 will be extended by the number of days during such period on which no such registration statement is effective or a blackout period is continuing ( provided that the fundamental change exercise period will not be extended beyond the third scheduled trading day preceding the purchase contract settlement date) and the fundamental change early settlement date will be postponed to the third scheduled trading day following the end of the fundamental change exercise period. The Company will provide each of the holders and the purchase contract agent with a notice of any such extension and postponement at least 23 scheduled trading days prior to any such extension and postponement.

Unless the Treasury portfolio has replaced the RSNs as a component of the Corporate Units as a result of a successful optional remarketing, holders of Corporate Units may exercise the fundamental change early settlement right only in integral multiples of 40 Corporate Units. If the Treasury portfolio has replaced the RSNs as a component of Corporate Units, holders of the Corporate Units may exercise the fundamental change early settlement right only in integral multiples of Corporate Units.

A holder of Treasury Units may exercise the fundamental change early settlement right only in integral multiples of 20 Treasury Units.

#### What is the ranking of the RSNs?
The RSNs will be direct, unsecured and unsubordinated obligations of the Company ranking equally with all other unsecured and unsubordinated obligations of the Company from time to time outstanding. Since the Company is a holding company, the right of the Company and, hence, the right of creditors of the Company (including holders of the RSNs) to participate in any distribution of the assets of any subsidiary of the Company, whether upon liquidation, reorganization or otherwise, is structurally subordinated to claims of creditors and any preferred stockholders of each subsidiary. The RSNs will be effectively subordinated to all secured indebtedness of the Company. See “Description of the Remarketable Senior Notes—Ranking” herein and “Description of the Senior Notes—General” in the accompanying Prospectus.

#### How will the RSNs be evidenced?
The RSNs that form a part of the Corporate Units will be issued in fully registered form and will be registered in the name of the purchase contract agent. The RSNs that do not form a part of the Corporate Units will be evidenced by one or more global notes registered in the name of DTC’s nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC.

In a few special situations described in “Description of the Remarketable Senior Notes—Book-Entry
