The Registration Statement provides that Debt Securities may be convertible into shares of Common Stock or shares of Preferred Stock, and that shares of Preferred Stock may be convertible into shares of Common Stock. All securities that may be sold by the Company, CBC and the Trusts will be newly issued. 2 The Debt Securities and the Debt Guarantees will be issued pursuant to one or more indentures in a form filed as an exhibit to the Registration Statement, as amended or supplemented from time to time (each, an "Indenture"), between the Company or CBC, as applicable, as obligor, and a trustee chosen by the Company or CBC, as applicable, and qualified to act as such under the Trust Indenture Act of 1939, as amended (each, a "Trustee").

The Purchase Contracts will be issued under one or more Purchase Contract Agreements in the form filed as an exhibit to the Registration Statement, as amended or supplemented from time to time (each, a "Purchase Contract Agreement"), by and between the Company and a purchase contract agent. The Preferred Securities are to be issued from time to time by each Trust pursuant to an Amended and Restated Declaration of Trust (the "Amended Declaration") to be filed with the Secretary of State of the State of Delaware by the Trustee of the relevant Trust.
