

(1) the Issuer defaults in the payment, when due and payable, of (i) interest on any Note and the default continues for a period of 30 days, or (ii) principal or Accreted Value of or premium, if any, on any Notes when the same becomes due and payable at maturity, by acceleration, on the Redemption Date, on the Change of Control Payment Date, on any payment date respecting an Excess Proceeds Offer or otherwise;

(2) the Issuer fails to comply with any of the provisions set forth under Section 5.01;

(3) the Issuer fails to comply with any of its covenants or agreements in the Notes or this Indenture (other than those referred to in clause (1) or (2) above) and such failure continues for the period and after receipt by the Issuer of the notice specified below;

(4) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Issuer or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Issuer or any of its Restricted Subsidiaries), whether such indebtedness or guarantee is now existing or hereafter created, if such default shall constitute a failure to pay any portion of the principal of such indebtedness when due and payable or if as a result of such default the maturity of such indebtedness has been accelerated prior to its stated maturity and, in either case, the principal amount of such indebtedness, together with the principal amount of any other such indebtedness for money borrowed which has not been paid when due and payable or the maturity of which has been accelerated as a result of such default, aggregates $15 million or more;

(5) the Issuer or any of its Significant Subsidiaries that is a Restricted Subsidiary (or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary) pursuant to or within the meaning of any bankruptcy law:

(A) commences a voluntary case or proceeding;

(B) consents to the entry of an order for relief against it in an involuntary case or proceeding;

(D) makes a general assignment for the benefit of its creditors; or

(E) admits in writing its inability to pay its debts generally as they become due;

(6) a court of competent jurisdiction enters an order or decree under any bankruptcy law that:

(A) is for relief against the Issuer or any of its Significant Subsidiaries that is a Restricted Subsidiary (or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary) in an involuntary case or proceeding;

(B) appoints a custodian of the Issuer or any of its Significant Subsidiaries that is a Restricted Subsidiary (or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary) for all or substantially all of its properties; or

(C) orders the liquidation of the Issuer or any of its Significant Subsidiaries that is a Restricted Subsidiary (or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary),

and such order or decree with respect to clause (A), (B) or (C) remains unstayed and in effect for 60 days; or

(7) final judgments for the payment of money which in the aggregate exceed $15 million shall be rendered against the Issuer or any of its Restricted Subsidiaries by a court and shall remain unstayed or undischarged for a period of 60 days.

A Default specified in Section 6.01(3) above is not an Event of Default until the Trustee notifies the Issuer, or the Holders of at least 25% in aggregate principal amount at maturity of the Notes at the time outstanding notify the Issuer and the Trustee, of the Default and the Issuer does not cure such Default within 30 days after receipt of such notice. Any such notice must specify the Default, demand that is be remedied and state that such notice is a "Notice of Default."

SECTION 6.02. Acceleration.

If an Event of Default specified in Section 6.01(5) or (6) above occurs and is continuing, then all unpaid Accreted Value of, and premium, if any, and accrued and unpaid interest, if any, on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of each Trustee or any Holder.

If any Event of Default (other than an Event of Default specified in Section 6.01 (5) or (6)) occurs and is continuing, the Trustee or the Holders of at least 25% of the principal amount at maturity of the Notes then outstanding, by written notice to the Issuer (and to the Trustee if such notice is given by such Holders), may, and such Trustee at the request of such Holders shall, declare all unpaid Accreted Value, premium, if any, accrued interest on the Notes to be due and payable immediately.

In the case of any Event of Default (other than as a result of the failure to comply with Section 4.09) occurring by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Issuer with the intention of avoiding payment of the premium which the Issuer would have to pay if the Issuer then had elected to redeem the Notes, an equivalent premium shall also become and be immediately due and payable at such time as the principal and interest on the Notes become due and payable pursuant to this Section 6.02 to the extent permitted by law, anything in this Indenture or in the Notes contained to the contrary notwithstanding.

In the case of an Event of Default as a result of a failure to comply with Section 4.09 occurring by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Issuer with the intention of avoiding payment of the premium which the Issuer would have to pay pursuant to Section 4.09, such premium shall also become and be immediately due and payable at such time as the principal and interest on the Notes become due and payable pursuant to this Section 6.02 to the extent permitted by law, anything in this Indenture or in the Notes contained to the contrary notwithstanding.

At any time after a declaration of acceleration (except an acceleration due to default in payment of Accreted Value, premium, if any, accrued interest on the Notes) with respect to the Notes as described in the four preceding paragraphs, the holders of a majority in principal amount at maturity of the Notes may rescind and cancel such declaration and its consequences, if all existing Events of Default have been cured or waived, except non-payment of the Accreted Value, premium, if any, accrued interest on the Notes that have become due solely because of the acceleration.

SECTION 6.03. Other Remedies.

(a) If a Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of Accreted Value, premium, if any, or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

(b) The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Noteholder in exercising any right or remedy accruing upon a Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law.

(c) Holders may not enforce this Indenture or the Notes except as provided in this Indenture and under the TIA. Subject to the provisions of this Indenture relating to the duties of the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under this Indenture at the request, order or direction of any of the Holders, unless such Holders have offered to the Trustee reasonable indemnity. Subject to all provisions of this Indenture and applicable law, the Holders of a majority in aggregate principal amount at maturity of the then outstanding Notes issued under this Indenture 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.

SECTION 6.04. Waiver of Defaults.

Provided the Notes are not then due and payable by reason of a declaration of acceleration, the Holders of a majority in aggregate principal amount at maturity of Notes at the time outstanding may on behalf of the Holders of all the Notes waive any Default with respect to such Notes and its consequences by providing written notice thereof to the Issuer and the Trustee, except a Default (1) in the payment of Accreted Value of, premium, if any, or interest, if any, on any Note or (2) in respect of a covenant or provision hereof which under this Indenture cannot be modified or amended without the consent of the Holder of each outstanding Note affected. In the case of any such waiver, the Issuer, the Trustee and the Holders will be restored to their former positions and rights under this Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or impair any right consequent thereto.

SECTION 6.05. Control by Majority.

The Holders of not less than a majority in principal amount at maturity of the outstanding Notes may 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 it. Subject to Section 7.01, however, the Trustee may refuse to follow any direction that conflicts with any law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Noteholder, or that may involve the Trustee in personal liability; provided that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

In the event the Trustee takes any action or follows any direction pursuant to this Indenture, the Trustee shall be entitled to indemnification against any loss or expense caused by taking such action or following such direction.

SECTION 6.06. Limitation on Suits.

A Holder may not pursue any remedy with respect to this Indenture or the Notes unless:

(1) the Holder gives to the Trustee written notice of a continuing Event of Default;

(2) the Holder or Holders of at least 25% in principal amount at maturity of the outstanding Notes make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer and provide to the Trustee reasonable indemnity or security against any loss, liability or expense satisfactory to the Trustee;

(4) the Trustee does not comply with the request within 30 days after receipt of the request and the offer of indemnity and security; and

(5) during such 30-day period the Holder or Holders of a majority in principal amount at maturity of the outstanding Notes do not give the Trustee a direction which, in the opinion of the Trustee, is inconsistent with the request.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over such other Holder.

SECTION 6.07. Rights of Holders To Receive Payment.

Within 60 days after each May 15, beginning with May 15, 2004, the Trustee shall, to the extent that any of the events described in TIA § 313(a) occurred within the previous twelve months, but not otherwise, mail to each Holder a brief report dated as of such date that complies with TIA § 313(a).

The Issuer shall notify the Trustee if the Notes become listed on any securities exchange or of any delisting thereof and the Trustee shall comply with TIA § 313(d).

SECTION 7.07. Compensation and Indemnity.

The Issuer shall pay to the Trustee from time to time such compensation as the Issuer and the Trustee shall from time to time agree in writing for its services hereunder. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee upon request for all reasonable disbursements, expenses and advances (including reasonable fees and expenses of counsel) incurred or made by it in addition to the compensation for its services, except any such disbursements, expenses and advances as may be attributable to the Trustee's negligence, bad faith or willful misconduct.

The Trustee and its agents, employees, officers, stockholders and directors subject to the claim may have separate counsel and the Issuer shall pay the reasonable fees and expenses of such counsel; provided, however, that the Issuer will not be required to pay such fees and expenses if, subject to the approval of the Trustee (which approval shall not be unreasonably withheld), it assumes the Trustee's defense and there is no conflict of interest between the Issuer and the Trustee and its agents, employees, officers, stockholders and directors subject to the claim in connection with such defense as reasonably determined by the Trustee. The Issuer need not pay for any settlement made without its written consent. The Issuer need not reimburse any expense or indemnify against any loss or liability to the extent incurred by the Trustee through its negligence, bad faith or willful misconduct.

To secure the Issuer's payment obligations in this Section 7.07, the Trustee shall have a senior lien prior to the Notes against all money or property held or collected by the Trustee, in its capacity as Trustee.

Without prejudice to its rights hereunder, when the Trustee incurs expenses or renders services after a Default specified in Section 6.01(5) or (6) occurs, such expenses and the compensation for such services (including the fees and expenses of its agent and counsel) shall constitute expenses of administration under the Bankruptcy Law.

SECTION 7.08. Replacement of Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Immediately after that, the retiring Trustee shall transfer, after payment of all sums then owing to the Trustee pursuant to Section 7.07, all property held by it as Trustee to the successor Trustee, subject to the Lien provided in Section 7.07, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail notice of its succession to each Holder. A resignation of the Trustee shall not be effective until a successor trustee delivers a written acceptance of its appointment in accordance with this Section 7.08.

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of at least 10% in principal amount at maturity of the outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee at the expense of the Issuer.

If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(2) make any change to the Stated Maturity or time for payment of the principal or Accreted Value of, premium, if any, interest on the Notes or any Redemption Price thereof, or impair the right to institute suit for the enforcement of any such payment or make any Note payable in money or securities other than that stated in the Note;

(3) change the method of calculation of Accreted Value;

(4) waive a default in the payment of principal or Accreted Value of, premium, if any, interest on any Notes;

(5) make any change in Section 4.09 or Section 4.13; or

(6) make any change to this Section 9.02.

(c) It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment, supplement or waiver but it shall be sufficient if such consent approves the substance thereof.

(d) After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

SECTION 9.03. Compliance with TIA.

From the date on which this Indenture is qualified under the TIA, every amendment, waiver or supplement of this Indenture or the Notes shall comply with the TIA as then in effect.

SECTION 9.04. Revocation and Effect of Consents.

(a) Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to his Note or portion of his Note by notice to the Trustee or the Issuer received before the date on which the Trustee receives an Officers' Certificate certifying that the Holders of the requisite principal amount at maturity of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver.

(b) The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver which record date shall be at least 30 days prior to the first solicitation of such consent. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Noteholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date. The Issuer shall inform the Trustee in writing of the fixed record date if applicable.

(c) After an amendment, supplement or waiver becomes effective, it shall bind every Noteholder, unless it makes a change described in any of clauses (1) through (6) of Section 9.02(b), in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note; provided that any such waiver shall not impair or affect the right of any Holder to receive payment of principal of and interest on a Note, on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates without the consent of such Holder.

SECTION 9.05. Notation on or Exchange of Notes.

If an amendment, supplement or waiver changes the terms of a Note, the Issuer may require the Holder of the Note to deliver it to the Trustee. The Issuer shall provide the Trustee with an appropriate notation on the Note about the changed terms and cause the Trustee to return it to the Holder at the Issuer's expense. Alternatively, if the Issuer or the Trustee so determines, the Issuer in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.06. Trustee To Sign Amendments, Etc.

The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article IX; provided that the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee's own rights, duties or immunities under this Indenture. The Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel and an Officers' Certificate each stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article IX is authorized or permitted by this Indenture and constituted the legal, valid and binding obligations of the Issuer enforceable in accordance with its terms. Such Opinion of Counsel shall be at the expense of the Issuer.
