The details of the FDIC guarantee are provided in the FDIC’s regulations, 12 C.F.R. Part 370, and at the FDIC’s website, www.fdic.gov/tlgp.

The Trustee is hereby designated, and each Holder of the Notes, by its acceptance of a Note, shall be deemed to have appointed the Trustee as the duly authorized representative of the Holders for purposes of making claims and taking other permitted or required actions under the Debt Guarantee Program (the “Representative”). Any Holder may elect not to be represented by the Representative by providing written notice of such election to the Representative (it being understood that such election shall not affect the Trustee’s capacity hereunder except as the representative of such Holder under the Debt Guarantee Program). The Company hereby authorizes and directs the Representative to take all actions on behalf of the Holders that the Representative is required or empowered to take on behalf of the Holders pursuant to the Debt Guarantee Program. Until instructed by Holders of not less than 25% in aggregate principal amount of the Notes, the Representative shall have no duty or obligation to take any action which it is empowered but not required to take and shall have no liability or responsibility for failure to do so. For avoidance of doubt, the obligations of the Representative pursuant to Section 3.12 hereto shall be deemed to be required actions.

SECTION 3.05. Subrogation. The FDIC shall be subrogated to all of the rights of the Holders and the Representative under the Notes and the Indenture against the Company in respect of any amounts paid to the Holders, or for the benefit of the Holders, by the FDIC pursuant to the Debt Guarantee Program.

SECTION 3.06. Agreement to Execute Assignment upon Guarantee Payment. The Holders, by acceptance of the Notes, hereby authorize and direct the Representative, at such time as the FDIC shall commence making any guarantee payments to the Representative for the benefit of the Holders pursuant to the Debt Guarantee Program, to execute an assignment in the form attached to each Note pursuant to which the Representative shall assign to the FDIC its right as Representative to receive any and all payments from the Company under the Notes, on behalf of the Holders. The Company hereby consents and agrees that the FDIC is an acceptable transferee for all or any portion of the indebtedness hereunder for all purposes of the

7

Notes, and upon any such assignment, the FDIC shall be deemed the Holder of the Notes, for all purposes hereof, and the Company hereby agrees to take such reasonable steps as are necessary to comply with any relevant provision of the Notes and the Indenture as a result of such assignment.

If a Holder has exercised its right not to be represented by the Representative, such Holder, by its acceptance of the Notes, agrees that, at such time as the FDIC shall commence making any guarantee payments to the Representative for the benefit of the Holders pursuant to the Debt Guarantee Program, such Holder shall execute an assignment in the form attached to each Note pursuant to which the Holder shall assign to the FDIC its right to receive any and all payments from the Company under the Notes and the Indenture.

SECTION 3.07. Surrender of Senior Unsecured Debt Instrument to the FDIC. If, at any time on or prior to the expiration of the period during which senior unsecured debt of the Company is guaranteed by the FDIC under the Debt Guarantee Program (the “Effective Period”), payment in full hereunder shall be made pursuant to the Debt Guarantee Program on the outstanding principal and accrued interest to such date of payment, the Holder shall, or the Holder shall cause the person or entity in possession to, promptly surrender to the FDIC their Notes or other instrument evidencing such Notes, if any.

SECTION 3.08. Notice Obligations to FDIC of Payment Default. If, at any time prior to the earlier of (a) full satisfaction of the payment obligations in respect of the Notes, or (b) expiration of the Effective Period, the Company is in default of any payment obligation hereunder, including timely payment of any accrued and unpaid interest on the Notes, without regard to any cure period, the Representative and the Company covenant and agree that each shall provide written notice to the FDIC within one (1) Business Day of such payment default at the address set forth below, or at such other address or by such other means of delivery as the FDIC may specify from time to time:

SECTION 3.09. Ranking. Any indebtedness of the Company to the FDIC arising under Section 2.03 of the Master Agreement will constitute a senior unsecured general obligation of the Company, ranking pari passu with the Notes.

8

SECTION 3.10. No Event of Default During Time of Timely FDIC Guarantee Payments. There shall not be deemed to be an Event of Default under the Notes or the Indenture which would permit or result in the acceleration of amounts due hereunder, if such Event of Default is due solely to the failure of the Company to make timely payment hereunder; provided that the FDIC is making timely guarantee payments with respect to the Notes, in accordance with 12 C.F.R Part 370.

Without limiting the foregoing, under no circumstances shall an Event of Default specified in Sections 501(3) through 501(8) of the Original Indenture result in any acceleration of the amounts due under the Notes.

SECTION 3.11. No Modifications Without FDIC Consent. Notwithstanding anything to the contrary contained herein, without the express written consent of the FDIC, the Company and the Trustee agree not to amend, modify, supplement or waive any provision in the Notes or the Indenture that is related to the principal, interest, payment, default or ranking of the indebtedness of the Notes or that is required to be included herein pursuant to the Master Agreement, or any provision herein or therein that would require the consent of each Holder of the Notes.

SECTION 3.12. Demand Obligations to FDIC upon the Company’s Failure to Pay. Within one (1) Business Day following the 30th day after the date the Company defaults in payment of interest on the Notes (which default has not been cured by the Company by such 30th day), in the case of default in interest or, within one (1) Business Day following the day of Maturity, in the case of default in principal of the Notes, the Representative shall make a demand, on behalf of the Holders of the Notes, to the FDIC for payment on the guaranteed amount under the Debt Guarantee Program. Such demand shall be accompanied by a proof of claim, which shall include evidence in form and content satisfactory to the FDIC, of: (A) the Representative’s financial and organizational capacity to act as Representative; (B) the Representative’s exclusive authority to act on behalf of the Holders of such Notes and its fiduciary responsibility to the Holders of such Notes when acting as such, as established by the terms of the Notes and the Indenture; (C) the occurrence of a payment default; and (D) the authority to make an assignment of the Holders’ right, title and interest in the Notes to the FDIC and to effect the transfer to the FDIC of the Holders’ claim in any insolvency proceeding. Such assignment shall include the right of the FDIC to receive any and all distributions on the Notes, from the proceeds of the receivership or bankruptcy estate. Any demand under this Section 3.12 shall be made in writing and directed to the Director, Division of Resolution and Receiverships, Federal Deposit Insurance Corporation, Washington, D.C., and shall include all supporting evidences as provided in this Section 3.12, and shall certify to the accuracy thereof.

(iv) any tax, assessment or other governmental charge imposed solely because such beneficial owner or any other Person fails to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection with the United States of the Holder or any beneficial owner of this Security, if compliance is required by statute, by regulation of the U.S. Treasury Department or by an applicable income tax treaty to which the United States is a party, as a precondition to exemption from such tax, assessment or other governmental charge;

A-3

(v) any tax, assessment or other governmental charge that can be paid other than by deduction or withholding from a payment on this Security;

(vi) any tax, assessment or other governmental charge imposed solely because the payment is to be made by a particular Paying Agent (which term may include the Company) and would not be imposed if made by another Paying Agent (which term may include the Company);

(vii) any tax assessment or other governmental charge imposed on a Holder who would be able to avoid such withholding or deduction by presenting this Security to another Paying Agent in a Member State of the European Union;

(viii) any tax, assessment or other governmental charge imposed solely because the Holder (1) is a bank purchasing this Security in the ordinary course of its lending business or (2) is a bank that is neither (A) buying this Security for investment purposes only nor (B) buying this Security for resale to a third party that either is not a bank or holding the note for investment purposes only;

(x) any combination of the taxes, assessments or other governmental charges described in items (i) through (ix) of this paragraph.

Additional Amounts also will not be paid with respect to any payment of principal of or interest on this Security to any United States Alien who is a fiduciary or a partnership, or who is not the sole beneficial owner of any such payment, to the extent that the Company would not be required to pay Additional Amounts to any beneficiary or settlor of such fiduciary or any member of such a partnership, or to any beneficial owner of the payment, if that Person had been treated as the beneficial owner of this Security for this purpose.

Except as specifically provided herein, the Company shall not be required to make any payment with respect to any tax, assessment or other governmental charge imposed by any government or any political subdivision or taxing authority thereof or therein.

Whenever in this Security (or in the Indenture, including in Sections 501(1) and 501(2) thereof, insofar as applicable to this Security) there is a reference, in any context, to the payment of the principal of or interest on this Security, such mention shall be deemed to include mention of any payment of Additional Amounts to United States Aliens in respect of such payment of principal or interest to the extent that, in such context, such Additional Amounts are, were or would be payable in respect thereof. Express mention of the payment of Additional Amounts in this Security shall not be construed as excluding Additional Amounts in the provisions of this Security where such express mention is not made.

The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.
