Such right shall be a contract right and shall include the right to be paid by the Corporation expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, that the payment of such expenses incurred by a director, officer or professional or supervisory employee in his or her capacity as a director, officer or professional or supervisory employee (and not in any other capacity in which service was or is rendered by such person while a director, officer or professional or supervisory employee including, without limitation, service to an employee benefit plan) in advance of the final disposition of such proceeding, shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director, officer or professional or supervisory employee, to repay all amounts so advanced if it should be determined ultimately that such director, officer or professional or supervisory employee is not entitled to be indemnified under this Article XIII or otherwise. A-13 B. If a claim under Section A is not paid in full by the Corporation within thirty days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expenses of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the Iowa Business Corporation Act for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel, or its shareholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the Iowa Business Corporation Act, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel, or its shareholders) that the claimant had not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant had not met the applicable standard of conduct. C. Indemnification provided hereunder shall, in the case of the death of the person entitled to indemnification, inure to the benefit of such person's heirs, executors or other lawful representatives. The invalidity or unenforceability of any provision of this Article XIII shall not affect the validity or enforceability of any other provision of this Article XIII. D. Any action taken or omitted to be taken by (i) any director, officer or professional or supervisory employee in good faith and in compliance with or pursuant to any order, determination, approval or permission made or given by a commission, board, official or other agency of the United States or of any state or other governmental authority with respect to the property or affairs of the Corporation or any such business corporation, not-for-profit corporation, joint venture, trade association or other entity over which such commission, board, official or agency has jurisdiction or authority or purports to have jurisdiction or authority or (ii) by any director of the Corporation pursuant to Section D of Article IX shall be presumed to be in compliance with the standard of conduct set forth in Section 490.851 (or any successor provision) of the Iowa Business Corporation Act whether or not, in the case of clause (i), it may thereafter be determined that such order, determination, approval or permission was unauthorized, erroneous, unlawful or otherwise improper. A-14 E. Unless finally determined, the termination of any litigation, whether by judgment, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that the action taken or omitted to be taken by the person seeking indemnification did not comply with the standard of conduct set forth in Section 490.851 (or any successor provision) of the Iowa Business Corporation Act. F. The rights conferred on any person by this Article XIII shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the Articles of Incorporation, Bylaws, agreement, vote of shareholders or disinterested directors or otherwise. Indemnification provided hereunder shall, in the case of the death of the person entitled to indemnification, inure to the benefit of such person's heirs, executors or other lawful representatives. The invalidity or unenforceability of any provision of this Article XIII shall not affect the validity or enforceability of any other provision of this Article XIII. G. The Corporation may maintain insurance, at its expense, to protect itself and any such director, officer, professional or supervisory employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any such expense, liability or loss under the Iowa Business Corporation Act.

No Dividend shall be declared on the shares of any series of Class I Preferred Stock in respect of the accumulations for any quarterly Dividend period or portion thereof unless Dividends shall likewise be or have been declared with respect to accumulations on all then outstanding shares of Class I Preferred Stock of each other series thereof and on all outstanding shares of Parity Stock of each series thereof for the same period or portion thereof. Except as provided in Section (C)(2) of Division II, the ratios of the Dividends declared to Dividends accumulated with respect to any quarterly Dividend period on the shares of Class I Preferred Stock of each series thereof and on all shares of Parity Stock of each series thereof outstanding shall be identical. Accumulations of Dividends shall not bear interest. So long as any shares of Class I Preferred Stock are outstanding, no Dividend shall be paid or declared, or other distribution made, on Junior Shares, nor shall any Junior Shares be purchased, redeemed, retired or otherwise acquired for a consideration if Preferential Dividends on outstanding shares of Class I Preferred Stock for the current and all past quarterly Dividend periods or portions thereof shall not have been paid, or declared and set apart for payment, or if the Corporation shall be in default or deficient under any requirement of a sinking fund established with respect to outstanding shares of Class I Preferred Stock of any series for any period then elapsed; provided, however, that the restrictions of this paragraph shall not apply to the declaration and payment of Dividends on Junior Shares if payable solely in Junior Shares, nor to the acquisition of any Junior Shares through the application of the proceeds of any Junior Shares sold at or about the time of such acquisition, nor shall such restrictions prevent the transfer of any amount from surplus to stated capital. (C) Liquidation Preferences. In the event of involuntary dissolution, liquidation or winding up ("Liquidation") of the Corporation, the holders of shares of Class I Preferred Stock of each series outstanding shall be entitled to receive out of the assets of the Corporation an amount per share equivalent to the par value thereof, plus an amount equivalent to Preferential Dividends at the rate fixed and A-18 determined for such series accrued and unpaid to the date fixed for payment, but no more. In the event of voluntary Liquidation of the Corporation, the holders of shares of Class I Preferred Stock of each series outstanding shall be entitled to receive out of the assets of the Corporation such amount per share as shall have been fixed and determined for such series by the Board of Directors, plus an amount equivalent to Preferential Dividends at the rate fixed and determined for such series accrued and unpaid to the date fixed for payment, but no more. Until payment to the holders of outstanding shares of Class I Preferred Stock as aforesaid, or until moneys or other assets sufficient for such payment shall have been set apart for payment by the Corporation, separate and apart from its other funds and assets for the account of such holders so as to be and continue to be available for payment to such holders, no payment or distribution shall be made to holders of Junior Shares in connection with or upon such Liquidation. Neither a consolidation nor merger of the Corporation with or into any other corporation, nor a merger of any other corporation into the Corporation, nor the purchase or redemption of all or any part of the outstanding shares of any class or classes of the Corporation, nor the sale or transfer of the property and business of the Corporation as or substantially as an entirety, shall be construed to be a Liquidation of the Corporation within the meaning of this Division I. (D) Redemptions. The Corporation may at its option expressed by vote of the Board of Directors, at any time or from time to time, redeem the whole or any part of the shares of Class I Preferred Stock, or of any series thereof, at the redemption price or prices at the time in effect, any such redemption of shares of Class I Preferred Stock to be at such time and at such place in the City of Chicago, State of Illinois, as shall likewise be determined by vote of the Board of Directors. Notice of any proposed redemption of shares of Class I Preferred Stock shall be given by the Corporation by mailing a copy of such notice, not more than 40 nor less than 30 days prior to the time fixed for redemption, to the holders of record of the shares of Class I Preferred Stock to be redeemed, at their respective addresses then appearing on the books of the Corporation. It shall not be necessary that the holders of record of any shares of Class I Preferred Stock to be redeemed shall actually have received notice of redemption thereof, provided the same shall have been mailed as aforesaid. In case less than all of the shares of Class I Preferred Stock of any series are to be A-19 redeemed, the shares so to be redeemed shall be determined by lot in such manner as may be prescribed by the Board of Directors, and the certificates evidencing such shares shall be specified by number in the notice of such redemption. By the time so fixed for redemption, the Corporation shall, and at any time within 40 days prior to such time may, deposit in trust, for the account of the holders of the shares of Class I Preferred Stock to be redeemed, funds necessary for such redemption with a bank or trust company in good standing, organized under the laws of the United States of America or of the State of Illinois, located in the City of Chicago, Illinois, and having a combined capital, surplus and undivided profits of at least $5,000,000, which shall be designated in such notice of redemption. Notice of redemption having been mailed and funds necessary for such redemption having been deposited as aforesaid so that such funds shall be forthwith available to holders of shares of Class I Preferred Stock to be redeemed upon surrender of certificates evidencing such shares, then, notwithstanding that the time fixed for such redemption as aforesaid may not yet have occurred or the certificates evidencing shares to be redeemed may not have been surrendered for cancellation, nevertheless all shares to be redeemed shall be deemed no longer to be outstanding for any purpose, and all voting and other rights with respect to such shares shall thereupon cease and terminate, excepting only the right of the holders of the certificates for such shares to receive, out of funds so deposited in trust, the redemption funds, without interest, to which they are entitled, and the right to exercise any privilege of conversion not theretofore expiring, the Corporation to be entitled to the return of any funds deposited for redemption of shares converted pursuant to such privilege. Any interest accrued on funds so deposited shall be paid to the Corporation from time to time. In case the holder of shares of Class I Preferred Stock which shall have been called for redemption shall not, within six years after the redemption date, claim the amount deposited with respect to the redemption of such shares, the bank or trust company in which such deposit was made shall upon demand pay over to the Corporation such unclaimed amount and thereupon such bank or trust company shall be relieved of all responsibility in respect thereof to such holder. (E) Repurchases; Limitations on Reacquisitions. Subject to applicable law and the provisions of this Division I, the Corporation may from time to time purchase or otherwise acquire outstanding shares of Class I Preferred Stock at a price per share not exceeding the amount at the time payable in the event of redemption thereof otherwise than through the operation of the applicable sinking fund, if any. A-20 No shares of Class I Preferred Stock shall be purchased, redeemed, retired or otherwise acquired for a valuable consideration if all accumulations of Dividends on the shares of Class I Preferred Stock of all series thereof, and on the shares of Parity Stock of all series thereof, for all past quarterly Dividend periods or portions thereof shall not have been paid, or declared and a sum sufficient for the payment thereof set apart, or if the Corporation shall be in default or deficient under any requirement of a sinking fund established with respect to outstanding shares of Class I Preferred Stock of any series thereof and with respect to outstanding shares of Parity Stock of any series thereof, for any period then elapsed.

In determining such gross income, the Board of Directors shall make such adjustment, by way of increase or decrease in such gross income, as shall, in its opinion, be necessary to give effect, for the entire 12 months for which such gross income is determined, to any acquisition or disposition of property the income from which can be separately ascertained.

(3) Notice of any proposed redemption of any Merger Series shares of Class M Preferred Stock shall be given by the Corporation by mailing a copy of such notice not more than sixty (60) nor less than thirty (30) days prior to the date fixed for such redemption to the holders of record of such shares to be redeemed, at their respective addresses then appearing on the books of the Corporation; but no failure to mail such notice or any defect therein, or in the mailing thereof, shall affect the validity of the proceedings for the redemption of any Merger Series shares of Class M Preferred Stock so to be redeemed. (4) In case of redemption of only a part of the shares of any Merger Series of Class M Preferred Stock at the time outstanding, the shares of such Merger Series of Class M Preferred Stock to be redeemed shall be selected by lot in such manner as the Board of Directors may determine.

(6) Notice having been given and funds necessary for such redemption having been deposited, all as provided in this Section (D), all Merger Series shares of Class M Preferred Stock with respect to the redemption of which such notice shall be given and deposit made, shall thenceforth, whether or not the date fixed for such redemption shall have yet occurred, or the certificates for such shares shall have been surrendered for cancellation, be deemed no longer to be outstanding for any purpose, and all rights with respect to such shares shall thereupon cease and terminate except only the right of the holders of the certificates for such shares to receive, out of the funds so deposited in A-35 trust, upon or after the redemption date (unless an earlier date is fixed by the Board of Directors of the Corporation), the redemption funds, without interest, to which they are entitled upon endorsement, if required, and surrender of their certificates for such shares. (7) At the expiration of six (6) years after the redemption date such trust shall terminate and any such moneys then remaining on deposit with such bank or trust company which are unclaimed by the holders of the certificates for the Merger Series shares of Class M Preferred Stock which have been so redeemed, plus interest thereon, if any, shall be paid by such bank or trust company to the Corporation, free of trust, and thereafter the holders of the certificates for such shares shall have no claim against such bank or trust company but only claims as unsecured creditors against the Corporation for the amount payable upon the redemption thereof, without interest. (8) Any interest on or other accretions to funds deposited with such bank or trust company pursuant to this Section (D) shall belong to the Corporation. (E) Repurchase. (1) The Corporation may from time to time purchase or otherwise acquire Merger Series shares of Class M Preferred Stock at a price not exceeding the amount at the time payable in the event of redemption thereof otherwise than through the operation of the applicable sinking fund, if any. (2) If and so long as the Corporation shall be in default in the payment of any quarterly Dividend on any shares of Class I Preferred Stock or Merger Series shares of Class M Preferred Stock, or shall be in default in the payment of funds into or the setting aside of funds for any sinking fund created for any shares of Class I Preferred Stock or Merger Series shares of Class M Preferred Stock, the Corporation shall not (other than by the use of unapplied funds, if any, paid into or set aside for a sinking fund or funds prior to such default): (a) redeem any shares of Class I Preferred Stock or any Merger Series shares of Class M Preferred Stock, unless all shares of Class I Preferred Stock and all Merger Series shares of Class M Preferred Stock are redeemed, or A-36 (b) purchase or otherwise acquire for a valuable consideration any shares of Class I Preferred Stock or Merger Series shares of Class M Preferred Stock, except pursuant to offers of sale made by the holders of shares of Class I Preferred Stock and Merger Series shares of Class M Preferred Stock in response to an invitation for tenders given by mail by the Corporation simultaneously to the holders of record of all shares of Class I Preferred Stock and all Merger Series shares of Class M Preferred Stock then outstanding, at their respective addresses then appearing on the books of the Corporation. (F) Preference on Liquidation. (1) Before any distribution of any assets of the Corporation shall be made to the holders of any Common Stock or any other junior shares of the Corporation which rank below the Class I Preferred Stock and Class M Preferred Stock with respect to any assets, Dividends or other distributions: (a) in the event of any liquidation, dissolution or winding up ("Liquidation") of the Corporation which is voluntary: (i) the holders of the shares of the $1.7375 Series, $3.30 Series, $3.75 Series, $4.35 Series, $4.40 Series and $4.80 Series shall be entitled to receive an amount per share equal to the amount which would then be payable upon such share in the event of redemption thereof in accordance with Section (D) of this Division II, and no more; and (ii) the holders of the shares of the $3.90 Series and $4.20 Series shall be entitled to receive the amount of one hundred dollars ($100) per share plus accrued and unpaid Dividends to the date of payment of such amount, and no more.

(2) If upon any Liquidation the assets distributable among the holders of the shares of Class I Preferred Stock and Class M Preferred Stock shall be insufficient to permit the payment of the full preferential amounts to which they shall be entitled, then the entire assets of the Corporation to be distributed shall be distributed among the holders of the shares of Class I Preferred Stock and Class M Preferred Stock then outstanding ratably in proportion to the amounts to which such holders are respectively entitled. (3) If upon any Liquidation the holders of the shares of Class I Preferred Stock and Class M Preferred Stock shall receive the full preferential amounts to which they shall be entitled, the remaining assets and funds of the Corporation shall be distributed among the holders of the shares of Common Stock and of any other junior shares of the Corporation which rank below the Class I Preferred Stock and Class M Preferred Stock with respect to any assets, or Dividends or other distributions, according to their respective rights and preferences and according to their respective shares. (4) Neither a consolidation nor a merger of the Corporation, nor a sale or transfer of substantially all its assets as an entirety, nor a redemption or a purchase or other acquisition by the Corporation of less than all of its shares of any class at the time outstanding, shall be regarded as a Liquidation within the meaning of this Section (F). (G) Voting Rights. (1) Except to the extent required by law or as permitted by this Section (G), the holders of Merger Series shares of Class M Preferred Stock shall have no voting rights. (2) If at any time Dividends on any Class I Preferred Stock or Class M Preferred Stock shall be accrued and unpaid in an amount equivalent to six or more full quarterly Dividends, the holders of all shares of Class I Preferred Stock and Class M Preferred Stock, voting together as a single class for such purpose, shall be entitled until, but only until, all Dividends accrued and unpaid on all shares of Class I Preferred Stock and Class M Preferred Stock shall have been paid (or deposited in trust for payment on or before the next succeeding Dividend Payment Date with respect to shares of Class I Preferred Stock and Merger Series shares of A-38 Class M Preferred Stock, and on or before the next succeeding date or dates upon which Dividends are payable on other series of Class M Preferred Stock), to elect two (2) Directors of the Corporation. (3) While the holders of the shares of Class I Preferred Stock and Class M Preferred Stock remain entitled to elect two Directors of the Corporation, the payment of Dividends on Class I Preferred Stock and Class M Preferred Stock, including accrued and unpaid Dividends, shall not be unreasonably withheld if the financial condition of the Corporation permits payment thereof. (4) The right of the holders of the shares of Class I Preferred Stock and Class M Preferred Stock under this Section (G) to elect two Directors of the Corporation may be exercised at any annual meeting of shareholders or, within the limitations of this Section (G), at a special meeting of shareholders held for such purpose; whenever such right shall have become vested, upon request signed by any holder of record of shares of Class I Preferred Stock or Class M Preferred Stock and delivered to the Corporation at its principal office not less than ninety (90) days prior to the date for the annual meeting next following the date of such vesting, the President of the Corporation shall call a special meeting of shareholders, to be held within sixty (60) days after the receipt of such request, for the purpose of electing a new Board of Directors, of which two shall, subject to the provisions of this Section (G), be elected by a vote of the holders of the Class I Preferred Stock and Class M Preferred Stock, voting together as a single class, to serve until the next annual meeting or until their successors shall be elected and shall qualify. (5) No such special meeting shall be required to be held within 120 days after such a prior special meeting, and the term of office of each Director of the Corporation shall terminate at the time of any such special meeting or adjournment thereof, notwithstanding that the term for which such Director had been elected shall not then have expired, and provided that the successor of such Director is duly elected and qualified. (6) In the event that at any special meeting at which the holders of the shares of Class I Preferred Stock and Class M Preferred Stock shall be entitled to elect two Directors of the Corporation, a quorum of the holders of the shares of Class I Preferred Stock and Class M Preferred Stock shall not be present in person or by proxy, the holders of Common Stock, if a quorum thereof A-39 be present in person or by proxy, shall temporarily elect the Directors of the Corporation, which holders of the shares of Class I Preferred Stock and Class M Preferred Stock were entitled but failed to elect, such Directors to be designated as having been so elected and their term of office to expire at such time thereafter as their successors shall be elected by holders of the shares of Class I Preferred Stock and Class M Preferred Stock as provided in this Section (G). (7) Whenever the holders of the shares of Class I Preferred Stock and Class M Preferred Stock shall be entitled to elect two Directors, any holder of record of a share of Class I Preferred Stock or Class M Preferred Stock shall have the right, during regular business hours, in person or by a duly authorized representative, to examine the Corporation stock records of the Class I Preferred Stock and Class M Preferred Stock for the purpose of communicating with other holders of Class I Preferred Stock and Class M Preferred Stock with respect to the exercise of such right of election, and to make a list of such holders.

(9) The term of office of each Director of the Corporation shall terminate at the time of any such special meeting or adjournment thereof at which a quorum of holders of Common Stock shall be present in person or by proxy, notwithstanding that the term for which such Director had been elected shall not then have expired, and provided that the successor to such Director is duly elected and qualified. (10) If, during any interval between annual meetings of shareholders for the election of Directors and while the holders of the shares of Class I Preferred Stock and Class M Preferred Stock shall be entitled to elect A-40 two Directors, a Director in office who has been elected by the holders of the shares of Class I Preferred Stock and Class M Preferred Stock, shall, by reason of resignation, death or removal, cease to be a Director, (a) the vacancy or vacancies shall be filled by vote of the remaining Director then in office who was elected by the holders of the shares of Class I Preferred Stock and Class M Preferred Stock or who succeeded to a Director so elected, and (b) if any vacancy which occurred more than six months prior to the date of the next ensuing annual meeting is not so filled within forty (40) days after the occurrence thereof, the President of the Corporation shall call a special meeting of the holders of the shares of Class I Preferred Stock and Class M Preferred Stock and such vacancy shall be filled at such special meeting. (11) A Director elected by holders of the shares of Class I Preferred Stock and Class M Preferred Stock may be removed from office only by vote of the holders of a majority of the votes of the outstanding shares of Class I Preferred Stock and Class M Preferred Stock.

(13) At any meeting of shareholders at which the holders of the shares of Class I Preferred Stock and Class M Preferred Stock are required to vote by law or are permitted to vote by any articles of amendment to the Articles of Incorporation, each holder of Merger Series shares of Class M Preferred Stock shall have one vote for each such Merger Series share except the holders of $1.7375 Series Shares of Class M Preferred Stock which shall have 1/4 vote for each such $1.7375 Series Share, and each holder of shares of each other series of Class M Preferred Stock shall have the number or fraction of votes set forth for each such share in the articles of amendment to the Articles of Incorporation in which the terms of such series are determined, in each case standing in the name of such holder on the books of the Corporation on the record date fixed for such purpose, or, if no record date is fixed, on the date on which such vote is taken. A-41 (14) The holders of shares of Class M Preferred Stock shall not be entitled to receive notice of any meeting at which they are not entitled to vote. (15) No Preemptive Rights. No holder of Merger Series shares of Class M Preferred Stock as such shall have any preemptive or preferential right to purchase or subscribe for any shares of stock or rights or options to purchase stock or any other securities of the Corporation of any kind whatsoever whether now or hereafter authorized. A-42 DIVISION III Provisions Relating to Preference Stock (A) Issue in Series. The shares of Preference Stock may be divided into and issued in series, each of which shall be so designated as to distinguish the shares thereof from the shares of all other series and classes. Authority is hereby expressly vested in the Board of Directors to divide any or all of the shares of Preference Stock from time to time authorized into series, to fix the designation of each such series and, subject to the limitations stated herein or imposed by law, to fix and determine the following as to each such series: (1) the distribution ("Dividend") rate or rates for the shares of such series, or the facts ascertainable outside the Articles of Incorporation of the Corporation providing the basis for determining such Dividend rate or rates, which may vary according to a formula based upon market rates or rating agency ratings for such series or other designated securities and/or be determined periodically by auctions, remarketing or other methods, but only if the manner in which such facts are to operate upon such Dividend rate or rates shall be clearly and expressly set forth in Articles of Amendment to the Articles of Incorporation adopted by the Board of Directors of the Corporation for such purpose; the date or dates on which such Dividends may be payable; and the date from which Dividends on shares of such series shall be cumulative; (2) the price or prices at which, and the terms and conditions on which, such shares may be redeemed; (3) the amount payable upon each of such shares in the event of the voluntary or involuntary liquidation, dissolution or winding up ("Liquidation") of the Corporation; (4) sinking fund provisions, if any, for the redemption or purchase of such shares; and (5) the terms and conditions on which such shares may be converted into Common Stock, if such shares are to be issued with such privilege of conversion. (B) Dividends. Subject to the preferential rights of the holders of Class I Preferred Stock and Class M Preferred Stock with respect to the payment of Dividends, as set forth A-43 in Section (B) of Division I and in Section (C) of Division II, the holders of shares of Preference Stock of each series shall be entitled to receive, when and as declared by the Board of Directors from assets legally available for the payment thereof, Dividends at the rate fixed for such series, and no more, payable quarterly on the first day of each of the months of February, May, August and November in each year (the "quarterly Dividend Payment Dates"), each such quarterly Dividend payment to be in respect of the quarterly Dividend period ending with the day next preceding the date of such payment, except in the case of the first Dividend payable on shares of any series issued between quarterly Dividend Payment Dates, in which case such Dividend shall be for the period beginning with the date of issue of such shares or the next preceding quarterly Dividend Payment Date for the Preference Stock, as determined by the Board of Directors, and ending with the day next preceding either the first or the second quarterly Dividend Payment Date for the Preference Stock succeeding the date of issue of such shares, as determined by the Board of Directors. Notwithstanding the immediately preceding sentence, if so provided in the articles of amendment to the Articles of Incorporation establishing a particular series of Preference Stock, as authorized by Section (A) of this Division III, Dividends on the shares of such series may be declared payable on such dates and with respect to such periods as shall be set forth in such articles of amendment. Except as may be otherwise provided in the articles of amendment to the Articles of Incorporation establishing a particular series of Preference Stock, such Dividends shall accrue and be cumulative with respect to each share of each series from and including the beginning date of the period for which the first Dividend thereon was payable. No Dividend shall be declared in full on the outstanding shares of Preference Stock of any series ("Declaring Series") in respect of any Dividend period for the Declaring Series at the Dividend rate applicable to such Dividend period unless prior thereto or concurrently therewith Dividends in full shall likewise have been declared on all then outstanding Preference Stock of each other series ("Other Series") in respect of each Dividend period for each of the Other Series ending concurrently with, or prior to, the last day of the Dividend period first above specified, at the respective Dividend rates applicable from time to time to each Other Series. Whenever less than full Dividends shall be declared on the Declaring Series in respect of any Dividend period for the Declaring Series at the Dividend rate applicable to such Dividend period, Dividends on the outstanding shares of Preference Stock of all series shall be declared ratably in accordance with the respective amounts which would be payable on all such A-44 outstanding shares of Preference Stock if all Dividends, including accumulated Dividends, if any, were declared in full on the declaration date. Accumulations of Dividends shall not bear interest. So long as any shares of Preference Stock are outstanding, no Dividend shall be paid or declared, or other distribution made, on Junior Shares, nor shall any Junior Shares be purchased, redeemed, retired or otherwise acquired for a consideration, unless Dividends on the outstanding Preference Stock for the current and all past Dividend periods shall have been paid in full, or declared and set apart for payment, or if the Corporation shall be in default or deficient under any requirement or a sinking fund established with respect to outstanding shares of Preference Stock of any series for any period then elapsed; provided, however, that the restrictions of this Section (B) shall not apply to the declaration and payment of Dividends on Junior Shares if payable solely in Junior Shares, nor to the acquisition of any Junior Shares through the application of the proceeds of any Junior Shares sold at or about the time of such acquisition, nor shall such restrictions prevent the transfer of any amount from surplus to stated capital. (C) Liquidation Preferences. In the event of Liquidation of the Corporation, whether voluntary or involuntary, the holders of Preference Stock of each series outstanding shall be entitled to receive out of the assets of the Corporation, before any payment or distribution shall be made to the holders of any Junior Shares, such amount per share as shall have been fixed by the Board of Directors as the voluntary liquidation price or the involuntary liquidation price, as the case may be, for the shares of such series; provided, however, that no such payment to the holders of Preference Stock shall be made until payment in full shall have been made to the holders of all shares of Class I Preferred Stock and Class M Preferred Stock, or moneys or other assets sufficient for such payment shall have been set apart for payment by the Corporation, separate and apart from its other funds and assets for the account of such holders, in accordance with the provisions of Section (C) of Division I and Section (F) of Division II. If upon any such Liquidation the assets of the Corporation available for payment to shareholders are not sufficient to make payment in full to the holders of Preference Stock as above provided, payment shall be made to such holders ratably in accordance with the number of shares held by them respectively, and in case there shall then be outstanding more than one series of Preference Stock, ratably in accordance with the respective distributive amounts to which such holders shall be entitled. A-45 Neither a consolidation nor merger of the Corporation with or into any other corporation, nor a merger of any other corporation into the Corporation, nor the purchase or redemption of all or any part of the outstanding shares of any class or classes of the Corporation, nor the sale or transfer of the property and business of the Corporation as or substantially as an entirety, shall be construed to be a Liquidation of the Corporation within the meaning of the foregoing provisions. (D) Redemption and Repurchases. Subject to the limitations stated in Section (B) of Division I, Section (E) of Division II and in this Section (D), and except as may be otherwise provided in the articles of amendment to the Articles of Incorporation establishing a particular series, shares of Preference Stock of any one or more series may be called for redemption and redeemed, at the option of the Corporation, in whole at any time or in part from time to time, by the payment therefor in cash of the then applicable optional redemption price or prices fixed by the Board of Directors for the shares of such series, each redemption to be effected upon notice the same as that provided in Section (D) of Division I in respect of the redemption of Class I Preferred Stock. All other provisions of said Section (D) with respect to the method and effect of redemption of Class I Preferred Stock shall be applicable to the redemption of Preference Stock in the same manner and with the same force and effect as though such provisions were set forth in full in this Section (D). Subject to applicable law, to the provisions of Section (B) of Division I, Section (E) of Division II and to the provisions of this Division III, the Corporation may from time to time purchase or otherwise acquire outstanding shares of Preference Stock at a price per share not exceeding the amount at the time payable in the event of redemption thereof otherwise than through the operations of the applicable sinking fund, if any. If and so long as the Corporation shall be in default in the payment of any quarterly Dividend on shares of Preference Stock of any series, or shall be in default in the payment of funds into or the setting aside of funds for any sinking fund created for any series of the Preference Stock, the Corporation shall not (other than by the use of unapplied funds, if any, paid into or set aside for a sinking fund or funds prior to such default): (1) redeem any shares of Preference Stock unless all shares thereof are redeemed, or (2) purchase or otherwise acquire for a valuable consideration any shares of Preference Stock, except A-46 pursuant to offers of sale made by the holders of Preference Stock in response to an invitation for tenders given by mail by the Corporation simultaneously to the holders of record of all shares of Preference Stock then outstanding, at their respective addresses then appearing on the books of the Corporation. (E) Restrictions on Certain Corporation Action. So long as any shares of Preference Stock shall be outstanding, the Corporation shall not, without the affirmative vote or the written consent of the holders of at least two-thirds of the shares of Preference Stock at the time outstanding, or as of a record date fixed by the Board of Directors, create or authorize any shares of any class, other than the Class I Preferred Stock and Class M Preferred Stock (whether now or hereafter authorized), ranking prior to or on a parity with the Preference Stock with respect to the payment of Dividends or the distribution of assets upon the Liquidation of the Corporation. (F) Preemptive Rights. No holder of Preference Stock shall have any preemptive right to subscribe for or acquire additional shares of the Corporation of the same or any other class, whether such shares are now or hereafter authorized. (G) Cancellation. All shares of Preference Stock which shall be redeemed or repurchased pursuant to any sinking fund created for any series of Preference Stock, or applied in lieu of the payment of funds into or the setting aside of funds for any such sinking fund, and all shares of Preference Stock issued with the privilege of conversion into shares of Common Stock which shall be so converted, shall be retired and cancelled and shall not be reissued. Shares of Preference Stock otherwise redeemed, purchased or acquired by the Corporation may be reissued in the same manner as authorized but unissued shares of Preference Stock undesignated as to series until and unless cancelled by the Board of Directors pursuant to applicable law. (H) Definitions. In this Division III and in any articles of amendment to the Articles of Incorporation establishing a series of Preference Stock and fixing the designation and terms thereof, the meanings below assigned shall control: "Junior Shares" shall mean shares of any class ranking subordinate to the Preference Stock both as to Dividends and upon the Liquidation of the Corporation, including Common Stock. A-47 (I) Voting Rights. (1) Except to the extent required by law or as permitted by this Division III, the holders of shares of Preference Stock shall have no voting rights. (2) If at any time Dividends on any shares of Preference Stock shall be accrued and unpaid in an amount equivalent to six or more full quarterly Dividends, the holders of all shares of Preference Stock shall be entitled until, but only until, all Dividends accrued and unpaid on all shares of Preference Stock shall have been paid (or deposited in trust for payment on or before the next succeeding Dividend Payment Date with respect to shares of Preference Stock) to elect one (1) Director of the Corporation. (3) While the holders of the shares of Preference Stock remain entitled to elect one Director of the Corporation, the payment of Dividends on Preference Stock, including accrued and unpaid Dividends, shall not be unreasonably withheld if the financial condition of the Corporation permits payment thereof. (4) The right of the holders of the shares of Preference Stock under this Section (I) to elect one Director of the Corporation may be exercised at any annual meeting of shareholders or, within the limitations of this Section (I), at a special meeting of shareholders held for such purpose; whenever such right shall have become vested, upon request signed by any holder of record of shares of Preference Stock and delivered to the Corporation at its principal office not less than ninety (90) days prior to the date for the annual meeting next following the date of such vesting, the President of the Corporation shall call a special meeting of shareholders, to be held within sixty (60) days after the receipt of such request, for the purpose of electing a new Board of Directors, of which one shall, subject to the provisions of this Section (I), be elected by a vote of the holders of the shares of Preference Stock, to serve until the next annual meeting or until the successor of such Director shall be elected and shall qualify. (5) No such special meeting shall be required to be held within 120 days after such a prior special meeting, and the term of office of each Director of the Corporation shall terminate at the time of any such special meeting or adjournment thereof, notwithstanding that the term for which such Director had been elected shall not then have expired, and provided that the successor of such Director is duly elected and qualified. A-48 (6) In the event that at any special meeting at which the holders of the shares of Preference Stock shall be entitled to elect one Director of the Corporation, a quorum of the holders of the shares of Preference Stock shall not be present in person or by proxy, the holders of Common Stock, if a quorum thereof be present in person or by proxy, shall temporarily elect the Director of the Corporation, which the holders of the shares of Preference Stock were entitled but failed to elect, such Director to be designated as having been so elected and his or her term of office to expire at such time thereafter as his or her successor shall be elected by the holders of the shares of Preference Stock as provided in this Section (I).
