     (r) Neither the Guarantor nor any subsidiary is in violation or default of (i) any provision of its charter or by-laws, (ii) the terms of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or instrument to which it is a party or bound or to which its property is subject or (iii) any statute, law, rule, regulation, judgment, order or decree of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Guarantor or such subsidiary or any of its properties, as applicable, which violation or default would, in the case of clauses (ii) and (iii) above, either individually or in the aggregate with all other violations and defaults referred to in this paragraph (r), reasonably be expected to result in a Material Adverse Effect.

     (s) The Guarantor has filed all foreign, federal, state and local tax returns that are required to be filed or has requested extensions thereof (except in any case in which the failure so to file would not reasonably be expected to have a Material Adverse Effect) and has paid all taxes required to be paid by it and any other assessment, fine or penalty to the extent that any of the foregoing is due and payable, except for any that is currently being contested in good faith or as would not reasonably be expected to result in a Material Adverse Effect.

     (u) No subsidiary of the Guarantor is currently prohibited, directly or indirectly, from paying any dividends to the Guarantor, from making any other distribution on such subsidiary’s capital stock, from repaying to the Guarantor any loans or advances to such subsidiary from the Guarantor or from transferring any of such subsidiary’s property or assets to the Guarantor or any other subsidiary of the Guarantor except as described in or contemplated by the Pricing Prospectus and applicable banking laws and regulations.

     (v) The Guarantor and its Significant Subsidiaries possess all licenses, certificates, permits and other authorizations issued by the appropriate federal, state or foreign regulatory authorities necessary to conduct their respective businesses except those the failure of which to possess would not reasonably be expected to result in a Material Adverse Effect, and neither the Guarantor nor any such subsidiary has received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to result in a Material Adverse Effect.

     (w) Ernst & Young LLP, independent registered public accounting firm, who have audited consolidated financial statements of the Guarantor and its consolidated subsidiaries, and delivered their report with respect to audited consolidated financial statements included in the Prospectus, is an independent registered public accounting firm as required by the Securities Act and the rules and regulations of the Commission thereunder.

     (x) The Guarantor maintains a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) that complies with the requirements of the Exchange Act and has been designed by the Guarantor’s principal executive officer and principal financial officer, or under their supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

     (bb) Except as disclosed in the Registration Statement and the Pricing Prospectus, the Guarantor does not have any material lending or other material relationship with any bank or lending affiliate of any of the Underwriters.

     (cc) The Guarantor and each of its subsidiaries are in compliance with all laws administered by the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”), the Federal Deposit Insurance Corporation (“FDIC”), the Alabama Department of Banking (the “Department”) and any other federal or state bank regulatory authorities (together with the Federal Reserve Board, the FDIC and the Department, the “Bank Regulatory Authorities”) with jurisdiction over the Guarantor and its subsidiaries, except for such failures to be in compliance as would not reasonably be expected to result in a Material Adverse Effect. The deposit accounts of each bank subsidiary of the Guarantor are insured up to applicable limits by the FDIC and no proceedings for the termination or revocation of such insurance are pending or, to the knowledge of the Guarantor, threatened. Neither the Guarantor nor any of its Significant Subsidiaries is a party to or otherwise subject to any consent decree, memorandum of understanding, written commitment or other supervisory agreement with any of the Bank Regulatory Authorities or any other governmental agency or authority, nor have the Guarantor or any of its Significant Subsidiaries been advised by any of the Bank Regulatory Authorities or any other governmental agency or authority that it is contemplating issuing or requesting any of the foregoing.

     (dd) To the Guarantor’s knowledge, the operations of the Guarantor and its subsidiaries are currently in compliance with applicable financial record keeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all United States jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency in the United States (collectively, the “Money Laundering Laws”), except where the failure to so comply would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect; and no formal action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Guarantor or any of its subsidiaries with respect to the Money Laundering Laws is pending or, to the knowledge of the Guarantor, threatened that would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

     (ee) Except as previously disclosed to the Representative, neither the Guarantor nor any of its affiliates does business with the government of, or any person located in, any country, or with any other person, targeted by any of the economic sanctions of the United States administered by the United States Treasury Department’s Office of Foreign Assets Control; the Guarantor is not controlled (within the meaning of the regulations promulgating such sanctions or the laws authorizing such promulgation) by any such government or person; and the proceeds from the offering will not be used to fund any operations in, finance any investments or activities in or make any payments to, any country, or to make any payments to any person, targeted by any of such sanctions.

          As compensation to the Underwriters for their commitments hereunder, and in view of the fact that the proceeds from the sale of the Trust Preferred Securities will be used by the Trust to purchase the Junior Subordinated Notes, the Guarantor on the Closing Date will pay by wire transfer of immediately available funds to Goldman, Sachs & Co., for the accounts of the several Underwriters, the amount per Trust Preferred Security set forth in Schedule II in respect of the Trust Preferred Securities to be delivered by the Trust hereunder on the Closing Date.

Guarantor (such date and time of delivery of and payment for the Trust Preferred Securities being herein called the “Closing Date”). The Trust Preferred Securities to be purchased by each Underwriter hereunder will be represented by one or more global certificates representing the Trust Preferred Securities that will be deposited by or on behalf of the Trust with The Depository Trust Company (“DTC”) or its designated custodian.

     (f) During the period beginning from the date of the Prospectus, and continuing to and including the date 30 days after the date of the Prospectus or such earlier time as you may notify the Guarantor, not to offer, sell, contract to sell, or otherwise dispose of, directly or indirectly, any Trust Preferred Securities (except for (x) the Trust Preferred Securities offered hereby and (y) any securities to be offered in an exchange offer or similar transaction in respect of securities outstanding on the date hereof, in each case including any guarantee of such securities), any other beneficial interests in the assets of the Trust (other than the Trust Common Securities) or any Junior Subordinated Notes, any securities (including any security issued by another trust or other limited purpose vehicle)

that are substantially similar to the Trust Preferred Securities, the Junior Subordinated Notes, the Guarantee, or any securities that are convertible into or exchangeable for or that represent the right to receive any such substantially similar securities of either the Trust, a similar trust or the Guarantor, except with your prior written consent.

     (g) To use the net proceeds received from the sale of the Trust Preferred Securities or Junior Subordinated Notes, as the case may be, in the manner specified in the Pricing Prospectus under the caption “Use of Proceeds.”

     (ii) The Guarantor has been duly qualified as a foreign corporation for the transaction of business and is in good standing under the laws of each other jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification or is subject to no material liability or disability by reason of the failure to be so qualified in any such jurisdiction (except in any case in which the failure so to file would not reasonably be expected to have a Material Adverse Effect);

     (iii) Each Significant Subsidiary of the Guarantor has been duly incorporated and is validly existing as a corporation or bank, as applicable, in good standing under the laws of its jurisdiction of incorporation; and all of the issued shares of capital stock of each Significant Subsidiary have been duly and validly authorized and issued, are fully paid and non-assessable, and (except for directors qualifying shares and as otherwise set forth in the Prospectus), are owned directly or indirectly by the Guarantor free and clear of all liens, encumbrances, equities or claims (such counsel being entitled to rely in respect of the opinion in this clause upon opinions of local counsel and in respect of matters of fact upon certificates of officers of the Guarantor or its Significant Subsidiaries, provided that such counsel shall state that they believe that both the Guarantor and the Underwriters are justified in relying upon such opinions and certificates);

     (iv) To such counsel’s knowledge and other than as set forth in the Prospectus, there are no legal or governmental proceedings pending to which the Guarantor or any of its Significant Subsidiaries or the Trust is a party or of which any property of the Guarantor or any of its Significant Subsidiaries or the Trust is the subject which is reasonably likely to be adversely determined against the Guarantor or any of its subsidiaries or the Trust and, if determined adversely to the Guarantor or any of its subsidiaries or the Trust, would individually or in the aggregate have a material adverse effect on the current or future consolidated financial position, stockholders’ equity or results of operations of the Guarantor and its Significant Subsidiaries, taken as a whole, or of the Trust; and, to such counsel’s knowledge, no such proceedings are threatened by governmental authorities;

     (v) The documents incorporated by reference in the Prospectus or any further amendment or supplement thereto made by the Guarantor prior to the Time of Delivery (other than the financial statements and related schedules therein, as to which such counsel need express no opinion), when they became effective or were filed with the Commission, as the case may be, complied as to form in all material respects with the requirements of the Securities Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder; and they have no reason to believe that any of such documents, when such documents became effective or were so filed, as the case may be, contained, in the case of a registration statement which became effective under the Securities Act, an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or, in the case of other documents which were filed under the Securities Act or the Exchange Act with the Commission, an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light

     (viii) No consent, approval, authorization, order, registration or qualification of or with any court or governmental agency or body is required for the issue and sale of the Trust Preferred Securities or the Junior Subordinated Notes or the consummation by the Guarantor and the Trust of the transactions contemplated by the Underwriting Agreement, except such as have been obtained under the Securities Act and such consents, approvals, authorizations, or registrations as may be required under state securities or Blue Sky laws in connection with the purchase and distribution of the Trust Preferred Securities by the Underwriters;

     (d) Richards, Layton & Finger, P.A., special Delaware counsel to the Guarantor and the Trust, shall have furnished to the Underwriters an opinion, dated the Closing Date, to the effect that:

     (ii) Under the Delaware Statutory Trust Act and the Declaration of Trust, the Trust has the trust power and authority to own its property and conduct its business, all as described in the Prospectus;

     (iii) The provisions of the Declaration of Trust, including the terms of the Trust Preferred Securities, are permitted under the Delaware Statutory Trust Act and the Declaration of Trust constitutes a valid and binding obligation of the Guarantor and the Trustees, enforceable against the Guarantor and the Trustees in accordance with its terms, subject, as to enforcement, to the effect upon the Declaration of Trust of (i) bankruptcy, insolvency, moratorium, receivership, reorganization, liquidation, fraudulent conveyance or transfer and other similar laws relating to or affecting the rights and remedies of creditors generally, (ii) principles of equity, including applicable law relating to fiduciary duties (regardless of whether considered and applied in a proceeding in equity or at law), and (iii) applicable public policy on the enforceability of provisions relating to indemnification or contribution;

     (iv) Under the Delaware Statutory Trust Act and the Declaration of Trust, the Trust has the trust power and authority to (x) execute and deliver this Agreement and the Expense Agreement and to perform its obligations under this Agreement and the Expense Agreement, and (y) issue and perform its obligations under the Trust Preferred Securities and the Trust Common Securities;

     (v) Under the Delaware Statutory Trust Act and the Declaration of Trust, (A) the execution and delivery by the Trust of this Agreement and the Expense Agreement and the performance by the Trust of its obligations hereunder and thereunder have been duly authorized by all necessary trust action on the part of the Trust; and (B) the Guarantor is authorized to execute and deliver this Agreement on behalf of the Trust;

     (vi) Under the Delaware Statutory Trust Act, the form of certificate attached to the Declaration of Trust to represent the Trust Preferred Securities is an appropriate form of certificate to evidence ownership of the Trust Preferred Securities. The Trust Preferred

Securities have been duly authorized by the Declaration of Trust and, when delivered to and paid for by the Underwriters, in accordance with this Agreement, will be validly issued and fully paid and non-assessable beneficial interests in the Trust. The holders of the Trust Preferred Securities are entitled to the benefits provided by the Declaration of Trust (subject to the terms of the Declaration of Trust); and the holders of the Trust Preferred Securities, as beneficial owners of the Trust, will be entitled to the same limitation of personal liability extended to stockholders of private corporations for profit organized under the General Corporation Law of the State of Delaware, provided that such counsel may note that the holders of the Trust Preferred Securities and of the Trust Common Securities may be obligated, pursuant to the Declaration of Trust, to (a) provide indemnity and/or security in connection with, and pay taxes or governmental charges arising from, transfers or exchanges of Trust Preferred Security certificates and the issuance of replacement of Trust Preferred Security certificates, and (b) provide security and indemnity in connection with requests of or directions to the Property Trustee (as defined in the Declaration of Trust) to exercise its rights and remedies under the Declaration of Trust;

The Guarantor, as holder of the Trust Common Securities, will be entitled to the benefits of the Declaration of Trust;

     (viii) Under the Delaware Statutory Trust Act and the Declaration of Trust, the issuance of the Trust Preferred Securities and the Trust Common Securities is not subject to preemptive rights;

     (ix) The issuance and sale by the Trust of the Trust Preferred Securities and the Trust Common Securities, the execution, delivery and performance by the Trust of this Agreement and the Expense Agreement, the consummation by the Trust of the transactions contemplated hereby and thereby and compliance by the Trust with its obligations hereunder and thereunder do not violate (A) any of the provisions of the Certificate of Trust of the Trust or the Declaration of Trust, or (B) any applicable Delaware law or administrative regulation;

     (x) No authorization, approval, consent or order of any Delaware court or Delaware governmental authority or Delaware agency is required to be obtained by the Trust solely in connection with the issuance and sale of the Trust Preferred Securities and the Trust Common

Securities or the execution, delivery and performance by the Trust of this Agreement or the Expense Agreement. In rendering the opinion expressed in this paragraph (x), such counsel need express no opinion concerning the securities laws of the State of Delaware; and

     (xi) Assuming that the Trust derives no income from or connected with services provided within the State of Delaware and has no assets, activities (other than maintaining the Delaware Trustee and the filing of documents with the Secretary of State of the State of Delaware) or employees in the State of Delaware and assuming that the Trust is treated as a grantor trust or as an association not taxable as a corporation for federal income tax purposes, the holders of Trust Preferred Securities (other than those holders who reside or are domiciled in the State of Delaware) will have no liability for income taxes imposed by the State of Delaware solely as a result of their participation in the Trust, and the Trust will not be liable for any income tax imposed by the State of Delaware.

     (e) The Underwriters shall have received from Sullivan & Cromwell LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date, with respect to such matters as the Underwriters may reasonably require. Sullivan & Cromwell LLP may rely as to those matters that relate to the Indenture Trustee, the Guarantee Trustee or the Property Trustee upon the certificate or certificates of such entities.

     (f) On the date of the Prospectus at a time prior to the execution of this Agreement, at 9:30 A.M., New York City time, on the effective date of any post-effective amendment to the Registration Statement filed subsequent to the date of this Agreement and also at the Time of Delivery, Ernst & Young LLP shall have furnished to you a letter or letters, dated the respective dates of delivery thereof, in form and substance satisfactory to you, to the effect set forth in Annex I hereto (the executed copy of the letter delivered prior to the execution of this Agreement is attached as Annex I(a) hereto and a form of letter to be delivered on the effective date of any post-effective amendment to the Registration Statement, and as of the Time of Delivery is attached as Annex I(b) hereto).

     (g) Neither the Guarantor nor any of its subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Pricing Prospectus any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Pricing Prospectus, and (ii) since the respective dates as of which information is given in the Pricing Prospectus there shall not have been any change in the capital stock or long-term debt of the Guarantor or any of its subsidiaries or any change, or any development involving a prospective change, in or affecting the financial position,

stockholders’ equity or results of operations of the Guarantor and its subsidiaries, otherwise than as set forth or contemplated in the Pricing Prospectus, the effect of which, in any such case described in clause (i) or (ii), is in the judgment of the Representative so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Trust Preferred Securities on the terms and in the manner contemplated in the Prospectus.

     (h) The Guarantor shall have complied with the provisions of the first sentence of Section 5(A)(d) hereof with respect to the furnishing of prospectuses on the business day next succeeding the date of this Agreement.

     (i) On or after the Applicable Time, the Trust Preferred Securities shall have been accorded a rating of not less than “BBB+” by Standard & Poor’s Ratings Service, not less than “A2” by Moody’s Investors Service, Inc. and not less than “A” by Fitch Ratings.

     (j) On or after the Applicable Time (i) no downgrading shall have occurred in the rating accorded the Guarantor’s debt securities or preferred stock by any “nationally recognized statistical rating organization,” as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Securities Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Guarantor’s debt securities or preferred stock.

     (k) On or after the Applicable Time there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange; (ii) a suspension or material limitation in trading in the Guarantor’s securities on the New York Stock Exchange; (iii) a general moratorium on commercial banking activities declared by either Federal, New York, or Alabama authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war or (v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in the judgment of the Representative makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Trust Preferred Securities on the terms and in the manner contemplated in the Prospectus.

     (l) The Guarantor and the Trust shall have furnished or caused to be furnished to you at the Time of Delivery certificates of officers of the Company and trustees of the Trust satisfactory to you as to the accuracy of the representations and warranties of the Company and the Trust herein at and as of such time, as to the performance by the Guarantor and the Trust of all of their

respective obligations hereunder to be performed at or prior to such time, as to the matters set forth in subsections (a) and (g) of this Section and as to such other matters as you may reasonably request.

          7. Indemnification and Contribution.

     (a) The Guarantor and the Trust will, jointly and severally, indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any Pricing Disclosure Package, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that neither the Guarantor nor the Trust shall be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any Pricing Disclosure Package in reliance upon and in conformity with written information furnished to the Guarantor or the Trust by any Underwriter through the Representative expressly for use therein.

     (b) Each Underwriter will indemnify and hold harmless each of the Guarantor and the Trust against any losses, claims, damages or liabilities to which the Guarantor or the Trust may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, or any Pricing Disclosure Package or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing

Prospectus or the Prospectus, or any such amendment or supplement thereto or any Issuer Free Writing Prospectus, or any Pricing Disclosure Package in reliance upon and in conformity with written information furnished to the Guarantor or the Trust by such Underwriter through the Representative expressly for use therein; and will reimburse the Guarantor or the Trust for any legal or other expenses reasonably incurred by the Guarantor or the Trust, as appropriate, in connection with investigating or defending any such action or claim as such expenses are incurred.

     (c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

     (d) If the indemnification provided for in this Section 7 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as

is appropriate to reflect the relative benefits received by the Guarantor and the Trust on the one hand and the Underwriters on the other from the offering of the Trust Preferred Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Guarantor or the Trust on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Guarantor or the Trust on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Guarantor or the Trust bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Guarantor or the Trust on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Guarantor and the Trust on the one hand and the Underwriters on the other agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Trust Preferred Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

     (e) The obligations of the Guarantor under this Section 7 shall be in addition to any liability which the Guarantor or the Trust may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Securities Act; and the obligations of the Underwriters under this Section 7 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Guarantor and the Trust and to each person, if any, who controls the Guarantor within the meaning of the Securities Act.

     8. Underwriter Default. (a) If any Underwriter shall default in its obligation to purchase the Trust Preferred Securities which it has agreed to purchase hereunder, you may in your discretion arrange for you or another party or other parties to purchase such Trust Preferred Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter, you do not arrange for the purchase of such Trust Preferred Securities, then the Guarantor shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representative to purchase such Trust Preferred Securities on such terms. In the event that, within the respective prescribed periods, you notify the Guarantor that you have so arranged for the purchase of such Trust Preferred Securities, or the Guarantor notifies you that it has so arranged for the purchase of such Trust Preferred Securities, you or the Guarantor shall have the right to postpone the Closing Date for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Guarantor agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus that in your opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Trust Preferred Securities.

          (b) If, after giving effect to any arrangements for the purchase of the Trust Preferred Securities of a defaulting Underwriter or Underwriters by you and the Guarantor as provided in paragraph (a) above, the aggregate principal amount of such Trust Preferred Securities which remains unpurchased does not exceed one eleventh of the aggregate principal amount of all the Trust Preferred Securities, then the Guarantor shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Trust Preferred Securities which such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Trust Preferred Securities which such Underwriter agreed to purchase hereunder) of the Trust Preferred Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

          (c) If, after giving effect to any arrangements for the purchase of the Trust Preferred Securities of a defaulting Underwriter or Underwriters by you and the Guarantor as provided in paragraph (a) above, the aggregate principal amount of Trust Preferred Securities which remains unpurchased exceeds one eleventh of the aggregate principal amount of all the Trust Preferred Securities, or if the Guarantor shall not exercise the right described in paragraph (b) above to require non-defaulting Underwriters to purchase Trust Preferred Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Guarantor, except for the indemnity and contribution agreements in Section 7; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

          9. Expenses on Termination. If for any reason the Trust Preferred Securities are not delivered by or on behalf of the Guarantor as provided herein other than because of a termination of this Agreement pursuant to Section 8, the Guarantor will reimburse the Underwriters through you for all reasonable out-of-pocket expenses approved in writing by you, including reasonable fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Trust Preferred Securities but the Guarantor shall then be under no further liability to any Underwriter except as provided in Section 5A(i) and Section 7. If this Agreement shall be terminated pursuant to Section 8 hereof, the Guarantor and the Trust shall not then be under any liability to any Underwriter with respect to the Trust Preferred Securities, except as provided in Sections 5A(i) and 7 hereof.

          10. Time of the Essence. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

          11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Guarantor or its officers, of the Trust and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, the Guarantor or the Trust or any of the controlling persons referred to in Section 7(e) hereof, and will survive delivery of and payment for the Trust Preferred Securities. The provisions of Sections 5(A)(i) and 7 hereof shall survive the termination or cancellation of this Agreement.

          12. Arm’s-Length Terms. The Trust and the Guarantor acknowledge and agree that (i) the purchase and sale of the Trust Preferred Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Trust and the Guarantor, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Trust or the Guarantor; (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Trust or the Guarantor with respect to the offering contemplated hereby or the process leading

thereto (irrespective of whether such Underwriter has advised or is currently advising the Trust or the Guarantor on other matters) or any other obligation to the Trust or the Guarantor except the obligations expressly set forth in this Agreement and (iv) the Trust and the Guarantor have consulted their own legal and financial advisors to the extent they deemed appropriate. The Trust and the Guarantor each agree that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Trust or the Guarantor, in connection with such transaction or the process leading thereto.

          13. Prior Agreements. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Guarantor and the Underwriters, or the Trust and the Underwriters, or the Guarantor or the Trust and any of the Underwriters, with respect to the subject matter hereof.

          14. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors, heirs, executors, and administrators, and the officers and directors and controlling persons referred to in Section 7 hereof, and no other person will have any right or obligation hereunder.

          15. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York.

          16. Waiver of Jury Trial. The Guarantor, the Trust and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

          17. Counterparts; Notices. This Agreement may be signed in any number of counterparts, each of which shall be deemed an original, which taken together shall constitute one and the same instrument.

          All notices hereunder shall be in writing or by telegram if promptly confirmed in writing, and if to the Underwriters shall be sufficient in all respects if delivered or sent by mail, telex or facsimile transmission to the address of Goldman, Sachs & Co., as set forth in Schedule II hereto; and if to the Guarantor or the Trust shall be sufficient in all respects if delivered or sent by mail, telex or facsimile transmission to its address set forth in the Registration Statement, Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 7(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Guarantor by the Underwriters upon request.

          18. Disclosure of Tax Treatment. Notwithstanding anything herein to the contrary, the Guarantor and the Trust are authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction

and all materials of any kind (including tax opinions and other tax analyses) provided to the Guarantor and the Trust relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

          19. Action by Underwriters. Any action under this Agreement taken by the Underwriters jointly will be binding upon all the Underwriters. In all dealings under this Agreement, the Representative shall act on behalf of each of the Underwriters and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representative.

ANNEX I

          Pursuant to Section 6(f) of the Underwriting Agreement, the accountants shall furnish letters to the Underwriters to the effect that:

     (i) They are an independent registered public accounting firm with respect to the Guarantor and its subsidiaries within the meaning of the Securities Act and the applicable published rules and regulations thereunder adopted by the Securities and Exchange Commission (the “SEC”) and the Public Company Accounting Oversight Board (United States) (the “PCAOB”);

     (ii) In their opinion, the financial statements and any supplementary financial information and schedules (and, if applicable, financial forecasts and/or pro forma financial information) audited or examined by them and included or incorporated by reference in the Registration Statement or the Prospectus comply as to form in all material respects with the applicable accounting requirements of the Securities Act or the Exchange Act, as applicable, and the related published rules and regulations thereunder; and, if applicable, they have made a review in accordance with standards established by the American Institute of Certified Public Accountants of the consolidated interim financial statements, selected financial data, pro forma financial information, financial forecasts and/or condensed financial statements derived from audited financial statements of the Guarantor for the periods specified in such letter, as indicated in their reports thereon, copies of which have been furnished to the Underwriters;

     (iii) They have made a review in accordance with standards established by the American Institute of Certified Public Accountants of the unaudited condensed consolidated statements of income, consolidated balance sheets and consolidated statements of cash flows included in the Prospectus and/or included in the Guarantor’s Quarterly Report(s) on Form 10-Q covering periods after the latest full fiscal year and incorporated by reference into the Prospectus as indicated in their reports thereon, copies of which have been furnished to the Underwriters; and on the basis of specified procedures including inquiries of officials of the Guarantor who have responsibility for financial and accounting matters regarding whether the unaudited condensed consolidated financial statements referred to in paragraph (vi)(A)(i) below comply as to form in all material respects with the applicable accounting requirements of the Securities Act and the Exchange Act and the related published rules and regulations, nothing came to their attention that caused them to believe that the unaudited condensed consolidated financial statements do not comply as to form in all material respects with the applicable accounting requirements of the Securities Act and the Exchange Act and the related published rules and regulations;

     (iv) The unaudited selected financial information with respect to the consolidated results of operations and financial position of the Guarantor for the five most recent fiscal years included in the Prospectus and/or included or incorporated by

reference in Item 6 of the Guarantor’s Annual Report on Form 10-K for the most recent fiscal year agrees with the corresponding amounts (after restatement where applicable) in the audited consolidated financial statements for such five fiscal years which were included or incorporated by reference in the Guarantor’s Annual Reports on Form 10-K for such fiscal years;

     (v) They have compared the information in the Prospectus under selected captions with the disclosure requirements of Regulation S-K and on the basis of limited procedures specified in such letter nothing came to their attention as a result of the foregoing procedures that caused them to believe that this information does not conform in all material respects with the disclosure requirements of Items 301, 302, 402 and 503(d), respectively, of Regulation S-K;

     (vi) On the basis of limited procedures, not constituting an examination in accordance with generally accepted auditing standards, consisting of a reading of the unaudited financial statements and other information referred to below, a reading of the latest available interim financial statements of the Guarantor and its subsidiaries, inspection of the minute books of the Guarantor and its subsidiaries since the date of the latest audited financial statements included or incorporated by reference in the Prospectus, inquiries of officials of the Guarantor and its subsidiaries responsible for financial and accounting matters and such other inquiries and procedures as may be specified in such letter, nothing came to their attention that caused them to believe that:

     (A) (i) the unaudited consolidated statements of income, consolidated balance sheets and consolidated statements of cash flows included or incorporated by reference in the Company’s Quarterly Reports on Form 10-Q incorporated by reference in the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the related published rules and regulations, or (ii) any material modifications should be made to the unaudited consolidated statements of income, consolidated balance sheets and consolidated statements of cash flows included or incorporated by reference in the Guarantor’s Quarterly Report(s) on Form 10-Q incorporated by reference in the Prospectus for them to be in conformity with generally accepted accounting principles;

     (B) any other unaudited income statement data and balance sheet items included in the Prospectus do not agree with the corresponding items in the unaudited consolidated financial statements from which such data and items were derived, and any such unaudited data and items were not determined on a basis substantially consistent with the basis for the corresponding amounts in the audited consolidated financial statements included or incorporated by reference in the Guarantor’s Annual Report on Form 10-K for the most recent fiscal year;

     (C) the unaudited financial statements which were not included in the Prospectus but from which were derived the unaudited condensed financial statements referred to in clause (A) and any unaudited income statement data and

balance sheet items included in the Prospectus and referred to in clause (B) were not determined on a basis substantially consistent with the basis for the audited financial statements included or incorporated by reference in the Guarantor’s Annual Report on Form 10-K for the most recent fiscal year;

     (D) any unaudited pro forma consolidated condensed financial statements included or incorporated by reference in the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Securities Act and the published rules and regulations thereunder or the pro forma adjustments have not been properly applied to the historical amounts in the compilation of those statements;

     (E) as of a specified date not more than five days prior to the date of such letter, there have been any decreases in interest-bearing deposits, non-interest bearing deposits, total deposits or stockholders’ equity, or in other items specified by the Representative, or any increases in long-term borrowings, or in other items specified by the Representative, in each case as compared with amounts shown in the latest balance sheet included or incorporated by reference in the Prospectus, except in each case for changes, increases or decreases which the Prospectus discloses have occurred or may occur or which are described in such letter; and

     (F) for the period from the date of the latest financial statements included or incorporated by reference in the Prospectus to the specified date referred to in clause (E) there were any decreases in net interest income or net income, or other items specified by the Representative, or any increases in any items specified by the Representative, in each case as compared with the comparable period of the preceding year and with any other period of corresponding length specified by the Representative, except in each case for increases or decreases which the Prospectus discloses have occurred or may occur or which are described in such letter; and

     (vii) In addition to the examination or audit referred to in their report(s) included or incorporated by reference in the Prospectus and the limited procedures, inspection of minute books, inquiries and other procedures referred to in paragraphs (iii) and (vi) above, they have carried out certain specified procedures, not constituting an examination or audit in accordance with generally accepted auditing standards, with respect to certain amounts, percentages and financial information specified by the Representative which are derived from the general accounting records of the Guarantor and its subsidiaries, which appear in the Prospectus (excluding documents incorporated by reference) or in Part II of, or in exhibits and schedules to, the Registration Statement specified by the Representative or in documents incorporated by reference in the Prospectus specified by the Representative, and have compared certain of such amounts, percentages and financial information with the accounting records of the Guarantor and its subsidiaries and have found them to be in agreement.
