(a) A Global Note deposited with the Depositary or with the Custodian may be transferred to the beneficial owners thereof in the form of Definitive Notes in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, only if such transfer complies with Section 2.05 below and (i) the Depositary (A) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Note, (B) defaults in the performance of its duties as Depositary, or (C) has ceased to be a clearing agency registered under the Exchange Act at a time when the Depositary is required to be so registered to act as depositary, in each case, unless the Company has approved a successor Depositary within 90 days after receipt of such notice or after it has become aware of such default or cessation or (ii) the Company in its sole discretion determines, subject to the procedures of the Depositary, that such Global Note will be so exchangeable or transferable.

-6-

(b) Any Global Note that is transferable to the beneficial owners thereof pursuant to this Section 2.04 shall be surrendered by the Depositary to the Trustee, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Note, an equal aggregate principal amount of Definitive Notes of authorized denominations. Any portion of a Global Note transferred pursuant to this Section 2.04 shall be executed, authenticated and delivered only in denominations of $2,000 and integral multiples of $1,000 in excess thereof and registered in such names as the Depositary shall direct.

(c) At such time as all beneficial interests in a Global Note have either been exchanged for Definitive Notes, transferred in exchange for an interest in another Global Note, redeemed, repurchased or canceled, such Global Note shall be returned by the Depositary to the Trustee for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for Definitive Notes, transferred in exchange for an interest in another Global Note, redeemed, repurchased or canceled, the principal amount of Notes represented by such Global Note shall be appropriately reduced or increased, and an adjustment shall be made on the books and records of the Trustee (if it is then the Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Custodian, to reflect such reduction or increase.

the Trustee shall cancel such Definitive Note and cause, or direct the Custodian to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Custodian, the aggregate principal amount of Notes represented by the Global Note to be increased by the aggregate principal amount of the Definitive Note to be exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Global Note equal to the principal amount of the Definitive Note so canceled. If the applicable Global Note is not then outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officer’s Certificate, a new applicable Global Note in the appropriate principal amount.

(ii) If the proposed transfer is a transfer of a beneficial interest in one Global Note to a beneficial interest in another Global Note, the Security Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Security Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Note from which such interest is being transferred.

(iii) Notwithstanding any other provisions of this Section 2.05, a Global Note may not be transferred except as a whole and not in part if the transfer is by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

(b) Prior to the Par Call Date, the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (i) (A) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points less (B) interest accrued to the Redemption Date, and (ii) 100% of the principal amount of the Notes to be redeemed, plus, in the case of each of clauses (i) and (ii), accrued and unpaid interest thereon to the Redemption Date.

(c) On or after the Par Call Date, the Company may redeem the Notes at the its option, in whole or in part, at any time and from time to time at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest thereon to the Redemption Date for such Notes.

(d) On and after the Redemption Date, interest will cease to accrue on such Notes or any portion thereof called for redemption, unless the Company defaults in the payment of the Redemption Price and accrued interest, if any.

No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by the Depositary, the redemption of the Notes shall be done in accordance with the Applicable Procedures.

Notwithstanding the foregoing, the Company may, without securing the Notes, incur Liens existing on such capital stock before the acquisition thereof by it or by any Subsidiary or prior to the date that such Subsidiary becomes a Material Insurance Subsidiary so long as (1) such Lien was in existence prior to, and is not created in contemplation of or in connection with, such acquisition or such Subsidiary becoming a Material Insurance Subsidiary, as the case may be, (2) such Lien will not apply to capital stock of any other Material Insurance Subsidiary and (3) such Lien will secure only those obligations which it secures on the date of such acquisition or the date that such Subsidiary becomes a Material Insurance Subsidiary, as the case may be, and extensions, renewals and replacements of the foregoing Liens that do not increase the outstanding principal amount secured by such Liens and do not extend to capital stock of any other Material Insurance Subsidiary.

(b) Neither the Company nor any of the Domestic Subsidiaries will be permitted to issue, sell, transfer or dispose of capital stock of a Material Insurance Subsidiary, except to the Company or one of its Subsidiaries, unless (1) the Company or the applicable Domestic Subsidiary or Domestic Subsidiaries dispose of the entire capital stock of the Material Insurance Subsidiary at the same time for cash or property which, in the opinion of the Board of Directors, is at least equal to the fair market value of the capital stock or (2) the Company or the applicable Domestic Subsidiary or Domestic Subsidiaries sell, transfer or otherwise dispose of any capital stock of a Material Insurance Subsidiary for at least fair market value (in the opinion of the Board of Directors) and, after giving effect thereto, the Company and its Subsidiaries would own more than 80% of the issued and outstanding voting stock of such Material Insurance Subsidiary.

-11-

Notwithstanding the foregoing, the immediately preceding paragraph shall not prohibit (a) for the avoidance of doubt, the incurrence or existence of Liens on capital stock of any Subsidiaries, or (b) the issuance, sale, transfer or disposition of capital stock of a Material Insurance Subsidiary by the Company or any of its Domestic Subsidiaries:
