Section 2.06. Transfer Restrictions. The following provisions shall apply only to Global Notes:

Redemption Of The Notes

Section 3.01. Optional Redemption by Company. The Notes may be redeemed at the option of the Company on the terms and conditions set forth in the form of Note set forth as Exhibit A.

Section 3.02. Change of Control Repurchase Event. If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem the Notes as described in Section 3.01, the Company will make an offer to each Holder to repurchase all or any part (in integral multiples of $1,000) of that Xxxxxx’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to the date of purchase. Within 30 days following any Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Company will mail a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase the Notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice.

The Company will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of this Note, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions of this Note by virtue of such conflict.

On the Change of Control Repurchase Event payment date, the Company will, to the extent lawful:

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Company’s offer;

(ii) deposit with the paying agent an amount equal to the aggregate purchase price in respect of all Notes or portions of Notes properly tendered; and

(iii) deliver or cause to be delivered to the Trustee the Notes properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of Notes being purchased by the Company.

The Paying Agent will promptly mail its check or otherwise cause to be paid to each holder of Notes properly tendered the purchase price for the Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new Note equal in principal amount to any unpurchased portion of 

any Notes surrendered; provided that each new Note will be in a principal amount of $1,000 or an integral multiple of $1,000.

The Company will not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Notes properly tendered and not withdrawn under its offer.

As used herein:

"below investment grade rating event" means the Notes are rated below investment grade by both rating agencies on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended so long as the rating of the Notes is under publicly announced consideration for possible downgrade by either of the rating agencies); provided, that, a below investment grade rating event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect to a particular Change of Control (and thus shall not be deemed a below investment grade rating event for purposes of the definition of Change of Control Repurchase Event hereunder) if the rating agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the below investment grade rating event).

"Change of Control" means the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any "person" (as that term is used in Section 13(d)(3) of the Exchange Act) becomes the beneficial owner, directly or indirectly, of more than 50% of the Company’s voting stock measured by voting power rather than number of shares.

"Change of Control Repurchase Event" means the occurrence of both a Change of Control and a below investment grade rating event.

"investment grade" means a rating of Baa3 of better by Xxxxx’x (or its equivalent under any successor rating categories of Xxxxx’x); a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P); and the equivalent investment grade credit rating from any additional rating agency or rating agencies selected by the Company.

"Xxxxx’x" means Xxxxx’x Investors Service Inc.

"rating agency" means (1) each of Xxxxx’x and S&P; and (2) if either of Xxxxx’x or S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of the Company’s control, a "nationally recognized statistical rating organization" within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act, selected by the Company (as certified by a resolution of the Company’s board of directors) as a replacement agency for Xxxxx’x or S&P, or both, as the case may be.

"S&P" means Standard & Poor’s Ratings Services, a division of XxXxxx-Xxxx, Inc.

"voting stock" of any specified "person" (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

Section 5.04. Separability.

In case any provision contained in this Supplemental Indenture or in the Notes shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Supplemental Indenture or of the Notes, but this Supplemental Indenture and the Notes shall be construed as if such invalid or illegal or unenforceable provision had never been contained herein or therein.

Section 5.05. Counterparts.

This Supplemental Indenture may be executed in any number of counterparts each of which shall be an original; but such counterparts shall together constitute but one and the same instrument.

(ii) as determined by the Independent Investment Banker, the sum of the present values of the principal amount of and remaining scheduled payments of interest on the Notes to be redeemed (not

As provided in the Indenture and subject to certain limitations herein and therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes of different authorized denominations, as requested by the Holders surrendering the same.

This Note is a Global Security.
