While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money.

          If any such exchange or transfer from a Definitive Note to a beneficial interest is effected pursuant to subparagraphs (ii)(B), (ii)(D) or (iii) above at a time when an Unrestricted Global Note has not yet been issued, the Company shall issue and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the principal amount of Definitive Notes so transferred.

          (iii) Unrestricted Definitive Notes to Unrestricted Definitive Notes . A Holder of Unrestricted Definitive Notes may transfer such Notes to a Person who takes delivery thereof in the form of an Unrestricted Definitive Note. Upon receipt of a request to register such a transfer, the Registrar shall register the Unrestricted Definitive Notes pursuant to the instructions from the Holder thereof.

          (f) Exchange Offer . Upon the occurrence of the Exchange Offer in accordance with the Registration Rights Agreement, the Company shall issue and, upon receipt of an Authentication Order in accordance with Section 2.02, the Trustee shall authenticate (i) one or more Unrestricted Global Notes in an aggregate principal amount equal to the principal amount of the beneficial interests in the Restricted Global Notes tendered for acceptance by Persons that certify in the applicable Letters of Transmittal that (x) they are not broker-dealers, (y) they are not participating in a distribution of the Exchange Notes and (z) they are not affiliates (as defined in Rule 144) of the Company, and accepted for exchange in the Exchange Offer and (ii) Definitive Notes in an aggregate principal amount equal to the principal amount of the Restricted Definitive Notes accepted for exchange in the Exchange Offer.

          (g) Automatic Exchange from Restricted Global Note to Unrestricted Global Note . On the Automatic Exchange Date, beneficial interests in a Global Note bearing a legend pursuant to Section 2.06(i)(i) and subject to the restrictions on transfer imposed thereby will be automatically exchanged into beneficial interests in a freely transferable Unrestricted Global Note, which shall not bear such legend without any action required by or on behalf of the Holder (the “ Automatic Exchange ”). In order to effect the Automatic Exchange:

     (i) the Company shall at least eight Business Days but not more than 15 Business Days prior to the Automatic Exchange Date, deliver a notice of Automatic Exchange (an “ Automatic Exchange Notice ”) to the Trustee;

     (ii) within three Business Days after its receipt of the Automatic Exchange Notice, the Trustee shall deliver, in the Company’s name and at its expense, the Automatic Exchange Notice to each Holder at such Holder’s address appearing in the register of the Notes kept by the Registrar; and

     (iii) the Company shall at least one Business Day prior to the Automatic Exchange Date, deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel to the Company, in form and in substance reasonably satisfactory to the Trustee and upon which the Trustee may rely conclusively, without liability, to the effect that such transfer of beneficial interests to the Unrestricted Global Notes shall be in compliance with the Securities Act.

The Automatic Exchange Notice shall identify the Notes subject to the Automatic Exchange and shall state: (1) the Automatic Exchange Date; (2) that the Automatic Exchange shall occur pursuant to this Section 2.06(g) of the Indenture; (3) the “CUSIP” number of the Restricted Global Notes from which such Holders’ beneficial interests will be transferred and (4) the “CUSIP” number of the Unrestricted Global Securities into which such Holders’ beneficial interests will be transferred. On the Automatic Exchange Date, the Automatic Exchange shall occur and the Registrar shall endorse Schedule A to the relevant Notes and reflect on its books and records the date of such transfer and a decrease and increase, respectively, in the principal amount of the applicable Restricted Global Note(s) and the Unrestricted Global Notes, respectively, equal to the principal amount of beneficial interests transferred. If, following any such transfer pursuant to this Section 2.06(g), the principal amount of the relevant Restricted Global Note is zero, then the relevant Restricted Global Note shall be cancelled. In no event will the failure of the Company to provide any notice set forth in this Section 2.06(g) or of the Trustee to effect the Automatic Exchange constitute a failure by the Company to comply with any of its covenants or agreements set forth in this Indenture for purposes of Article 6 hereof or otherwise.

          (h) Transfers of Securities Held by Affiliates . Any certificate (i) evidencing a Note that has been transferred to an Affiliate of the Company within one year after the Issue Date, as evidenced by a notation on the assignment form for such transfer or in the representation letter delivered in respect thereof or (ii) evidencing a Note that has been acquired from an Affiliate (other than by an Affiliate) in a transaction or a chain of transactions not involving any public offering, shall, until one year after the last date on which either the Company or any Affiliate of the Company was an owner of such Note, in each case, be in certificated form and subject to the restrictions on transfer and bear a legend pursuant to Section 2.06(i)(i). The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Sections 2.03 and 2.05 of this Indenture. The Company, at its sole cost and expense, 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 written notice to the Registrar.

          (i) Legends . The following legends shall appear on the face of all Global Notes and Definitive Notes issued under this Indenture unless specifically stated otherwise in the applicable provisions of this Indenture.

               (i)  Private Placement Legend .

          (A) Except as permitted by subparagraph (B) below, each Global Note and each Definitive Note (and all Notes issued in exchange therefor or substitution thereof) shall bear the legend in substantially the following form:

“THIS NOTE HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS, EXCEPT AS SET FORTH BELOW. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (a) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) (A “QIB”) OR (b) IT IS NOT A U.S. PERSON AND IS ACQUIRING THE NOTE EVIDENCED HEREBY IN AN OFFSHORE TRANSACTION, (2) AGREES THAT IT WILL NOT, WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY, RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (a) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (b) INSIDE THE UNITED STATES TO A QIB IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (c) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (d) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (e) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.”

     (B) Notwithstanding the foregoing, any Global Note or Definitive Note issued pursuant to subparagraphs (b)(iv), (c)(ii), (c)(iii), (d)(ii), (d)(iii), (e)(ii), (e)(iii), (f) or (g) to this Section 2.06 (and all Notes issued in exchange therefor or substitution thereof) shall not bear the Private Placement Legend.

          (ii)  Global Note Legend . Each Global Note shall bear a legend in substantially the following form:

“THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.07 OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.06(a) OF THE INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.”

          (j)  Cancellation and/or Adjustment of Global Notes . At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for

Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

          (k)  General Provisions Relating to Transfers and Exchanges .

          (i) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon the Company’s order or at the Registrar’s request.

          (ii) No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof).

          (iii) The Registrar shall not be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

          (iv) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

          (v) The Company shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding Interest Payment Date.

          (vi) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary.

          (vii) The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof.

          (viii) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile.

               Section 2.07. Replacement Notes .

          If a mutilated Note is surrendered to the Registrar or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate, upon receipt of an Authentication Order, a replacement Security. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Note is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Note.

          Every replacement Note is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

               Section 2.08. Outstanding Notes .

          The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 3.07(b) hereof.

          If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a bona fide purchaser.

          If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

          If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

               Section 2.09. Treasury Notes .

          In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, 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 so disregarded.

               Section 2.10. Temporary Notes .

          Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary

Notes shall be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes.

          Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

               Section 2.11. Cancellation .

          The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and dispose of such Notes in its customary manner (subject to the record retention requirements of the Exchange Act) all Notes surrendered for registration of transfer, exchange, payment or cancellation and deliver a certificate of such disposition to the Company upon request, unless the Company directs the Trustee to deliver canceled Notes to the Company. Certification of the disposition of all canceled Notes shall be delivered to the Company upon request. The Company may not issue new Notes to replace Notes that it has redeemed or paid or that have been delivered to the Trustee for cancellation.

               Section 2.12. Defaulted Interest .

          If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. 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. The Company shall fix or cause to be fixed each such special record date and payment date, provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

               Section 2.13. CUSIP Numbers .

          The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee of any change in the CUSIP numbers.

               Section 2.14. Issuance of Additional Notes .

          The Company shall be entitled, subject to its compliance with Section 4.09, to issue Additional Notes under this Indenture which shall have identical terms as the Initial Notes issued on the Issue Date, other than with respect to the date of issuance and issue price. The Initial Notes issued on the Issue Date, any Additional Notes and all Exchange Notes or Private Exchange Notes issued in exchange therefor shall be treated as a single class for all purposes under this Indenture.

          With respect to any Additional Notes, the Company shall set forth in a resolution of the Board of Directors and an Officers’ Certificate, a copy of each which shall be delivered to the Trustee, the following information:

     (a) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture;

     (b) the issue price, the issue date and the CUSIP number of such Additional Notes; provided that no Additional Notes may be issued at a price that would cause such Additional Notes to have “original issue discount” within the meaning of Section 1273 of the Code; and

     (c) whether such Additional Notes shall be transfer restricted notes and issued in the form of Initial Notes as set forth in Section 2.02 this Indenture or shall be issued in the form of Exchange Notes.

ARTICLE 3.

REDEMPTION AND PREPAYMENT

               Section 3.01. Notices to Trustee .

          If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee, at least 30 days but not more than 60 days before a redemption date, an Officers’ Certificate setting forth (i) the clause of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the redemption price.

               Section 3.02. Selection of Notes To Be Redeemed .

          If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select the Notes to be redeemed or purchased among the Holders of the Notes in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or in accordance with any other method the Trustee considers appropriate.

          The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in integral multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. No Note may be redeemed in part if such redemption would result in its face value being less than $2,000. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The Trustee shall notify the Company promptly of the Notes or portions of Notes to be redeemed.

               Section 3.03. Notice of Redemption .

          Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at such Holder’s registered address;

provided that in the latter case the Trustee shall be given at least five (5) days
