The proceeds from the sale of the Capital Securities will be combined with the proceeds from the sale of the Common Securities by the Trust to the Company and will be used by the Trust to purchase an equivalent aggregate principal amount of Floating Rate Junior Subordinated Debentures due November 7, 2032 of the Company (the "Debentures"), to be issued by the Company pursuant to an Indenture to be executed by the Company, as Issuer, and Wells Fargo Bank, National Association, as Debenture Trustee (the "Indenture"); and C.

In consideration of the premises and the mutual representations and covenants hereinafter set forth, the parties hereto agree as follows: ARTICLE I PURCHASE AND SALE OF CAPITAL SECURITIES 1.1. Upon the execution of this Subscription Agreement, subject to the conditions precedent set forth in Section 1.5, the Purchaser hereby agrees to purchase from the Trust 3,000 Capital Securities at a price equal to $1,000 per Capital Security (the "Purchase Price") and the Trust agrees to sell such number of Capital Securities with a liquidation amount of $1,000 per Capital Security to the Purchaser for the Purchase Price. The rights and preferences of the Capital Securities will be set forth in the Declaration in form and substance reasonably acceptable to the Purchaser. The Purchase Price is payable by the Purchaser on the Closing Date in immediately available funds to the account designated by Wells Fargo Bank, National Association. 1.2. The certificate for the Capital Securities shall be delivered in definitive form by the Trust on the Closing Date to the Purchaser or its designee, and shall be registered in the name of the Purchaser and shall represent the aggregate liquidation amount of the Capital Securities being purchased by the Purchaser. 1.2.1. The Purchaser acknowledges and the Offerors agree that they will not register any transfer of the Capital Securities not made in accordance with Regulation S, pursuant to registration under the Securities Act of 1933, as amended (the "Securities Act"), or pursuant to an available exemption from registration. 1.3. The Placement Agreement, dated October 16, 2002 (the "Placement Agreement"), among the Offerors and the Placement Agent identified therein includes certain representations and warranties, covenants and conditions to closing and certain other matters governing the issuance and sale of the Capital Securities by the Trust to the Purchaser. Each of the provisions of the Placement Agreement, including the definitions therein, are hereby incorporated by reference into this Subscription Agreement. In addition, to the extent provided for in the Placement Agreement, the Purchaser shall be entitled to the benefits of the Placement Agreement and shall be entitled to enforce such obligations of the Offerors under the Placement Agreement as fully as if the Purchaser were a party to such Placement Agreement, it being agreed between the parties that any and all representations made by the Offerors to the Placement Agent in the Placement Agreement shall be deemed to have also been made to the Purchaser. 1.4. If any condition specified herein or in the Placement Agreement shall not have been fulfilled when and as required to be fulfilled by, on behalf of or in respect of the Offerors or the Capital Securities, this Subscription Agreement may be terminated by the Purchaser by notice to the Offerors at any time at or prior to the Closing Date, and such termination shall be without liability of any party to any other party except that Section 4, 8 and 16 of the Placement Agreement shall survive any such termination and remain in full force and effect. 1.5. If the CBO Offering is not successfully completed for any reason, including, without limitation, as a result of the inability of the Purchaser to acquire sufficient subordinated debt and capital securities from the Trust and other issuers and sellers in a quantity and with other particular characteristics, in the aggregate, sufficient to satisfy rating agency criteria with respect to expected ratings on the notes to be issued by the Purchaser and other criteria deemed necessary or advisable by the Purchaser, all obligations of the Purchaser hereunder shall terminate and be extinguished. 1.6. Notwithstanding any other provision of this Subscription Agreement, the obligations of the Purchaser hereunder are limited recourse obligations of the Purchaser, payable solely from the proceeds of the CBO Offering, and if the CBO Offering is not completed or the 2 proceeds of the CBO Offering are insufficient to satisfy the obligations of the Purchaser, any claims hereunder shall be extinguished. The Trust, Wells Fargo Bank, National Association (on behalf of the Trust) and the Company further agree (i) not to take any action in respect of any claims hereunder against any subscriber, officer, director, employee or administrator of the Purchaser and (ii) not to institute against the Purchaser any insolvency, bankruptcy, reorganization, liquidation or similar proceedings in any jurisdiction until one year and one day or, if longer, the applicable preference period then in effect, shall have elapsed since the final payments to the holders of the notes issued by the Purchaser in connection with the CBO Offering.
