As provided in the Indenture and subject to certain limitations therein set forth, the Company may at its option redeem the Notes in whole or in part on the Redemption Date.

reason of the making of such payment, by the United States or any taxing authority thereof or therein, will not be less than the amount provided for in the Notes to be then due and payable.

As provided in the Indenture and subject to certain limitations therein set forth, the Notes may be redeemed at the option of the Company in whole if the Company determines that as a result of any change in or amendment to the laws or treaties, or any regulations or rulings promulgated thereunder, of the United States or of any political subdivision or taxing authority thereof or therein affecting taxation, or any proposed change in such laws, treaties or regulations or rulings, or any change in the official application, enforcement or interpretation of such laws, treaties or regulations or filings (including a holding by a court of competent jurisdiction in the United States) or any other action (other than an action predicated on law generally known on or before the date specified in such Note except for proposals before the Congress before such date) taken by any taxing authority or a court of competent jurisdiction in the United States, or the official proposal of any such action, whether or not such action or proposal was taken or made with respect to the Company, (A) the Company has or will become obligated to pay any Additional Amounts referred to in the foregoing paragraph pursuant to the Indenture on the Note or (B) there is a substantial possibility that the Company will be required to pay such Additional Amounts.

As provided in the Indenture and subject to certain limitations therein set forth, in case an Event of Default with respect to the Notes shall have occurred and be continuing, the principal hereof may be declared, and upon such declaration shall become due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

6

The Company may omit to comply with any term, provision or condition set forth in Section 801 of the Indenture, and any such omission with respect to such Section shall not be an Event of Default, in each case with respect to the Notes, provided that the conditions of Section 1009 of the Indenture have been satisfied.

The covenant set forth in Section 1005 of the Indenture shall not apply to the Notes.

Notwithstanding the provisions of Section 401(a)(B) of the Indenture, the Company may satisfy and discharge the entire indebtedness on all the Notes as provided therein only when the Notes are by their terms due and payable within one year.

The Company, the Trustee, and any agent of the Company or of the Trustee may deem and treat the registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment hereof, or on account hereof, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or of the Trustee shall be affected by any notice to the contrary.  All such payments made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, effectually satisfy and discharge liability for moneys payable on this Note.

The Notes are issuable in registered form without coupons in denominations of $1,000 and any multiple of $1,000.  At the option of the holders thereof, either at the office or agency to be designated and maintained by the Company for such purpose in the Borough of Manhattan, The City of New York, pursuant to the provisions of the Indenture or at any of such other offices or agencies as may be designated and maintained by the Company for such purpose pursuant to the provisions of the Indenture, and in the manner and subject to the limitations provided in the Indenture, but without the payment of any service charge, except for any tax or other governmental charges imposed in connection therewith, Notes may be exchanged for an equal aggregate principal amount of Notes of like tenor and of other authorized denominations.

No recourse for the payment of the principal of or the interest on this Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or director as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.
