The Series B Senior Notes will be initially issued in the form of one or more Global Securities registered in the name of the Depositary (which shall be The Depository Trust Company) or its nominee. Except under the limited circumstances described below, Series B Senior Notes represented by such Global Securities will not be exchangeable for, and will not otherwise be issuable as, Series B Senior Notes in definitive form registered in names other than the Depositary or its nominee. 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 B 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 B 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, (ii) the Company in its sole discretion, and subject to the procedures of the Depositary, determines that such Global Security shall be so exchangeable, in which case Series B Senior Notes in definitive form will be printed and delivered to the Depositary, or (iii) an Event of Default has occurred and is continuing with respect to the Series B Senior Notes. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Series B Senior Notes registered in such names as the Depositary shall direct.

SECTION 106. Redemption. The Series B Senior Notes are redeemable, in whole or in part, at any time and from time to time prior to January 15, 2027, at the option of the Company, at a Redemption Price equal to the greater of:

(i) 100% of the principal amount of Series B 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 45 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.

In addition, the Series B Senior Notes are redeemable, in whole or in part at any time and from time to time on or after January 15, 2027, at the option of the Company, at a Redemption Price equal to 100% of the principal amount of the Series B Senior Notes then outstanding to be redeemed, plus accrued and unpaid interest thereon to the Redemption Date.

The Adjusted Treasury Rate shall be calculated no later than the third Business Day preceding 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 B Senior Notes or portions thereof called for redemption.

In the event of the redemption of the Series B Senior Notes in part only, a new Series B 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 Trustee in writing of the Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. The notice of redemption shall be sent in accordance with the terms of the Base Indenture.

SECTION 107. Sinking Fund; Conversion. The Series B Senior Notes shall not have a sinking fund. The Series B Senior Notes are not convertible into or exchangeable for Equity Securities and/or any other securities.

SECTION 108. Additional Interest on Overdue Amounts. Any principal of and installment of interest on the Series B Senior Notes that is overdue shall bear interest at the rate of 3.60% (to the extent that the payment of such interest shall be legally enforceable), from the dates such amounts are due until they are paid or made available for payment, and such interest shall be payable on demand.
