Except under the limited circumstances described below, Series A Senior Notes represented by such Global Securities will not be exchangeable for, and will not otherwise be issuable as, Series A Senior Notes in definitive form. The Global Securities described above may not be transferred except 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 to a successor Depositary or its nominee.

Owners of beneficial interests in such a Global Security will not be considered the Holders thereof for any purpose under the Indenture, and no Global Security representing a Series A Senior Note shall be exchangeable, except for another Global Security of like denomination and tenor to be registered in the name of the Depositary or its nominee or to a successor Depositary or its nominee or except as described below. The rights of Holders of such Global Security shall be exercised only through the Depositary.

A Global Security shall be exchangeable for Series A Senior Notes registered in the names of persons other than the Depositary or its nominee only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as a Depositary for such Global Security and no successor Depositary shall have been appointed by the Company within 90 days of receipt by the Company of such notification, or if at any time the Depositary ceases 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 such Depositary and no successor Depositary shall have been appointed by the Company within 90 days after it becomes aware of such cessation, or (ii) the Company in its sole discretion determines that such Global Security shall be so exchangeable, in which case Series A Senior Notes in definitive form will be printed and delivered to the Depositary. Any Global

6

Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Series A Senior Notes registered in such names as the Depositary shall direct.

SECTION 106. Redemption. The Series A Senior Notes are redeemable, in whole or in part, at any time, and at the option of the Company, at a Redemption Price equal to the greater of:

(i) 100% of the principal amount of Series A Senior Notes then Outstanding to be so redeemed, or

(ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 15 basis points, as calculated by an Independent Investment Banker,

plus, in either of the above cases, accrued and unpaid interest thereon to the Redemption Date.

Unless the Company defaults in the payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Series A Senior Notes or portions thereof called for redemption.

The Adjusted Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.

In the event of the redemption of the Series A Senior Notes in part only, a new Series A Senior Note or Notes for the unredeemed portion will be issued in the name or names of the Holders thereof upon surrender thereof.

The Company shall notify the Series Trustee of the Redemption Price promptly after the calculation thereof and the Series Trustee shall have no responsibility for such calculation.

SECTION 107. Sinking Fund. The Series A Senior Notes shall not have a sinking fund.

SECTION 108. Additional Interest.

SECTION 109. Paying Agent. The Series Trustee shall initially serve as Paying Agent with respect to the Series A Senior Notes, with the Place of Payment initially being the Corporate Trust Office of the Series Trustee.

7

SECTION 110. Limitation on Liens. The Company will not, while any of the Series A Senior Notes remain Outstanding, create, or suffer to be created or to exist, any Lien upon any Principal Property of the Company or upon any shares of stock of any Material Subsidiary of the Company, whether such Principal Property is, or shares of stock are, now owned or hereafter acquired, to secure any indebtedness for borrowed money of the Company, unless it shall make effective provision whereby the Series A Senior Notes then Outstanding shall be secured by such Lien equally and ratably with any and all indebtedness for borrowed money thereby secured so long as any such indebtedness shall be so secured; provided, however, that nothing in this Section shall be construed to prevent the Company from creating, or from suffering to be created or to exist, any Liens, or any agreements, with respect to:
