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.

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 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

9

m07977-1957577.doc

Exhibit 3.1

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’ 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

10

m07977-1957577.doc

Exhibit 3.1

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.

(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.

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 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 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

12

m07977-1957577.doc

Exhibit 3.1

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.

(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

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

As used herein, the term “accrued” with respect to dividends includes both accrued and accumulated dividends. Dividends that are payable on Series B Preferred Stock on any Dividend Payment Date will be payable to holders of record of Series B 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”).

(ii) Subject to Section 4(a), the dividend rate, and the rate at which dividends shall accrue, on each share of Series B Preferred Stock, for each Dividend Period, shall be at an annual rate equal to 15%, calculated with respect to the Base Value of a share of Series B Preferred Stock.

(e) So long as any shares of Series B Preferred Stock remain outstanding, no dividends shall be declared or paid or set aside for payment on any Parity Securities for any period (other than with respect to a 382 Rights Plan) unless full dividends on all outstanding shares of Series B Preferred Stock for the then-current dividend period have been paid in full or declared and a sum sufficient for the payment thereof set aside for all outstanding shares of Series B Preferred Stock. To the extent the Corporation declares dividends on the Series B Preferred Stock and on any Parity Securities but does not make full payment of such declared dividends, the Corporation shall allocate the dividend payments on a pro rata basis among the holders of the shares of Series B Preferred Stock and the holders of any Parity Securities then outstanding. For purposes of calculating the pro rata allocation of partial dividend payments, the Corporation shall allocate those payments so that the respective amounts of those payments bear the same ratio to each other as all accrued and unpaid dividends per share on the Series B Preferred Stock and all Parity Securities bear to each other.

(f) At any time that dividends on the Series B Preferred Stock are not cumulative, and if a Conversion Date with respect to any share of Series B Preferred Stock is prior to the record date for the payment of any

5

m07977-1957577.doc

Exhibit 3.1

dividend on the Common Stock, the Holder of such share of Series B Preferred Stock will not have the right to receive any corresponding dividends on the Series B Preferred Stock. At any time that dividends on the Series B Preferred Stock are not cumulative, and if the Conversion Date with respect to any share of Series B Preferred Stock is after the Dividend Record Date for any declared dividend and prior to the payment date for that dividend, the Holder thereof shall receive that dividend on the relevant payment date if such Holder was the Holder of record on the Dividend Record Date for that dividend. Any accrued and unpaid cumulative dividends on the Series B Preferred Stock shall be payable in cash on the Conversion Date.

Section 5. Liquidation.

(a)In the event the Corporation voluntarily or involuntarily liquidates, dissolves or winds up, the Holders at the time shall be entitled to receive, for each share of the Series B Preferred Stock, the sum of (i) liquidating distributions in an amount equal to the Liquidation Preference, plus any accrued but unpaid dividends thereon to and including the date of such liquidation, out of assets legally available for distribution to the Corporation’s shareholders, before any distribution of assets is made to the holders of the Common Stock or any other Junior Securities and (ii) after all distributions have been made to Holders pursuant to clause (i) of this sentence, liquidating distributions, as determined by the Corporation (or the trustee or other Person or Persons administering its liquidation, dissolution or winding-up in accordance with applicable law) as of a date that is at least ten (10) Business Days before the first liquidating distribution is made on Series B Preferred Stock, that would be made on the number of shares of Common Stock equal to the Base Value divided by the Applicable Conversion Price as if all of the outstanding shares of Series B Preferred Stock had been converted into Common Stock on such date of determination, out of assets legally available for distribution to the Corporation’s shareholders, simultaneous with any distribution of assets made to the holders of the Common Stock. The Corporation shall notify each Holder of the amount it has calculated pursuant to this Section 5 by first-class mail, postage prepaid, addressed to the Holders at their respective last addresses appearing on the books of the Corporation. Such mailing shall be made not later than five Business Days before the first liquidating distribution is made on shares of Series B Preferred Stock.

(b) In the event the assets of the Corporation available for distribution to shareholders upon any liquidation, dissolution or winding-up of the affairs of the Corporation, whether voluntary or involuntary, shall be insufficient to pay in full the amounts payable with respect to all outstanding shares of the Series B Preferred Stock and the corresponding amounts payable on any Parity Securities, Holders and the holders of such Parity Securities shall share ratably in any distribution of assets of the Corporation in proportion to the full respective liquidating distributions to which they would otherwise be respectively entitled.

(c) For purposes of this Section 5, the Corporation’s consolidation or merger with or into any other entity, the consolidation or merger of any other entity with or into the Corporation, or the sale of all or substantially all of the Corporation’s property or business will not constitute a liquidation, dissolution or winding-up of the Corporation.

Section 6. Maturity. The Series B Preferred Stock shall be perpetual unless converted in accordance with this Articles of Amendment.

Section 7. Redemptions.

(a) Redemption. The shares of Series B Preferred Stock are not redeemable by the Corporation.

(b) No Sinking Fund. The Series B Preferred Stock will not be subject to any mandatory redemption, sinking fund or other similar provisions.

Section 8. Conversion.

(a) Effective as of the close of business on the Mandatory Conversion Date with respect to the shares of Series B Preferred Stock of a Holder, such Holder’s shares of Series B Preferred Stock shall automatically convert into shares of Common Stock as set forth below. The number of shares of Common Stock into which a share of Series B Preferred Stock shall be convertible shall be determined by dividing the Base Value by

6

m07977-1957577.doc

Exhibit 3.1

the Applicable Conversion Price (subject to the conversion procedures of Section 9 hereof), provided that cash will be paid in lieu of fractional shares in accordance with Section 13 hereof.

(b) Notwithstanding anything herein to the contrary, in no event shall a transferee of a Widely Disbursed Offering be entitled to receive shares of Common Stock upon any conversion of Series B Preferred Stock pursuant to this Section 8 or Section 11 to the extent (but only to the extent) that at such time the transferee Holder does not have any required Regulatory Approvals. If any delivery of shares of Common Stock owed to a transferee upon conversion of Series B Preferred Stock is not made, in whole or in part, as a result of the foregoing limitations, the Corporation’s obligation to make such delivery shall not be extinguished and the Corporation shall, at the option of the transferee Holder, deliver such shares as promptly as practicable after such converting Holder gives notice to the Corporation that the requirements of this Section 8(b) are met.

Section 9. Conversion Procedures.

(a) Each Holder shall promptly provide written notice to the Corporation of its intent to transfer its Series B Preferred Stock in a Widely Dispersed Offering and, promptly upon receipt of each required Regulatory Approval applicable to the transferee, such transferee shall provide written notice to the Corporation of such receipt. Upon occurrence of the Mandatory Conversion Date with respect to shares of any Holder, the Corporation shall provide notice of such conversion to such Holder (such notice a “Notice of Mandatory Conversion”). In addition to any information required by applicable law or regulation, the Notice of Mandatory Conversion with respect to such Holder shall state, as appropriate:

(i) the Mandatory Conversion Date applicable to such Holder;

(ii) the number of shares of Common Stock to be issued upon conversion of each share of Series B Preferred Stock held of record by such Holder and subject to such mandatory conversion; and

(iii) the place or places where certificates for shares of Series B Preferred Stock held of record by such Holder are to be surrendered for issuance of certificates representing shares of Common Stock.

(b) In the event that such Holder fails to surrender the required certificates for shares of Series B Preferred Stock held of record by such Holder within 30 days after delivery of the Mandatory Conversion Date, the Corporation shall, by written notice to such Holder, indicate which shares have been converted pursuant to Section 8.

(c) Effective immediately prior to the close of business on any Conversion Date with respect to any share of Series B Preferred Stock, dividends shall no longer be declared on any such converted share of Series B Preferred Stock and such share of Series B Preferred Stock shall cease to be outstanding, in each case, subject to the right of the Holder to receive any accrued and unpaid or declared and unpaid dividends on such share to the extent provided in Section 4(f) and any other payments to which such Holder is otherwise entitled pursuant to Section 8, Section 11 or Section 13 hereof, as applicable.

(d) No allowance or adjustment, except pursuant to Section 10, shall be made in respect of dividends payable to holders of the Common Stock of record as of any date prior to the close of business on any Conversion Date with respect to any share of Series B Preferred Stock. Prior to the close of business on the Conversion Date with respect to any share of Series B Preferred Stock, shares of Common Stock issuable upon conversion thereof, or other securities issuable upon conversion of, such share of Series B Preferred Stock shall not be deemed outstanding for any purpose, and the Holder thereof shall have no rights with respect to the Common Stock or other securities issuable upon conversion (including voting rights, rights to respond to tender offers for the Common Stock or other securities issuable upon conversion and rights to receive any dividends or other distributions on the Common Stock or other securities issuable upon conversion) by virtue of holding such share of Series B Preferred Stock.

(e) Shares of Series B Preferred Stock duly converted in accordance with Section 8 or Section 11 of this Articles of Amendment will resume the status of authorized and unissued preferred stock, undesignated as to series and available for future issuance. The Corporation may, from time to time, take such appropriate

7

m07977-1957577.doc

Exhibit 3.1

action as may be necessary to reduce the authorized number of shares of Series B Preferred Stock; provided, however, that the Corporation shall not take any such action if such action would reduce the authorized number of shares of Series B Preferred Stock below the sum of (i) the number of shares of Series B Preferred Stock then outstanding and (ii) the number of shares of Series B Preferred Stock issuable upon the exercise of any warrants then outstanding.

(f) The Person or Persons entitled to receive the Common Stock and/or cash, securities or other property issuable upon conversion of Series B Preferred Stock shall be treated for all purposes as the record holder(s) of such shares of Common Stock and/or securities as of the close of business on the applicable Conversion Date with respect thereto. In the event that a Holder shall not by written notice designate the name in which shares of Common Stock and/or cash, securities or other property (including payments of cash in lieu of fractional shares) to be issued or paid upon conversion of shares of Series B Preferred Stock should be registered or paid or the manner in which such shares should be delivered, the Corporation shall be entitled to register and deliver such shares, and make such payment, in the name of the Holder and in the manner shown on the records of the Corporation.

(g) On the Mandatory Conversion Date with respect to any share of Series B Preferred Stock, certificates representing shares of Common Stock shall be issued and delivered to the Holder thereof or such Holder’s designee upon presentation and surrender of the certificate evidencing the Series B Preferred Stock to the Corporation and, if required, the furnishing of appropriate endorsements and transfer documents and the payment of all transfer and similar taxes.

Section 10. Anti-Dilution Adjustments.

(a) The Conversion Price shall be subject to the following adjustments.

(i) Stock Dividends and Distributions. If the Corporation pays dividends or other distributions on the Common Stock in shares of Common Stock, then the Conversion Price in effect immediately prior to the Ex-Date for such dividend or distribution will be multiplied by the following fraction:

OS0

OS1

Where,

OS0 =	the number of shares of Common Stock outstanding immediately prior to the Ex-Date for such dividend or distribution.
OS1 =	the sum of the number of shares of Common Stock outstanding immediately prior to the Ex-Date for such dividend or distribution plus the total number of shares of Common Stock constituting such dividend or distribution.

For the purposes of this clause (i), the number of shares of Common Stock at the time outstanding shall not include shares acquired by the Corporation. If any dividend or distribution described in this clause (i) is declared but not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to make such dividend or distribution, to such Conversion Price that would be in effect if such dividend or distribution had not been declared.

(ii) Subdivisions, Splits and Combination of the Common Stock. If the Corporation subdivides, splits or combines the shares of Common Stock, then the Conversion Price in effect immediately prior to the effective date of such share subdivision, split or combination will be multiplied by the following fraction:

OS0

OS1

Where,

8

m07977-1957577.doc

Exhibit 3.1

OS0 =	the number of shares of Common Stock outstanding immediately prior to the effective date of such share subdivision, split or combination.
OS1 =	the number of shares of Common Stock outstanding immediately after the opening of business on the effective date of such share subdivision, split or combination.

For the purposes of this clause (ii), the number of shares of Common Stock at the time outstanding shall not include shares acquired by the Corporation. If any subdivision, split or combination described in this clause (ii) is announced but the outstanding shares of Common Stock are not subdivided, split or combined, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to subdivide, split or combine the outstanding shares of Common Stock, to such Conversion Price that would be in effect if such subdivision, split or combination had not been announced.

(iii) Issuance of Stock Purchase Rights. If the Corporation issues to all or substantially all holders of the shares of Common Stock rights or warrants (other than rights or warrants issued pursuant to a dividend reinvestment plan or share purchase plan or other similar plans) entitling them, for a period of up to 45 days from the date of issuance of such rights or warrants, to subscribe for or purchase the shares of Common Stock at less than the Current Market Price on the date fixed for the determination of shareholders entitled to receive such rights or warrants, then the Conversion Price in effect immediately prior to the Ex-Date for such distribution will be multiplied by the following fraction:

OS0 + Y

OS0 + X

Where,

OS0 =	the number of shares of Common Stock outstanding immediately prior to the Ex-Date for such distribution.
X =	the total number of shares of Common Stock issuable pursuant to such rights or warrants.
Y =	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the Current Market Price on the date fixed for the determination of shareholders entitled to receive such rights or warrants.

For the purposes of this clause (iii), the number of shares of Common Stock at the time outstanding shall not include shares acquired by the Corporation. In the event that such rights or warrants described in this clause (iii) are not so issued, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to issue such rights or warrants, to the Conversion Price that would then be in effect if such issuance had not been declared. To the extent that such rights or warrants are not exercised prior to their expiration or shares of Common Stock are otherwise not delivered pursuant to such rights or warrants upon the exercise of such rights or warrants, the Conversion Price shall be readjusted to such Conversion Price that would then be in effect had the adjustment made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock actually delivered. In determining the aggregate offering price payable for such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants and the value of such consideration (if other than cash, to be determined by the Board of Directors).

(iv) Debt or Asset Distributions. If the Corporation distributes to all or substantially all holders of shares of Common Stock evidences of indebtedness, shares of capital stock, securities, cash or other assets (excluding any dividend or distribution referred to in clause (i) above, any rights or warrants referred to in clause (iii) above, any dividend or distribution paid exclusively in cash, any consideration payable in connection with a tender or exchange offer made by the Corporation or any of its subsidiaries, and any dividend of shares of capital stock of any class or series, or similar equity interests, of or relating to a subsidiary or other business unit in the case of certain spin-off transactions as described below), then the

9

m07977-1957577.doc

Exhibit 3.1

Conversion Price in effect immediately prior to the Ex-Date for such distribution will be multiplied by the following fraction:

SP0 – FMV

SP0

Where,

SP0 =

the Current Market Price per share of Common Stock on the Trading Day immediately preceding the Ex-Date.

FMV =

the fair market value of the portion of the distribution applicable to one share of Common Stock on such date as determined by the Board of Directors, provided that, if “FMV” as set forth above is equal to or greater than “SP0” as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall receive on the date on which such distribution is made to holders of Common Stock, for each share of Preferred Stock, the amount of such distribution such Holder would have received had such holder owned a number of shares of Common Stock equal to the Base Value divided by the Applicable Conversion Price on the Ex-Date for such distribution.

In a “spin-off”, where the Corporation makes a distribution to all holders of shares of Common Stock consisting of capital stock of any class or series, or similar equity interests of, or relating to, a subsidiary or other business unit, the Conversion Price will be adjusted on the 15th Trading Day after the effective date of the distribution by multiplying such Conversion Price in effect immediately prior to such 15th Trading Day by the following fraction:

MP0

MP0 + MPS

Where,

MP0 =

the average of the Closing Prices of the Common Stock over the first ten Trading Days commencing on and including the fifth Trading Day following the effective date of such distribution.

MPS =

the average of the Closing Prices of the capital stock or equity interests representing the portion of the distribution applicable to one share of Common Stock over the first ten Trading Days commencing on and including the fifth Trading Day following the effective date of such distribution, or, if not traded on a national or regional securities exchange or over-the-counter market, the fair market value of the capital stock or equity interests representing the portion of the distribution applicable to one share of Common Stock on such date as determined by the Board of Directors.

In the event that such distribution described in this clause (iv) is not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay or make such dividend or distribution, to the Conversion Price that would then be in effect if such dividend or distribution had not been declared.

(v) Cash Distributions. If the Corporation makes a distribution consisting exclusively of cash to all holders of the Common Stock, excluding (a) any cash dividend on the Common Stock to the extent a corresponding cash dividend is paid on the Series B Preferred Stock pursuant to Section 4(b), (b) any cash that is distributed in a Reorganization Event or as part of a “spin-off” referred to in clause (iv) above, (c) any

10

m07977-1957577.doc

Exhibit 3.1

dividend or distribution in connection with the Corporation’s liquidation, dissolution or winding-up, and (d) any consideration payable in connection with a tender or exchange offer made by the Corporation or any of its subsidiaries, then in each event, the Conversion Price in effect immediately prior to the Ex-Date for such distribution will be multiplied by the following fraction:

SP0 – DIV

SP0

Where,

SP0 =	the Closing Price per share of Common Stock on the Trading Day immediately preceding the Ex-Date.
DIV =	the amount per share of Common Stock of the cash distribution, as determined pursuant to the introduction to this paragraph (v).

In the event that any distribution described in this clause (v) is not so made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay such distribution, to the Conversion Price which would then be in effect if such distribution had not been declared.

Notwithstanding the foregoing, if “DIV” as set forth above is equal to or greater than “SP0” as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive on the date on which the relevant cash dividend or distribution is distributed to holders of Common Stock, for each share of Preferred Stock, the amount of cash such Holder would have received had such Holder owned a number of shares of Common Stock equal to the Base Value divided by the Applicable Conversion Price on the Ex-Date for such distribution.

(vi) Self Tender Offers and Exchange Offers. If the Corporation or any of its subsidiaries successfully completes a tender or exchange offer for the Common Stock where the cash and the value of any other consideration included in the payment per share of the Common Stock exceeds the Closing Price per share of the Common Stock on the Trading Day immediately succeeding the expiration of the tender or exchange offer, then the Conversion Price in effect at the close of business on such immediately succeeding Trading Day will be multiplied by the following fraction:

OS0 x SP0

AC + (SP0 x OS1)

Where,

SP0 =	the Closing Price per share of Common Stock on the Trading Day immediately succeeding the expiration of the tender or exchange offer.
OS0 =	the number of shares of Common Stock outstanding immediately prior to the expiration of the tender or exchange offer, including any shares validly tendered and not withdrawn.
OS1 =	the number of shares of Common Stock outstanding immediately after the expiration of the tender or exchange offer.
AC =	the aggregate cash and fair market value of the other consideration payable in the tender or exchange offer, as determined by the Board of Directors.

In the event that the Corporation, or one of its subsidiaries, is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Corporation, or such subsidiary, is permanently prevented by applicable law from effecting any such purchases, or all such purchases are

11

m07977-1957577.doc

Exhibit 3.1

rescinded, then the Conversion Price shall be readjusted to be such Conversion Price that would then be in effect if such tender offer or exchange offer had not been made.

(vii) Rights Plans. To the extent that the Corporation has a rights plan in effect with respect to the Common Stock on the Mandatory Conversion Date, upon conversion of any shares of the Series B Preferred Stock, Holders will receive, in addition to the shares of Common Stock, the rights under the rights plan, unless, prior to the Mandatory Conversion Date, the rights have separated from the shares of Common Stock, in which case the Conversion Price will be adjusted at the time of separation as if the Corporation had made a distribution to all holders of the Common Stock as described in clause (iv) above, subject to readjustment in the event of the expiration, termination or redemption of such rights.

(b) The Corporation may make such decreases in the Conversion Price, in addition to any other decreases required by this Section 10, if the Board of Directors deems it advisable to avoid or diminish any income tax to holders of the Common Stock resulting from any dividend or distribution of shares of Common Stock (or issuance of rights or warrants to acquire shares of Common Stock) or from any event treated as such for income tax purposes or for any other reason.

(c) (i) All adjustments to the Conversion Price shall be calculated to the nearest 1/10 of a cent. No adjustment in the Conversion Price shall be required if such adjustment would be less than $0.01; provided that any adjustments which by reason of this subparagraph are not required to be made shall be carried forward and taken into account in any subsequent adjustment; provided further that on the Mandatory Conversion Date adjustments to the Conversion Price will be made with respect to any such adjustment carried forward and which has not been taken into account before such date.

(ii) No adjustment to the Conversion Price shall be made if Holders may participate in the transaction that would otherwise give rise to an adjustment, as a result of holding the Series B Preferred Stock (including without limitation pursuant to Section 4(b) hereof), without having to convert the Series B Preferred Stock, as if they held the full number of shares of Common Stock into which a share of the Series B Preferred Stock may then be converted. No single event shall be subject to adjustment under more than one subsection of this Section 10 so as to result in duplication.

(iii) The Applicable Conversion Price shall not be adjusted:

(A) with respect to a 382 Rights Plan; provided that Holders of Series B Preferred Stock participate in such distribution under such 382 Rights Plan as if their shares of Series B Preferred Stock were converted into shares of Common Stock pursuant to Section 8 hereof;

(B) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Corporation’s securities and the investment of additional optional amounts in shares of Common Stock under any such plan;

(C) upon the issuance of any shares of Common Stock or rights or warrants to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Corporation or any of its subsidiaries;

(D) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the date shares of the Series B Preferred Stock were first issued and not substantially amended thereafter;

(E) for a change in the par value or no par value of Common Stock; or

(F) for accrued and unpaid dividends on the Series B Preferred Stock.

(d) Whenever the Conversion Price is to be adjusted in accordance with Section 10(a) or Section 10(b), the Corporation shall: (i) compute the Conversion Price in accordance with Section 10(a) or Section 10(b), taking into account the one cent threshold set forth in Section 10(c) hereof; (ii) as soon as practicable following the occurrence of an event that requires an adjustment to the Conversion Price pursuant to Section

12

m07977-1957577.doc

Exhibit 3.1

10(a) or Section 10(b), taking into account the one percent threshold set forth in Section 10(c) hereof (or if the Corporation is not aware of such occurrence, as soon as practicable after becoming so aware), provide, or cause to be provided, a written notice to the Holders of the occurrence of such event; and (iii) as soon as practicable following the determination of the revised Conversion Price in accordance with Section 10(a) or Section 10(b) hereof, provide, or cause to be provided, a written notice to the Holders setting forth in reasonable detail the method by which the adjustment to the Conversion Price was determined and setting forth the revised Conversion Price.

Section 11. Reorganization Events.

(a) In the event that, prior to the Mandatory Conversion Date with respect to the shares of Series B Preferred Stock of any Holder, there occurs:

(i) any consolidation, merger or other similar business combination of the Corporation with or into another Person, in each case pursuant to which the Common Stock will be converted into cash, securities or other property of the Corporation or another Person;

(ii) any sale, transfer, lease or conveyance to another Person of all or substantially all of the property and assets of the Corporation, in each case pursuant to which the Common Stock will be converted into cash, securities or other property of the Corporation or another Person;

(iii) any reclassification of the Common Stock into securities including securities other than the Common Stock; or

(iv) any statutory exchange of the outstanding shares of Common Stock for securities of another Person (other than in connection with a merger or acquisition);

(any such event specified in this Section 11(a), a “Reorganization Event”) then, subject to Section 8(b), each share of such Holder’s Series B Preferred Stock outstanding immediately prior to such Reorganization Event shall remain outstanding but each Holder shall have the right, at its option, subject to the terms and provisions of this Section 11, to convert any or all of such Holder’s shares of Series B Preferred Stock, effective as of the close of business on the Reorganization Conversion Date (with the term “Regulatory Approval” applied for such purpose, as applicable, to the surviving entity in such Reorganization Event and its securities included in the Exchange Property (as defined below)), into the type and amount of securities, cash and other property receivable in such Reorganization Event by the Holder (other than a counterparty to the Reorganization Event or an Affiliate of such counterparty) in respect of each such share of Series B Preferred Stock equal to the number of shares of Common Stock into which one share of Series B Preferred Stock would then be convertible assuming that a Mandatory Conversion Date in respect of such shares of Series B Preferred Stock had occurred (such securities, cash and other property, the “Exchange Property”).

(b) The conversion right of a Holder of Series B Preferred Stock pursuant to this Section 11 shall be exercised by the Holder by the surrender of the certificates representing the shares to be converted to the Corporation or to the transfer agent for the Corporation, accompanied by a notice of reorganization conversion, no later than the tenth day following the date of delivery to each Holder of a notice from the Corporation of the expected consummation or the consummation of a Reorganization Event.

(i) Immediately prior to the close of business on the Reorganization Conversion Date, each converting Holder of Series B Preferred Stock shall be deemed to be the Holder of record of the number of shares of Common Stock deemed to be issuable upon conversion of such Holder’s Series B Preferred Stock in accordance with clause (i) or (ii) of Section 11(a), notwithstanding that the share register of the Corporation shall then be closed or that certificates representing such Common Stock shall not then be actually delivered to such Person.

13

m07977-1957577.doc

Exhibit 3.1

(ii) Upon notice from the Corporation, each Holder of Series B Preferred Stock so converted shall promptly surrender to the Corporation or its transfer agent certificates representing the shares so converted (if not previously delivered), duly endorsed in blank or accompanied by proper instruments of transfer.

(c) In the event that holders of the shares of Common Stock have the opportunity to elect the form of consideration to be received in connection with any Reorganization Event, the Holders shall be entitled to the same right of election as holders of the shares of Common Stock with respect to the form of consideration to be received pursuant to this Section 11.

(d) The above provisions of this Section 11 shall similarly apply to successive Reorganization Events and the provisions of Section 10 shall apply to any shares of capital stock of the Corporation (or any successor) received by the holders of the Common Stock in any such Reorganization Event.

(e) The Corporation (or any successor) shall, within seven days of the consummation of any Reorganization Event, provide written notice to the Holders of such consummation of such event and of the kind and amount of the cash, securities or other property that constitutes the Exchange Property. Failure to deliver such notice shall not affect the operation of this Section 11.

(f) The Corporation shall not enter into any agreement for a transaction constituting a Reorganization Event unless such agreement provides for or does not interfere with or prevent (as applicable) conversion of the Series B Preferred Stock into the Exchange Property in a manner that is consistent with and gives effect to this Section 11.

Section 12. Voting Rights.

(a) Holders will not have any voting rights, including the right to elect any directors, except (i) voting rights, if any, required by law, and (ii) voting rights, if any, described in this Section 12.

(b) So long as any shares of Series B Preferred Stock are outstanding, the vote or consent of the Holders of three-quarters of the shares of Series B Preferred Stock at the time outstanding voting as a single class with all other classes and series of Parity Securities having similar voting rights then outstanding, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, will be necessary for effecting or validating, whether or not such approval is required by Washington law:

(i) any amendment or alteration (including by means of a merger, consolidation or otherwise) of the Articles of Incorporation to authorize or create, or increase the authorized amount of, any shares of, or any securities convertible into shares of, any class or series of the Corporation’s capital stock ranking prior to the Series B Preferred Stock in the payment of dividends or in the distribution of assets on any liquidation, dissolution or winding-up of the Corporation;

(ii) any amendment, alteration or repeal (including by means of a merger, consolidation or otherwise) of any provision of the Articles of Incorporation (including this Articles of Amendment) or the Bylaws that would significantly and adversely alter or change the terms, rights, preferences or privileges of the Series B Preferred Stock; or

(iii) the consummation of a binding share exchange or reclassification involving the Series B Preferred Stock or a merger or consolidation of the Corporation with another entity;

provided, however, that a Holder will have no right to vote under this provision or under Washington law if such voting rights arise due to a Reorganization Event if (1) the Corporation shall have complied with Section 11(f) or (2) in each case (a) the Series B Preferred Stock remains outstanding or, in the case of any merger or consolidation with respect to which the Corporation is not the surviving or resulting entity, is converted into or exchanged for preference securities of the surviving or resulting entity or its ultimate parent, that is an entity organized and existing under the laws of the United States of America, any state thereof or the District of Columbia, and (b) such Series B Preferred Stock remaining outstanding or such preference securities, as the case may be, have such rights (including, but not limited to, the right of

14

m07977-1957577.doc

Exhibit 3.1

conversion), preferences, privileges and voting powers that, taken as a whole, as are not materially less favorable to the Holders thereof than the rights, preferences, privileges and voting powers of the Series B Preferred Stock, taken as a whole, immediately prior to the Reorganization Event; provided further,that any increase in the amount of the authorized Preferred Stock or any securities convertible into Preferred Stock or the creation and issuance, or an increase in the authorized or issued amount, of any series of Preferred Stock or any securities convertible into preferred stock ranking equally with and/or junior to the Series B Preferred Stock with respect to the payment of dividends (whether such dividends are cumulative or non-cumulative) and/or the distribution of assets upon the Corporation’s liquidation, dissolution or winding-up will not, in and of itself, be deemed to affect the voting powers, preferences or special rights of the Series B Preferred Stock and, notwithstanding any provision of Washington law, Holders will have no right to vote solely by reason of such an increase, creation or issuance.

Each holder of Series B Preferred Stock will have one vote per share on any matter on which holders of Series B Preferred Stock are entitled to vote, including any action by written consent.

If an amendment, alteration, repeal, share exchange, reclassification, merger or consolidation described above would adversely affect one or more but not all series of Preferred Stock with like voting rights (including the Series B Preferred Stock for this purpose), then only the series affected and entitled to vote shall vote as a class in lieu of all such series of Preferred Stock.

(c) Notwithstanding the foregoing, Holders shall not have any voting rights if, at or prior to the effective time of the act with respect to which such vote would otherwise be required, all outstanding shares of Series B Preferred Stock shall have been converted into shares of Common Stock.

Section 13. Fractional Shares.

(a) No fractional shares of Common Stock will be issued as a result of any conversion of shares of Series B Preferred Stock.
