ARTICLE V

Capital Stock

The aggregate number of shares of all classes of capital stock which the Corporation has authority to issue is 42,000,000 of which 40,000,000 are to be shares of common stock, $1.00 par value per share, of which 1,000,000 are to be shares of serial preferred stock, $1.00 par value per share, and of which 1,000,000 shall be Class B serial preferred stock, $1.00 par value per share

The shares may be issued by the Corporation from time to time as approved by the board of directors of the

Corporation without the approval of the shareholders except as otherwise provided in this Article V or the rules of a national securities exchange or association, if applicable. The consideration for the issuance of the shares shall be paid to or received by the Corporation in full before their issuance and shall not be less than the par value per share. The consideration for the issuance of the shares shall be cash, services rendered, personal property (tangible or intangible), real property, leases of real property or any combination of the foregoing. In the absence of actual fraud in the transaction, the judgment of the board of directors as to the value of such consideration shall be conclusive. Upon payment of such consideration such shares shall be deemed to be fully paid and nonassessable. In the case of a stock dividend, the part of the surplus of the Corporation which is transferred to stated capital upon the issuance of shares as a stock dividend shall be deemed to be the consideration for their issuance.

A description of the different classes and series (if any) of the Corporation’s capital stock, and a statement of the relative powers, designations, preferences and rights of the shares of each class and series (if any) of capital stock, and the qualifications, limitations or restrictions thereof, are as follows:

A. Common Stock. Except as provided in this Certificate of Incorporation, the holders of the common stock shall exclusively possess all voting power. Each holder of shares of common stock shall be entitled to one vote for each share held by such holders.

Whenever there shall have been paid, or declared and set aside for payment, to the holders of the outstanding shares of any class of stock having preference over the common stock as to the payment of dividends, the full amount of dividends and sinking fund or retirement fund or other retirement payments, if any, to which such holders are respectively entitled in preference to the common stock, then dividends may be paid on the common stock, and on any class or series of stock entitled to participate therewith as to dividends, out of any assets legally available for the payment of dividends, but only when and as declared by the board of directors of the Corporation.

In the event of any liquidation, dissolution or winding up of the Corporation, after there shall have been paid, or declared and set aside for payment, to the holders of the outstanding shares of any class having preference over the common stock in any such event, the full preferential amounts to which they are respectively entitled, the holders of the common stock and of any class or series of stock entitled to participate therewith, in whole or in part, as to distribution of assets shall be entitled, after payment or provision for payment of all debts and liabilities of the Corporation, to receive the remaining assets of the Corporation available for distribution, in cash or in kind.

B. Serial Preferred Stock. Except as provided in this Certificate of Incorporation, the board of directors of the Corporation is authorized, by resolution or resolutions from time to time adopted, to provide for the issuance of serial preferred stock in series and to fix and state the powers, designations, preferences and relative, participating, optional or other special rights of the shares of each such series, and the qualifications, limitations or restrictions thereof, including, but not limited to, determination of any of the following:

	(7)		whether the shares of such series shall be convertible into, or exchangeable for, shares of any other class or classes or any other series of the same or any other class of classes of stock of the Corporation and, if so convertible or exchangeable, the conversion price or prices, or the rate or rates of exchange, and the adjustments thereof, if any, at which such conversion or exchange may be made, and any other terms and conditions of such conversion or exchange;

	(8)		the subscription or purchase price and form of consideration for which the shares of such series shall be issued; and

	(9)		whether the shares of such series which are redeemed or converted shall have the status of authorized but unissued shares of serial preferred stock and whether such shares may be reissued as shares of the same or any other series of serial preferred stock.

Each share of each series of serial preferred stock shall have the same relative powers, preferences and rights as, and shall be identical in all respects with, all the other shares of the Corporation of the same series.

C. Class B Serial Preferred Stock. Except as provided in this Certificate of Incorporation, the board of directors of the Corporation is authorized, by resolution or resolutions from time to time adopted, to provide for the issuance of Class B serial preferred stock in one or more series, and to fix and state the powers, designations, preferences and relative, participating, optional or other special rights of the shares of each series, and the qualifications, limitations and restrictions thereof, including , but not limited to, determination of any of the following:

	(5)		the amount or amounts payable upon the shares of such series in the event of voluntary or involuntary liquidation, dissolution or winding up of the Corporation;

	(6)		whether the shares of such series shall be entitled to the benefits of a sinking or retirement fund to be applied to the purchase or redemption of such shares, and, if so entitled, the amount of such fund and the manner of its application, including the price or prices at which such shares may be redeemed or purchased through the application of such funds;

	(7)		whether the shares of such series shall be convertible into, or exchangeable for, shares of any other class or classes or into any other series of the same or any other class or classes of stock of the Corporation and, if so convertible or exchangeable, the conversion price or prices, or the rate or rates of exchange, and the adjustments thereof, if any, at which such conversion or exchange may be made, and any other terms and conditions of such conversion or exchange;

	(8)		the subscription or purchase price and the form of consideration for which the shares of such series shall be issued; and

	(9)		whether the shares of such series which are redeemed or converted shall have the status of authorized but unissued shares of Class B serial preferred stock and whether such shares may be reissued as shares of the same or any other series of Class B serial preferred stock.

Each share of each series of Class B serial preferred stock shall have the same relative powers, preferences and rights as, and shall be identical in all respects with, all of the other shares of the Corporation of the same series.

Notwithstanding anything to the contrary contained herein or in any resolution of the board of directors providing for the issuance of any series of Class B serial preferred stock, all shares of Class B serial preferred stock, of any series, shall rank junior in respect of the payment of dividends and payments to be received upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation to all shares of the Corporation’s 9.20% Redeemable Cumulative Preferred Stock, Series A, or any class or series of capital stock ranking prior to or on a parity with such 9.20% Redeemable Cumulative Preferred Stock, Series A.

Except as may be expressly provided in the resolution of the board of directors providing for the issuance of any series of Class B serial preferred stock, the number of shares of Class B serial preferred stock authorized hereby may be increased or decreased, but not below the number of shares of all series of Class B serial preferred stock outstanding as of the date of such decrease, upon the vote of a majority of the shares of common stock and any other class entitled to vote with the common stock generally in respect of amendments hereof, and without the separate vote or approval of the Class B serial preferred stock, or of any series of Class B serial preferred stock, voting separately as a class.

ARTICLE VI

The Corporation may from time to time, pursuant to authorization by the board of directors of the Corporation and without action by the shareholders, purchase or otherwise acquire shares of any class, bonds, debentures, notes, scrip, warrants, obligations, evidences of indebtedness, or other securities of the Corporation in such manner, upon such terms, and in such amounts as the board of directors shall determine; subject, however, to such limitations or restrictions, if any, as are contained in the express terms of any class of shares of the Corporation outstanding at the time of the purchase or acquisition in question or as are imposed by law.

ARTICLE VIII

Meetings of Shareholders; Cumulative Voting

A. Notwithstanding any other provision of this Certificate of Incorporation or the bylaws of the Corporation, no action required to be taken or which may be taken at any annual or special meeting of shareholders of the Corporation may be taken without a meeting, and the power of shareholders to consent in writing, without a meeting, to the taking of any action is specifically denied.

B. Special meetings of the shareholders of the Corporation for any purpose or purposes may be called at any time by the board of directors of the Corporation, or by a committee of the board of directors which has been duly designated by the board of directors and whose powers and authorities, as provided in a resolution of the board of directors or in the bylaws of the Corporation, include the power and authority to call such meetings, but such special meetings may not be called by any other person or persons.

C. There shall be cumulative voting by shareholders of any class or series in the election of directors of the Corporation. At all times each holder of common stock of the Corporation shall be entitle to one(1) vote for each share of such stock standing in his name on the books of the Corporation. At all elections of Directors of the Corporation, the number of votes which (except for this provision) he would then be entitled to cast for the election of Directors with respect to his shares, multiplied by the number of Directors upon whose election he is then entitled to vote, and he may cast all or such votes for a single candidate or may distribute them among some or all of the candidates as he may see fit.

D. Meetings of shareholders may be held within or without the State of Oklahoma, as the bylaws may provide.

ARTICLE IX

Notice for Nominations and Proposals

A. Nominations for the election of directors and proposals for any new business to be taken up at any annual or special meeting of shareholders may be made by the board of directors of the Corporation or by any shareholder of the Corporation entitled to vote generally in the election of directors. In order for a shareholder of the Corporation to make any such nominations and/or proposals, he or she shall give notice thereof in writing, delivered or mailed by first class United States mail, postage prepaid, to the Secretary of the Corporation not less than 30 days nor more than 60 days prior to any such meeting; provided, however, that if less than 40 days’ notice of the meeting is given to shareholders, such written notice shall be delivered or mailed, as prescribed, to the Secretary of the Corporation not later than the close of the tenth day following the day on which notice of the meeting was mailed to shareholders. Each such notice given by a shareholder with respect to nominations for the election of directors shall set forth (i) the name, age, business address and, if known, residence address of each nominee proposed in such notice, (ii) the principal occupation or employment of each such nominee, and (iii) the number of shares of stock of the Corporation which are beneficially owned by each such nominee. In addition, the shareholder making such nomination shall promptly provide any other information reasonably requested by the Corporation.

B. Each such notice given by a shareholder to the Secretary with respect to business proposals to bring before a meeting shall set forth in writing as to each matter: (i) a brief description of the business desired to be brought before the meeting and the reasons for conducting such business at the meeting; (ii) the name and address, as they appear on the Corporation’s books, of the shareholder proposing such business; (iii) the class and number of shares of the Corporation which are beneficially owned by the shareholder; and (iv) any material interest of the shareholder in such business. Notwithstanding anything in this Certificate of Incorporation to the contrary, no business shall be conducted at the meeting except in accordance with the procedures set forth in this Article IX.

C. The Chairman of the annual or special meeting of shareholders may, if the facts warrant, determine and declare to such meeting that a nomination or proposal was not made in accordance with the foregoing procedure, and, if he should so determine, he shall so declare to the meeting, and the defective nomination or proposal shall be disregarded and laid over for action at the next succeeding adjourned, special or annual meeting of the shareholders taking place thirty days or more thereafter. This provision shall not require the holding of any adjourned or special meeting of shareholders for the purpose of considering such defective nomination or proposal.

ARTICLE X

Directors

The number of directors of the Corporation shall be such number, not less than three nor more than twenty-one (exclusive of directors, if any, to be elected by holders of preferred stock of the Corporation, voting separately as a class), as shall be provided from time to time in or in accordance with the bylaws, provided that no decrease in the number of directors shall have the effect of shortening the term of any incumbent director, and provided further that no action shall be taken to decrease or increase the number of directors from time to time unless at least two-thirds of the directors then in office shall concur in said action. Vacancies in the board of directors of the Corporation, however caused, and newly created directorships shall be filled by a vote of two-thirds of the directors then in office, whether or not a quorum, and any director so chosen shall hold office for a term expiring at the annual meeting of shareholders and when the director’s successor is elected and qualified. Commencing with the 2009 annual meeting of shareholders, directors shall be elected annually for terms of one year and shall hold office until the next succeeding annual meeting and their successors are elected and qualified. Directors elected at the 2006 annual meeting of shareholders shall hold office until the 2009 annual meeting of shareholders; directors elected at the 2007 annual meeting of shareholders shall hold office until the 2010 annual meeting of shareholders; and directors elected at the 2008 annual meeting of shareholders shall hold office until the 2011 annual meeting of shareholders.

Whenever the holders of any one or more series of preferred stock of the Corporation shall have the right, voting separately as a class, to elect one or more directors of the Corporation, the board of directors shall consist of said directors so elected in addition to the number of directors fixed as provided in this Article X. Notwithstanding the foregoing, and except as otherwise may be required by law, whenever the holders of any one or more series of preferred stock of the Corporation shall have the right, voting separately as a class, to elect one or more directors of the Corporation, the terms of the director or directors elected by such holders shall expire at the next succeeding annual meeting of shareholders.

ARTICLE XI

Removal of Directors

Notwithstanding any other provision of this Certificate of Incorporation or the bylaws of the Corporation, any director or the entire board of directors of the Corporation may be removed at any time, but only for cause and only by the affirmative vote of the holders of at least 80% of the outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors (considered for this purpose as one class) cast at a meeting of the shareholders called for that purpose. Notwithstanding the foregoing, whenever the holders of any one or more series of preferred stock of the Corporation shall have the right, voting separately as a class, to elect one or more directors of the Corporation, the preceding provisions of this Article XI shall not apply with respect to the director or directors elected by such holders of preferred stock.

For purposes of this Article XII, “substantially all of the assets” shall mean assets having a fair market value or book value, whichever is greater, of twenty-five percent (25%) or more of the total assets of the Corporation as reflected on a balance sheet of the Corporation as of a date no earlier than forty-five (45) days prior to any acquisition of such assets.

C. For the purposes of this Article XIII the following definitions apply:

(1) The term “Related Person” shall mean and include (a) any individual, corporation, partnership or other person or entity which together with its “affiliates” (as that term is defined in Rule 12b-2 of the General Rules and Regulations under the Securities Exchange Act of 1934), “beneficially owns” (as that term is defined in Rule 13d-3 of the General Rules and Regulations under the Securities Exchange Act of 1934) in the aggregate 10% or more of the outstanding shares of the common stock of the Corporation; and (b) any “affiliate” (as that term is defined in Rule 12b-2 under the Securities Exchange Act of 1934) of any such individual, corporation, partnership or other person or entity.

ARTICLE XIV

Evaluation of Business Combinations

In connection with the exercise of its judgment in determining what is in the best interests of the Corporation and of the shareholders, when evaluating a Business Combination (as defined in Article XIII) or a tender or exchange offer, the board of directors of the Corporation may, in addition to considering the adequacy of the amount to be paid in connection with any such transaction, consider all of the following factors and any other factors which it deems relevant; (i) the social and economic effects of the transaction on the Corporation and its subsidiaries, employees, depositors, loan and other customers, creditors and other elements of the communities in which the Corporation and its subsidiaries operate or are located; (ii) the business and financial condition and earnings prospects of the acquiring person or entity, including, but not limited to, debt service and other existing financial obligations, financial obligations to be incurred in connection with the acquisition and other likely financial obligations of the acquiring person or entity and the possible effect of such conditions upon the Corporation and its subsidiaries and the other elements of the communities in which the Corporation and its subsidiaries operate or are located; and (iii) the competence, experience, and integrity of the acquiring person or entity and its or their management.

ARTICLE XV

Indemnification

A. Persons. The Corporation shall indemnify, to the extent provided in paragraphs B, D or F:

(1) any person who is or was a director, officer, employee, or agent of the Corporation; and

(2) any person who serves or served at the Corporation’s request as a director, officer, employee, agent, partner or trustee of another corporation, partnership, joint venture, trust or other enterprise.

B. Extent — Derivative Suits. In case of a threatened, pending or completed action or suit by or in the right of the Corporation against a person named in paragraph A by reason of his holding a position named in paragraph A, the Corporation shall indemnify him if he satisfies the standard in paragraph C, for expenses (including attorneys’ fees) actually and reasonably incurred by him in connection with the defense or settlement of the action or suit.

C. Standard — Derivative Suits. In case of a threatened, pending or completed action or suit by or in the right of the Corporation, a person named in paragraph A shall be indemnified only if:

(1) he is successful on the merits or otherwise; or

(2) he acted in good faith in the transaction which is the subject of the action or suit, and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Corporation, including, but not limited to, the taking of any and all actions in connection with the Corporation’s response to any tender offer or any offer or proposal of another party to engage in a Business Combination (as defined in Article XIII) not approved by the board of directors. However, he shall not be indemnified in respect of any claim, issue or matter as to which he has been adjudged liable to the Corporation unless (and only to the extent that) the court in which the action or suit was brought shall determine, upon application, that despite the adjudication but in view of all the circumstances, he is fairly and reasonably entitled to indemnity for such expenses as the court shall deem proper.

D. Extent — Nonderivative Suits. In case of a threatened, pending or completed suit, action or proceeding (whether civil, criminal, administrative or investigative), other than a suit by or in the right of the Corporation, together hereafter referred to as a nonderivative suit, against a person named in paragraph A by reason of his holding a position named in paragraph A, the Corporation shall indemnify him if he satisfies the standard in paragraph E, for amounts actually and reasonably incurred by him in connection with the defense or settlement of the nonderivative suit, including, but not limited to (i) expenses (including attorneys’ fees), (ii) amounts paid in settlement, (iii) judgments, and (iv) fines.

E. Standard — Nonderivative Suits. In case of a nonderivative suit, a person named in paragraph A shall be indemnified if:

(1) he is successful on the merits or otherwise; or

(2) he acted in good faith in the transaction which is the subject of the nonderivative suit and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Corporation, including, but not limited to, the taking of any and all actions in connection with the Corporation’s response to any tender offer or any offer or proposal of another party to engage in a Business Combination (as defined in Article XIII) not approved by the board of directors, and, with respect to any criminal action or proceeding, he had no reasonable cause to believe his conduct was unlawful. The termination of a nonderivative suit by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent shall not, of itself, create a presumption that the person failed to satisfy the standard of this subparagraph E(2).

F. Determination That Standard Has Been Met. A determination that the standard of paragraph C or E has been satisfied may be made by a court. Or, except as stated in subparagraph C(2) (second sentence), the determination may be made by:

(1) the board of directors by a majority vote of a quorum consisting of directors of the Corporation who were not parties to the action, suit or proceeding; or

(2) independent legal counsel (appointed by a majority of the disinterested directors of the Corporation, whether or not a quorum) in a written opinion; or

(3) the shareholders of the Corporation.

G. Proration. Anyone making a determination under paragraph F may determine that a person has met the standard as to some matters but not as to others, and may reasonably prorate amounts to be indemnified.

H. Advance Payment. The Corporation shall pay in advance any expenses (including attorneys’ fees) which may become subject to indemnification under paragraphs A through G if:

(1) the board of directors authorizes the specific payment; and

(2) the person receiving the payment undertakes in writing to repay the same if it is ultimately determined that he is not entitled to indemnification by the Corporation under paragraphs A through G.

I. Nonexclusive. The indemnification and advance payment of expenses provided by paragraphs A through H shall not be exclusive of any other rights to which a person may be entitled by law, bylaw, agreement, vote of shareholders or disinterested directors, or otherwise.

J. Continuation. The indemnification provided by this Article XV shall be deemed to be a contract between the Corporation and the persons entitled to indemnification thereunder, and any repeal or modification of this Article XV shall not affect any rights or obligations then existing with respect to any state of facts then or theretofore existing or any action, suit or proceeding theretofore or thereafter brought based in whole or in part upon any such state of facts. The indemnification and advance payment provided by paragraphs A through H shall continue as to a person who has ceased to hold a position named in paragraph A and shall inure to his heirs, executors and administrators.

K. Insurance. The Corporation may purchase and maintain insurance on behalf of any person who holds or who has held any position named in paragraph A, against any liability incurred by him in any such position, or arising out of his status as such, whether or not the Corporation would have power to indemnify him against such liability under paragraphs A through H.

L. Savings Clause. If this Article XV or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each director, officer, employee, and agent of the Corporation or person who serves or served at the Corporation’s request as a director, officer, employee, agent, partner or trustee of another corporation, partnership, joint venture, trust or other enterprise as to costs, charges, and expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement with respect to any action, suit, or proceeding, whether civil, criminal, administrative, or investigative, including an action by or in the right of the Corporation to the full extent permitted by any applicable portion of this Article XV that shall not have been invalidated and to the full extent permitted by applicable law.

ARTICLE XVI

Limitations on Directors’ Liability

A director of the Corporation shall not be personally liable to the Corporation or its shareholders for monetary damages for breach of fiduciary duty as a director, except: (i) for any breach of the director’s duty of loyalty to the

Corporation or its shareholders, (ii) for acts or omissions that are not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) under Section 1053 or of the Oklahoma General Corporation Act; or (iv) for any transaction from which the director derived an improper personal benefit. If the Oklahoma General Corporation Act is amended after the date of filing of this Certificate of Incorporation to further eliminate or limit the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the Oklahoma General Corporation Act, as so amended.

Any repeal or modification of the foregoing paragraph by the shareholders of the Corporation shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification.

ARTICLE XVII

Section 3. Dividends.

(a) Rate. Holders of Designated Preferred Stock shall be entitled to receive, on each share of Designated Preferred Stock if, as and when declared by the Board of Directors or any duly authorized committee of the Board of Directors, but only out of assets legally available therefor, cumulative cash dividends with respect to each Dividend Period (as defined below) at a rate per annum equal to the Applicable Dividend Rate on (i) the Liquidation Amount per share of Designated Preferred Stock and (ii) the amount of accrued and unpaid dividends for any prior Dividend Period on such share of Designated Preferred Stock, if any. Such dividends shall begin to accrue and be cumulative from the Original Issue Date, shall compound on each subsequent Dividend Payment Date (i.e., no dividends shall accrue on other dividends unless and until the first Dividend Payment Date for such other dividends has passed without such other dividends having been paid on such date) and shall be payable quarterly in arrears on each Dividend Payment Date, commencing with the first such Dividend Payment Date to occur at least 20 calendar days after the Original Issue Date. In the event that any Dividend Payment Date would otherwise fall on a day that is not a Business Day, the dividend payment due on that date will be postponed to the next day that is a Business Day and no additional dividends will accrue as a result of that postponement. The period from and including any Dividend Payment Date to, but

A-2

UST Sequence Number: 114

excluding, the next Dividend Payment Date is a “Dividend Period”, provided that the initial Dividend Period shall be the period from and including the Original Issue Date to, but excluding, the next Dividend Payment Date.

Dividends that are payable on Designated Preferred Stock in respect of any Dividend Period shall be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of dividends payable on Designated Preferred Stock on any date prior to the end of a Dividend Period, and for the initial Dividend Period, shall be computed on the basis of a 360-day year consisting of twelve 30-day months, and actual days elapsed over a 30-day month.

Dividends that are payable on Designated Preferred Stock on any Dividend Payment Date will be payable to holders of record of Designated Preferred Stock as they appear on the stock register of the Corporation on the applicable record date, which shall be the 15th calendar day immediately preceding such Dividend Payment Date or such other record date fixed by the Board of Directors or any duly authorized committee of the Board of Directors that is not more than 60 nor less than 10 days prior to such Dividend Payment Date (each, a “Dividend Record Date”). Any such day that is a Dividend Record Date shall be a Dividend Record Date whether or not such day is a Business Day.

Holders of Designated Preferred Stock shall not be entitled to any dividends, whether payable in cash, securities or other property, other than dividends (if any) declared and payable on Designated Preferred Stock as specified in this Section 3 (subject to the other provisions of the Certificate of Designations).

(b) Priority of Dividends. So long as any share of Designated Preferred Stock remains outstanding, no dividend or distribution shall be declared or paid on the Common Stock or any other shares of Junior Stock (other than dividends payable solely in shares of Common Stock) or Parity Stock, subject to the immediately following paragraph in the case of Parity Stock, and no Common Stock, Junior Stock or Parity Stock shall be, directly or indirectly, purchased, redeemed or otherwise acquired for consideration by the Corporation or any of its subsidiaries unless all accrued and unpaid dividends for all past Dividend Periods, including the latest completed Dividend Period (including, if applicable as provided in Section 3(a) above, dividends on such amount), on all outstanding shares of Designated Preferred Stock have been or are contemporaneously declared and paid in full (or have been declared and a sum sufficient for the payment thereof has been set aside for the benefit of the holders of shares of Designated Preferred Stock on the applicable record date). The foregoing limitation shall not apply to (i) redemptions, purchases or other acquisitions of shares of Common Stock or other Junior Stock in connection with the administration of any employee benefit plan in the ordinary course of business (including purchases to offset the Share Dilution Amount (as defined below) pursuant to a publicly announced repurchase plan) and consistent with past practice, provided that any purchases to offset the Share Dilution Amount shall in no event exceed the Share Dilution Amount; (ii) purchases or other acquisitions by a broker-dealer subsidiary of the Corporation solely for the purpose of market-making, stabilization or customer facilitation transactions in Junior Stock or Parity Stock in the ordinary course of its business; (iii) purchases by a broker-dealer subsidiary of the Corporation of capital stock of the Corporation for resale pursuant to an offering by the Corporation of such capital stock underwritten by such broker-dealer subsidiary; (iv) any dividends or distributions of rights or Junior Stock in connection with a stockholders’

A-3

UST Sequence Number: 114

rights plan or any redemption or repurchase of rights pursuant to any stockholders’ rights plan; (v) the acquisition by the Corporation or any of its subsidiaries of record ownership in Junior Stock or Parity Stock for the beneficial ownership of any other persons (other than the Corporation or any of its subsidiaries), including as trustees or custodians; and (vi) the exchange or conversion of Junior Stock for or into other Junior Stock or of Parity Stock for or into other Parity Stock (with the same or lesser aggregate liquidation amount) or Junior Stock, in each case, solely to the extent required pursuant to binding contractual agreements entered into prior to the Signing Date or any subsequent agreement for the accelerated exercise, settlement or exchange thereof for Common Stock. “Share Dilution Amount” means the increase in the number of diluted shares outstanding (determined in accordance with generally accepted accounting principles in the United States, and as measured from the date of the Corporation’s consolidated financial statements most recently filed with the Securities and Exchange Commission prior to the Original Issue Date) resulting from the grant, vesting or exercise of equity-based compensation to employees and equitably adjusted for any stock split, stock dividend, reverse stock split, reclassification or similar transaction.

When dividends are not paid (or declared and a sum sufficient for payment thereof set aside for the benefit of the holders thereof on the applicable record date) on any Dividend Payment Date (or, in the case of Parity Stock having dividend payment dates different from the Dividend Payment Dates, on a dividend payment date falling within a Dividend Period related to such Dividend Payment Date) in full upon Designated Preferred Stock and any shares of Parity Stock, all dividends declared on Designated Preferred Stock and all such Parity Stock and payable on such Dividend Payment Date (or, in the case of Parity Stock having dividend payment dates different from the Dividend Payment Dates, on a dividend payment date falling within the Dividend Period related to such Dividend Payment Date) shall be declared pro rata so that the respective amounts of such dividends declared shall bear the same ratio to each other as all accrued and unpaid dividends per share on the shares of Designated Preferred Stock (including, if applicable as provided in Section 3(a) above, dividends on such amount) and all Parity Stock payable on such Dividend Payment Date (or, in the case of Parity Stock having dividend payment dates different from the Dividend Payment Dates, on a dividend payment date falling within the Dividend Period related to such Dividend Payment Date) (subject to their having been declared by the Board of Directors or a duly authorized committee of the Board of Directors out of legally available funds and including, in the case of Parity Stock that bears cumulative dividends, all accrued but unpaid dividends) bear to each other. If the Board of Directors or a duly authorized committee of the Board of Directors determines not to pay any dividend or a full dividend on a Dividend Payment Date, the Corporation will provide written notice to the holders of Designated Preferred Stock prior to such Dividend Payment Date.

Subject to the foregoing, and not otherwise, such dividends (payable in cash, securities or other property) as may be determined by the Board of Directors or any duly authorized committee of the Board of Directors may be declared and paid on any securities, including Common Stock and other Junior Stock, from time to time out of any funds legally available for such payment, and holders of Designated Preferred Stock shall not be entitled to participate in any such dividends.

Section 4. Liquidation Rights.

A-4

UST Sequence Number: 114

(a) Voluntary or Involuntary Liquidation. In the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, holders of Designated Preferred Stock shall be entitled to receive for each share of Designated Preferred Stock, out of the assets of the Corporation or proceeds thereof (whether capital or surplus) available for distribution to stockholders of the Corporation, subject to the rights of any creditors of the Corporation, before any distribution of such assets or proceeds is made to or set aside for the holders of Common Stock and any other stock of the Corporation ranking junior to Designated Preferred Stock as to such distribution, payment in full in an amount equal to the sum of (i) the Liquidation Amount per share and (ii) the amount of any accrued and unpaid dividends (including, if applicable as provided in Section 3(a) above, dividends on such amount), whether or not declared, to the date of payment (such amounts collectively, the “Liquidation Preference”).

(b) Partial Payment. If in any distribution described in Section 4(a) above the assets of the Corporation or proceeds thereof are not sufficient to pay in full the amounts payable with respect to all outstanding shares of Designated Preferred Stock and the corresponding amounts payable with respect of any other stock of the Corporation ranking equally with Designated Preferred Stock as to such distribution, holders of Designated Preferred Stock and the holders of such other stock shall share ratably in any such distribution in proportion to the full respective distributions to which they are entitled.

(c) Residual Distributions. If the Liquidation Preference has been paid in full to all holders of Designated Preferred Stock and the corresponding amounts payable with respect of any other stock of the Corporation ranking equally with Designated Preferred Stock as to such distribution has been paid in full, the holders of other stock of the Corporation shall be entitled to receive all remaining assets of the Corporation (or proceeds thereof) according to their respective rights and preferences.

(d) Merger, Consolidation and Sale of Assets Not Liquidation. For purposes of this Section 4, the merger or consolidation of the Corporation with any other corporation or other entity, including a merger or consolidation in which the holders of Designated Preferred Stock receive cash, securities or other property for their shares, or the sale, lease or exchange (for cash, securities or other property) of all or substantially all of the assets of the Corporation, shall not constitute a liquidation, dissolution or winding up of the Corporation.

Section 5. Redemption.

(a) Optional Redemption. Except as provided below, the Designated Preferred Stock may not be redeemed prior to the first Dividend Payment Date falling on or after the third anniversary of the Original Issue Date. On or after the first Dividend Payment Date falling on or after the third anniversary of the Original Issue Date, the Corporation, at its option, subject to the approval of the Appropriate Federal Banking Agency, may redeem, in whole or in part, at any time and from time to time, out of funds legally available therefor, the shares of Designated Preferred Stock at the time outstanding, upon notice given as provided in Section 5(c) below, at a redemption price equal to the sum of (i) the Liquidation Amount per share and (ii) except as otherwise provided below, any accrued and unpaid dividends (including, if applicable as

A-5

UST Sequence Number: 114

provided in Section 3(a) above, dividends on such amount) (regardless of whether any dividends are actually declared) to, but excluding, the date fixed for redemption.

Notwithstanding the foregoing, prior to the first Dividend Payment Date falling on or after the third anniversary of the Original Issue Date, the Corporation, at its option, subject to the approval of the Appropriate Federal Banking Agency, may redeem, in whole or in part, at any time and from time to time, the shares of Designated Preferred Stock at the time outstanding, upon notice given as provided in Section 5(c) below, at a redemption price equal to the sum of (i) the Liquidation Amount per share and (ii) except as otherwise provided below, any accrued and unpaid dividends (including, if applicable as provided in Section 3(a) above, dividends on such amount) (regardless of whether any dividends are actually declared) to, but excluding, the date fixed for redemption; provided that (x) the Corporation (or any successor by Business Combination) has received aggregate gross proceeds of not less than the Minimum Amount (plus the “Minimum Amount” as defined in the relevant certificate of designations for each other outstanding series of preferred stock of such successor that was originally issued to the United States Department of the Treasury (the “Successor Preferred Stock”) in connection with the Troubled Asset Relief Program Capital Purchase Program) from one or more Qualified Equity Offerings (including Qualified Equity Offerings of such successor), and (y) the aggregate redemption price of the Designated Preferred Stock (and any Successor Preferred Stock) redeemed pursuant to this paragraph may not exceed the aggregate net cash proceeds received by the Corporation (or any successor by Business Combination) from such Qualified Equity Offerings (including Qualified Equity Offerings of such successor).

The redemption price for any shares of Designated Preferred Stock shall be payable on the redemption date to the holder of such shares against surrender of the certificate(s) evidencing such shares to the Corporation or its agent. Any declared but unpaid dividends payable on a redemption date that occurs subsequent to the Dividend Record Date for a Dividend Period shall not be paid to the holder entitled to receive the redemption price on the redemption date, but rather shall be paid to the holder of record of the redeemed shares on such Dividend Record Date relating to the Dividend Payment Date as provided in Section 3 above.

(b) No Sinking Fund. The Designated Preferred Stock will not be subject to any mandatory redemption, sinking fund or other similar provisions. Holders of Designated Preferred Stock will have no right to require redemption or repurchase of any shares of Designated Preferred Stock.

(c) Notice of Redemption. Notice of every redemption of shares of Designated Preferred Stock shall be given by first class mail, postage prepaid, addressed to the holders of record of the shares to be redeemed at their respective last addresses appearing on the books of the Corporation. Such mailing shall be at least 30 days and not more than 60 days before the date fixed for redemption. Any notice mailed as provided in this Subsection shall be conclusively presumed to have been duly given, whether or not the holder receives such notice, but failure duly to give such notice by mail, or any defect in such notice or in the mailing thereof, to any holder of shares of Designated Preferred Stock designated for redemption shall not affect the validity of the proceedings for the redemption of any other shares of Designated Preferred Stock. Notwithstanding the foregoing, if shares of Designated Preferred Stock are issued in book-entry form through The Depository Trust Corporation or any other similar facility, notice of

A-6

UST Sequence Number: 114

redemption may be given to the holders of Designated Preferred Stock at such time and in any manner permitted by such facility. Each notice of redemption given to a holder shall state: (1) the redemption date; (2) the number of shares of Designated Preferred Stock to be redeemed and, if less than all the shares held by such holder are to be redeemed, the number of such shares to be redeemed from such holder; (3) the redemption price; and (4) the place or places where certificates for such shares are to be surrendered for payment of the redemption price.

(d) Partial Redemption. In case of any redemption of part of the shares of Designated Preferred Stock at the time outstanding, the shares to be redeemed shall be selected either pro rata or in such other manner as the Board of Directors or a duly authorized committee thereof may determine to be fair and equitable. Subject to the provisions hereof, the Board of Directors or a duly authorized committee thereof shall have full power and authority to prescribe the terms and conditions upon which shares of Designated Preferred Stock shall be redeemed from time to time. If fewer than all the shares represented by any certificate are redeemed, a new certificate shall be issued representing the unredeemed shares without charge to the holder thereof.

(e) Effectiveness of Redemption. If notice of redemption has been duly given and if on or before the redemption date specified in the notice all funds necessary for the redemption have been deposited by the Corporation, in trust for the pro rata benefit of the holders of the shares called for redemption, with a bank or trust company doing business in the Borough of Manhattan, The City of New York, and having a capital and surplus of at least $500 million and selected by the Board of Directors, so as to be and continue to be available solely therefor, then, notwithstanding that any certificate for any share so called for redemption has not been surrendered for cancellation, on and after the redemption date dividends shall cease to accrue on all shares so called for redemption, all shares so called for redemption shall no longer be deemed outstanding and all rights with respect to such shares shall forthwith on such redemption date cease and terminate, except only the right of the holders thereof to receive the amount payable on such redemption from such bank or trust company, without interest. Any funds unclaimed at the end of three years from the redemption date shall, to the extent permitted by law, be released to the Corporation, after which time the holders of the shares so called for redemption shall look only to the Corporation for payment of the redemption price of such shares.

(f) Status of Redeemed Shares. Shares of Designated Preferred Stock that are redeemed, repurchased or otherwise acquired by the Corporation shall revert to authorized but unissued shares of Preferred Stock (provided that any such cancelled shares of Designated Preferred Stock may be reissued only as shares of any series of Preferred Stock other than Designated Preferred Stock).

Section 6. Conversion. Holders of Designated Preferred Stock shares shall have no right to exchange or convert such shares into any other securities.

Section 7. Voting Rights.

(a) General. The holders of Designated Preferred Stock shall not have any voting rights except as set forth below or as otherwise from time to time required by law.

A-7

UST Sequence Number: 114

(b) Preferred Stock Directors. Whenever, at any time or times, dividends payable on the shares of Designated Preferred Stock have not been paid for an aggregate of six quarterly Dividend Periods or more, whether or not consecutive, the authorized number of directors of the Corporation shall automatically be increased by two and the holders of the Designated Preferred Stock shall have the right, with holders of shares of any one or more other classes or series of Voting Parity Stock outstanding at the time, voting together as a class, to elect two directors (hereinafter the “Preferred Directors” and each a “Preferred Director”) to fill such newly created directorships at the Corporation’s next annual meeting of stockholders (or at a special meeting called for that purpose prior to such next annual meeting) and at each subsequent annual meeting of stockholders until all accrued and unpaid dividends for all past Dividend Periods, including the latest completed Dividend Period (including, if applicable as provided in Section 3(a) above, dividends on such amount), on all outstanding shares of Designated Preferred Stock have been declared and paid in full at which time such right shall terminate with respect to the Designated Preferred Stock, except as herein or by law expressly provided, subject to revesting in the event of each and every subsequent default of the character above mentioned; provided that it shall be a qualification for election for any Preferred Director that the election of such Preferred Director shall not cause the Corporation to violate any corporate governance requirements of any securities exchange or other trading facility on which securities of the Corporation may then be listed or traded that listed or traded companies must have a majority of independent directors. Upon any termination of the right of the holders of shares of Designated Preferred Stock and Voting Parity Stock as a class to vote for directors as provided above, the Preferred Directors shall cease to be qualified as directors, the term of office of all Preferred Directors then in office shall terminate immediately and the authorized number of directors shall be reduced by the number of Preferred Directors elected pursuant hereto. Any Preferred Director may be removed at any time, with or without cause, and any vacancy created thereby may be filled, only by the affirmative vote of the holders a majority of the shares of Designated Preferred Stock at the time outstanding voting separately as a class together with the holders of shares of Voting Parity Stock, to the extent the voting rights of such holders described above are then exercisable. If the office of any Preferred Director becomes vacant for any reason other than removal from office as aforesaid, the remaining Preferred Director may choose a successor who shall hold office for the unexpired term in respect of which such vacancy occurred.

(c) Class Voting Rights as to Particular Matters. So long as any shares of Designated Preferred Stock are outstanding, in addition to any other vote or consent of stockholders required by law or by the Charter, the vote or consent of the holders of at least 66 2/3% of the shares of Designated Preferred Stock at the time outstanding, voting as a separate class, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, shall be necessary for effecting or validating:

(i) Authorization of Senior Stock. Any amendment or alteration of the Certificate of Designations for the Designated Preferred Stock or the Charter to authorize or create or increase the authorized amount of, or any issuance of, any shares of, or any securities convertible into or exchangeable or exercisable for shares of, any class or series of capital stock of the Corporation ranking senior to Designated Preferred Stock with respect to either or both the payment of dividends and/or the distribution of assets on any liquidation, dissolution or winding up of the Corporation;

A-8

UST Sequence Number: 114

(ii) Amendment of Designated Preferred Stock. Any amendment, alteration or repeal of any provision of the Certificate of Designations for the Designated Preferred Stock or the Charter (including, unless no vote on such merger or consolidation is required by Section 7(c)(iii) below, any amendment, alteration or repeal by means of a merger, consolidation or otherwise) so as to adversely affect the rights, preferences, privileges or voting powers of the Designated Preferred Stock; or

(iii) Share Exchanges, Reclassifications, Mergers and Consolidations. Any consummation of a binding share exchange or reclassification involving the Designated Preferred Stock, or of a merger or consolidation of the Corporation with another corporation or other entity, unless in each case (x) the shares of Designated Preferred Stock remain outstanding or, in the case of any such merger or consolidation with respect to which the Corporation is not the surviving or resulting entity, are converted into or exchanged for preference securities of the surviving or resulting entity or its ultimate parent, and (y) such shares remaining outstanding or such preference securities, as the case may be, have such rights, preferences, privileges and voting powers, and limitations and restrictions thereof, taken as a whole, as are not materially less favorable to the holders thereof than the rights, preferences, privileges and voting powers, and limitations and restrictions thereof, of Designated Preferred Stock immediately prior to such consummation, taken as a whole;

provided, however, that for all purposes of this Section 7(c), any increase in the amount of the authorized Preferred Stock, including any increase in the authorized amount of Designated Preferred Stock necessary to satisfy preemptive or similar rights granted by the Corporation to other persons prior to the Signing Date, or the creation and issuance, or an increase in the authorized or issued amount, whether pursuant to preemptive or similar rights or otherwise, of any other series of Preferred Stock, or any securities convertible into or exchangeable or exercisable for any other series of Preferred Stock, ranking equally with and/or junior to Designated Preferred Stock with respect to the payment of dividends (whether such dividends are cumulative or non-cumulative) and the distribution of assets upon liquidation, dissolution or winding up of the Corporation will not be deemed to adversely affect the rights, preferences, privileges or voting powers, and shall not require the affirmative vote or consent of, the holders of outstanding shares of the Designated Preferred Stock.

(d) Changes after Provision for Redemption. No vote or consent of the holders of Designated Preferred Stock shall be required pursuant to Section 7(c) above if, at or prior to the time when any such vote or consent would otherwise be required pursuant to such Section, all outstanding shares of the Designated Preferred Stock shall have been redeemed, or shall have been called for redemption upon proper notice and sufficient funds shall have been deposited in trust for such redemption, in each case pursuant to Section 5 above.

(e) Procedures for Voting and Consents. The rules and procedures for calling and conducting any meeting of the holders of Designated Preferred Stock (including, without limitation, the fixing of a record date in connection therewith), the solicitation and use of proxies at such a meeting, the obtaining of written consents and any other aspect or matter with regard to such a meeting or such consents shall be governed by any rules of the Board of Directors or any duly authorized committee of the Board of Directors, in its discretion, may adopt from time to time, which rules and procedures shall conform to the requirements of the Charter, the Bylaws, and applicable law and the rules of any national securities exchange or other trading facility on which

A-9

UST Sequence Number: 114

Designated Preferred Stock is listed or traded at the time.

Section 8. Record Holders. To the fullest extent permitted by applicable law, the Corporation and the transfer agent for Designated Preferred Stock may deem and treat the record holder of any share of Designated Preferred Stock as the true and lawful owner thereof for all purposes, and neither the Corporation nor such transfer agent shall be affected by any notice to the contrary.

Section 9. Notices. All notices or communications in respect of Designated Preferred Stock shall be sufficiently given if given in writing and delivered in person or by first class mail, postage prepaid, or if given in such other manner as may be permitted in this Certificate of Designations, in the Charter or Bylaws or by applicable law.

Section 10. No Preemptive Rights. No share of Designated Preferred Stock shall have any rights of preemption whatsoever as to any securities of the Corporation, or any warrants, rights or options issued or granted with respect thereto, regardless of how such securities, or such warrants, rights or options, may be designated, issued or granted.

Section 11. Replacement Certificates. The Corporation shall replace any mutilated certificate at the holder’s expense upon surrender of that certificate to the Corporation.
