The Senior Notes may be issued from time to time upon written order of the Company for the authentication and delivery of Senior Notes pursuant to Section 303 of the Base Indenture.

or by wire transfer to an account appropriately designated by the Holder entitled to payment.

     No service charge shall be made for any registration of transfer or exchange of the Senior Notes, but the Company may require payment from the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

In the event of a Successful Remarketing of the Senior Notes, the Coupon Rate will be reset by the Remarketing Agent at the appropriate Reset Rate with effect from the related Reset Effective Date, as set forth under Section 8.03.

In the event that any scheduled Interest Payment Date falls on a day that is not a Business Day, then payment of interest payable on such Interest Payment Date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next calendar year, then such payment will be made on the preceding Business Day.

Following the notice of a Special Event Redemption, neither the Company nor the Trustee shall be required to register the transfer of or exchange the Senior Notes to be redeemed.

     Section 3.02. Redemption Procedures.

     (b) Each Holder of Separate Senior Notes may elect to have Separate Senior Notes held by such Holder remarketed in any Remarketing. A Holder making such an election must, pursuant to the Pledge Agreement, notify the Custodial Agent and deliver such Separate Senior Notes to the Custodial Agent prior to 5:00 P.M.

presented to the Remarketing Agent. Under Section 5.02 of the Purchase Contract Agreement, Senior Notes that are components of Corporate Units will be deemed tendered for Remarketing and will be remarketed in accordance with the terms of the Remarketing Agreement.

     (c) The right of each Holder of Senior Notes that are included in Corporate Units to have such Senior Notes, and each Holder of Separate Senior Notes to have any Separate Senior Notes (together, the “Remarketed Senior Notes”), remarketed and sold on any Remarketing Date shall be limited to the extent that (i) the Remarketing Agent conducts a Remarketing pursuant to the terms of the Remarketing Agreement, (ii) a Special Event Redemption has not occurred prior to such Remarketing Date, (iii) the Remarketing Agent is able to find a purchaser or purchasers for Remarketed Senior Notes at the Remarketing Price or the Final Remarketing Price, as the case may be, and (iv) the purchaser or purchasers deliver the purchase price therefor to the Remarketing Agent as and when required.

(a) Unless a Special Event Redemption has occurred prior to the Initial Remarketing Date, on the Initial Remarketing Date, the Remarketing Agent shall, pursuant and subject to the terms of the Remarketing Agreement, use its reasonable efforts to remarket the Remarketed Senior Notes at a price (the “Remarketing Price”) equal to approximately 100.25% of the sum of the Treasury Portfolio Purchase Price and the Separate Senior Note Purchase Price.

     (b) In the case of a Failed Initial Remarketing and unless a Special Event Redemption has occurred prior to the Final Remarketing Date, on the Final Remarketing Date, the Remarketing Agent shall use its reasonable efforts to remarket the Remarketed Senior Notes at a price (the “Final Remarketing Price”) equal to approximately 100.25% of the aggregate principal amount of the Remarketed Senior Notes. It is understood and agreed that Remarketing on any Remarketing Date will be considered successful and no further attempts will be made if the resulting proceeds are at least 100.25% of the sum of the Treasury Portfolio Purchase Price and the Separate Senior Note Purchase Price, in the case of the Initial Remarketing, or 100.25% of the aggregate principal amount of the Remarketed Senior Notes in the case of the Final Remarketing.

     Section 8.03. Reset Rate. (a) In connection with each Remarketing, the Remarketing Agent shall determine the Reset Rate (rounded to the nearest one-thousandth (0.001) of one percent per annum) that the Remarketed Senior Notes

should bear in order to have an aggregate market value equal to the Remarketing Price or the Final Remarketing Price, as the case may be, and that in the sole discretion of the Remarketing Agent will enable it to remarket all of the Remarketed Senior Notes at the Remarketing Price or Final Remarketing Price, as the case may be, in such Remarketing.

     (b) Anything herein to the contrary notwithstanding, the Reset Rate shall in no event exceed the maximum rate permitted by applicable law and the Remarketing Agent shall have no obligation to determine whether there is any limitation under applicable law on the Reset Rate or, if there is any such limitation, the maximum permissible Reset Rate on the Senior Notes and they shall rely solely upon written notice from the Company (which the Company agrees to provide prior to the eighth Business Day before the Initial Remarketing Date) as to whether or not there is any such limitation and, if so, the maximum permissible Reset Rate.

     (c) In the event of a Failed Remarketing or if no Senior Notes are included in Corporate Units and none of the holders of the Separate Senior Notes elect to have their Senior Notes remarketed in any Remarketing, the applicable interest rate on the Senior Notes will not be reset and will continue to be the Coupon Rate.

     (d) In the event of a Successful Remarketing, the Coupon Rate shall be reset at the Reset Rate as determined by the Remarketing Agent under the Remarketing Agreement.

     Section 8.04. Failed Remarketing. (a) If, by 4:00 p.m. (New York City time) on any Remarketing Date, the Remarketing Agent is unable to remarket all of the Remarketed Senior Notes at the Remarketing Price or the Final Remarketing Price, as the case may be, pursuant to the terms and conditions hereof, a Failed Remarketing shall be deemed to have occurred, and the Remarketing Agent shall so advise, by telephone the Depositary, the Purchase Contract Agent and the Company. Promptly following any Failed Remarketing, the Remarketing Agent shall return Separate Senior Notes submitted for remarketing, if any, to the Custodial Agent for distribution to the appropriate Holders.

     (b) The Company shall cause a notice of such Failed Remarketing to be published in a daily newspaper in the English language of general circulation in the City of New York, which is expected to be The Wall Street Journal.

     Section 8.05. Put Right. (a) If there has not been a Successful Remarketing prior to the Purchase Contract Settlement Date, Holders of Separate Senior Notes and Holders of Senior Notes that are a component of Corporate

Units will, subject to this Section 8.05, have the right (the “Put Right”) to require the Company to purchase their Senior Notes, on the Purchase Contract Settlement Date, at a price per Senior Note equal to $50.00 plus accrued and unpaid interest to but excluding the Purchase Contract Settlement Date (the “Put Price”).

     (b) The Put Right of Holders of Senior Notes that are part of Corporate Units will be automatically exercised unless such Holders (1) prior to 11:00 a.m., New York City time, on the second Business Day immediately preceding the Purchase Contract Settlement Date, provide written notice to the Purchase Contract Agent of their intention to settle the related Purchase Contract with separate cash, and (2) on or prior to the Business Day immediately preceding the Purchase Contract Settlement Date, deliver to the Collateral Agent $50 in cash per Purchase Contract, in each case pursuant to the Purchase Contract Agreement. Unless a Corporate Unit holder has settled the related Purchase Contract with separate cash on or prior to the Purchase Contract Settlement Date, the Company, on the Purchase Contract Settlement Date, shall cause the Put Price to be deposited in the Collateral Account and the Collateral Agent shall cause the Securities Intermediary to remit the Purchase Price for the shares of Common Stock to be issued under the related Purchase Contract from a portion of the Proceeds of the Put Right to the Company in full satisfaction of such Holder’s obligations under the related Purchase Contract. Any remaining amount of the Put Price following satisfaction of the related Purchase Contract will be paid to such Corporate Unit holder. If the Company shall fail to pay the Put Price on the Purchase Contract Settlement Date in accordance with the foregoing, the Company shall be deemed to have netted its obligation to pay the Put Price against the obligation of a Holder of a Senior Note that is a component of a Corporate Unit to pay the Purchase Price under the related Purchase Contract on the Purchase Contract Settlement Date.

     (c) The Put Right of a Holder of a Separate Senior Note shall only be exercisable upon delivery of a notice to the Trustee by such Holder on or prior to the second Business Day prior to the Purchase Contract Settlement Date. On or prior to the Purchase Contract Settlement Date, the Company shall deposit with the Trustee immediately available funds in an amount sufficient to pay, on the Purchase Contract Settlement Date, the aggregate Put Price of all Separate Senior Notes with respect to which a Holder has exercised a Put Right. In exchange for any Separate Senior Notes surrendered pursuant to the Put Right, the Trustee shall then distribute such amount to the Holders of such Separate Senior Notes.

     Section 8.06. Additional Event of Default. In addition to the events listed as Events of Default in Section 501 of the Base Indenture, it shall be an additional Event of Default with respect to the Senior Notes, if the Company shall not have satisfied its obligation to pay the Put Price when due in accordance with

Section 8.05 (either by payment of the Put Price to the Trustee when due, by deposit of the Put Price in the Collateral Account when due or by netting the Put Price against a Holder’s obligation under the related Purchase Contract if a Senior Note is a component of a Corporate Unit).

ARTICLE 9
Tax Treatment

     Section 9.01. Tax Treatment.
