“ARTICLE 18

Special Repurchase of Notes at Option of Holders

Section 18.01. Special Repurchase at Option of Holders. (a) Each Holder shall have the right at any time following the date of the consummation of the Transactions until the Maturity Date, at such Holder’s option, to require the Company to repurchase (any such repurchase, a “Special Repurchase”), on one or more occasions, for cash all of such Holder’s Notes, or any portion thereof that is equal to $1,000 or a multiple thereof, on the date (the “Special Repurchase Date”) that is 5 Business Days following the date of receipt by the Company of a Special Repurchase Notice delivered in accordance with Section 18.01(b) at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Special Repurchase Date (the “Special Repurchase Price”), unless the Special Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such Regular Record Date, and the Special

Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 18.

(b)     Repurchases of Notes under this Section 18.01 shall be made, at the option of the Holder thereof, upon:

(i)     the delivery to the Company and the Paying Agent by a Holder of a duly completed notice (the “Special Repurchase Notice”) in the form attached to the Indenture as Exhibit B, if the Notes are Physical Notes, and in compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in each case within the 10 Business Day period immediately after the last day of the 10 consecutive Trading Day period related to the relevant Special Repurchase Event; and

(ii)     delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the Special Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery being a condition to receipt by the Holder of the Special Repurchase Price therefor, together with such other documentation the Company may deem necessary in connection with any such Special Repurchase.

The Special Repurchase Notice in respect of any Notes to be repurchased shall state:

(i)          that a Special Repurchase Event has occurred (and shall include evidence of the occurrence of such Special Repurchase Event reasonably satisfactory to the Company);

(ii)          in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;

(iii)          the portion of the principal amount of Notes to be repurchased, which if repurchased in part, must be $1,000 or a multiple thereof; and

(iv)          that the Notes are to be repurchased by the Company pursuant to Article 18 of this Indenture;

provided, however, that if the Notes are Global Notes, the Special Repurchase Notice must also comply with appropriate Depositary procedures.

18.02. Deposit of Special Repurchase Price. (a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04) on or prior to 11:00 a.m., New York City time, on the relevant Special Repurchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the Special Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment

for Notes surrendered for repurchase will be made on the later of (i) the Special Repurchase Date (provided the Holder has satisfied the conditions in Section 18.01) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 18.01 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the sum of (1) the Special Repurchase Price and (2) if applicable, accrued and unpaid interest, in each case, in respect of all of the Notes to be so repurchased on such Special Repurchase Date.

(b)     If by 11:00 a.m. New York City time, on the Special Repurchase Date, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Special Repurchase Date, then, with respect to the Notes that have been properly surrendered for repurchase, (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Special Repurchase Price and, if applicable, accrued and unpaid interest).

(c)     Upon surrender of a Note that is to be repurchased in part pursuant to Section 18.01, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered.

18.03. Certain Definitions in Respect of the Special Repurchase at Option of Holders. For purposes of this Article 18:

A “Special Repurchase Event” shall have occurred if, on at least 3 Trading Days during any 10 consecutive Trading Day period following the date of the consummation of the Transactions, the Notes Trading Price is less than 100% of the principal amount thereof.

The “Notes Trading Price” means, on any date of determination, the secondary market bid quotation obtained by any Holder delivering a Special Repurchase Notice for at least $1,000,000 principal amount of Notes on such determination date from an independent nationally recognized securities dealer.”

(d)     The Original Indenture is hereby amended to insert a new Exhibit B in the form attached as “Exhibit B” hereto and the corresponding change shall be made to the Original Indenture’s Table of Contents.
