A change in beneficial ownership of an outstanding share of common stock shall be deemed to have occurred whenever a change occurs in any person or group of persons who, directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise has or shares (i) voting power, which includes the power to vote, or to direct the voting of such share; (ii) investment power, which includes the power to direct the sale or other disposition of such share; (iii) the right to receive or retain the proceeds of any sale or other disposition of such share; or (iv) the right to receive any distributions, including cash dividends, in respect of such share. a.

For purposes of this paragraph B, all determinations concerning changes in beneficial ownership, or the absence of any such change, shall be made by the Corporation. Written procedures designed to facilitate such determinations shall be established by the Corporation and refined from time to time. Such procedures shall provide, among other things, the manner of proof of facts that will be accepted and the frequency with which such proof may be required to be renewed. The Corporation and any transfer agent shall be entitled to rely on all information concerning beneficial ownership of the common stock coming to their attention from any source and in any manner reasonably deemed by them to be reliable, but neither the Corporation nor any transfer agent shall be charged with any other knowledge concerning the beneficial ownership of the common stock. 5. In the event of any stock split or stock dividend with respect to the common stock, each share of common stock acquired by reason of such split or dividend shall be deemed to have been beneficially owned by the same person continuously from the same date as that on which beneficial ownership of the share of common stock, with respect to which such share of common stock was distributed, was acquired. 6. Each share of common stock, whether at any particular time the holder thereof is entitled to exercise five votes for one, shall be identical to all other shares of common stock in all other respects, and together all of the common shares shall constitute a single class of shares of the Corporation. 7.

Automated Quotation System (or such other similar automated quotation system as may exist at the time) so long as some but not all shares of common stock have five votes per share, then, upon a determination by the Board of Directors that the provisions of this paragraph B no longer are in the best interests of the shareholders, and without any shareholder action, each outstanding share of common stock shall entitle the holder thereof to one vote on each matter properly submitted thereafter to the holders of common stock for their vote, consent, waiver, release or other action. C. The preferences, voting rights, if any, limitations and relative rights of the serial preferred stock are as follows: 1. The holders of the preferred stock shall be entitled to receive dividends when and as declared by the Board of Directors at such rate as shall be fixed by resolution of the Board of Directors as hereafter provided, which dividends shall be cumulative, before any dividends shall be paid or set apart for payment on the common stock. The holders of the preferred stock shall have no rights to share in any dividend or distribution of profits or assets of the Corporation, whether in the form of cash, stock dividend or otherwise, except to the extent specifically provided herein or in said resolutions of the Board of Directors. 2. In the event of any liquidation, dissolution or winding up of the Corporation, the holders of the preferred stock shall be entitled to be paid such amounts as shall be fixed by resolution of the Board of Directors, as hereafter provided, before any amount shall be paid on the common stock. After the payment to the holders of the preferred stock of all such amounts to which they are entitled pursuant to said resolutions of the Board of Directors, the remaining assets and funds of the Corporation shall be divided and paid to the holders of common stock. Neither the consolidation nor the merger of the Corporation with or into any other corporation or corporations, nor a reorganization of the Corporation alone, nor the sale or transfer by the Corporation of all or any part of its assets, shall be deemed to be a liquidation, dissolution or winding up of the Corporation for the purpose of this subparagraph (2). 3. The preferred stock shall be subject to redemption in whole or in part at such price and at such time and place and in such manner as the Board of Directors shall determine. 4. Each share of preferred stock shall be entitled to such privileges of conversion, if any, as are provided and declared by the Board of Directors at such time as the issue of which it is a part is established by the Board of Directors.

Authority is hereby expressly granted to the Board of Directors to authorize one or more series of preferred stock and to fix the number of shares to constitute such series and distinctive designations thereof and, with respect to each series of preferred stock, to fix by resolution or resolutions providing for the issuance of such series such variations in respect thereof as may be determined by the Board of Directors. All shares of every series of preferred stock shall be alike in every particular, and all series of preferred stock hereafter created shall rank equally and be identical in all respects, except as to the following rights and preferences which may constitute variations as between different series of preferred stock: a. The rate of the dividend on the shares of such series; b. The price at, and the terms and conditions upon which shares may be redeemed; c. The amount payable upon shares in the event of involuntary liquidation; d. The amount payable upon shares in the event of voluntary liquidation; e.

ARTICLE V A. The number of directors of the Corporation shall be not less than twelve (12) and not greater than sixteen (16), and, effective as of the annual meeting of shareholders in 1982, the Board of Directors shall be divided into three classes, designated Class I, Class II and Class III. Such classes shall be as nearly equal in number as possible. The term of directors of one class shall extend to each annual meeting of shareholders and in all cases as to each director, until his successor shall be elected and shall qualify, or until his earlier resignation, removal from office, death or incapacity. Additional directorships resulting from an increase in number of directors shall be apportioned among the classes as equally as possible. The initial term of office of directors of Class I shall extend to the annual meeting of shareholders in 1983, that of Class II shall extend to the annual meeting in 1984, and that of Class III shall extend to the annual meeting in 1985, and in all cases as to each director until his successor shall be elected and shall qualify or until his earlier resignation, removal from office, death or incapacity. At each annual meeting of shareholders, the number of directors equal to the number of directors of the class whose term extends to the time of such meeting shall be elected to hold office until the third succeeding annual meeting of shareholders after their election. The Board of Directors may, upon a majority vote of its members, increase or decrease the number of directors within the limits set forth above. Vacancies in the Board of Directors or new directorships created by an increase in the number of directors shall be filled by majority vote of the remaining members of the Board and the person filling such vacancy or newly-created directorship shall serve out the remainder of the term for the vacated directorship or, in the case of a new directorship, the term designated for the class of directors of which that directorship is a part. B. The shareholders may at any time at a meeting expressly called for that purpose remove any or all of the directors, only for cause, by a vote of two-thirds of the shares then entitled to vote at an election of directors. For purposes of this Article, removal "for cause" shall mean that the director to be removed has been convicted of a felony by a court of competent jurisdiction and such conviction is no longer subject to direct appeal, or that the director to be removed has been adjudged to be liable for negligence or misconduct in the performance of his duty to the Corporation by a court of competent jurisdiction and such adjudication is no longer subject to direct appeal. C. This Article V may not be amended, altered or repealed without the approval of two-thirds of the shares entitled to vote at the time such amendment, alteration or repeal is proposed. ARTICLE VI The Board of Directors of this Corporation shall have the power to adopt a corporate seal which shall be the corporate seal of this Corporation. ARTICLE VII The private property of the shareholders of this Corporation shall at all times be exempt from liability of corporate debts of any kind and this Article shall not be amended or repealed. ARTICLE VIII In the event that any shareholder shall become indebted to the Corporation, the Corporation shall have a lien upon any shares of stock in this Corporation owned by such shareholder for the full amount of such indebtedness. ARTICLE IX Stock in this Corporation shall be transferred only by assignment upon the books of the Corporation, subject to and in accordance with such restrictions as may be provided in the by-laws of this Corporation. ARTICLE X To the fullest extent permitted by the Iowa Business Corporation Act as the same now exists or may hereafter be amended, a director of the Corporation shall not be liable to the Corporation or its stock-holders for monetary damages for breach of fiduciary duty as a director. Any repeal or modification of this ARTICLE X by the stockholders of the Corporation only shall be applied prospectively, to the extent that such repeal or modification would, if applied retrospectively, adversely affect any limitation on the personal liability of a director of the Corporation existing immediately prior to such repeal or modification. The above Third Restated and Amended Articles of Incorporation do not contain an amendment requiring the approval of the Corporation's shareholders, and were unanimously adopted by the Corporation's Board of Directors on September 9, 1996.

Designation and Amount. (a) There shall be a series of Preferred Stock of the Corporation created out of the authorized but unissued shares of the capital stock of the Corporation, which series shall be designated Series A Junior Participating Preferred Stock (the "Participating Preferred Stock"), to consist of one hundred and fifty thousand (150,000) shares, without par value. (b) Subject of paragraph 4(e) of this designation, the number of shares of said series may at any time or from time to time be increased or decreased by the Board of Directors notwithstanding that shares of such series may be outstanding at such time of increase or decrease. 2. Dividend Rate. (a) The holders of shares of Participating Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the purpose, quarterly dividends payable in cash on the first day of each November, February, May and August in each year (each such date being referred to herein as a "Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Participating Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $230.00 or (b) 1,000 times the aggregate per share amount of all cash dividends and 1,000 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared on the Common Stock, par value of One Dollar ($1.00) per share, of the Corporation (the "Common Stock") since the immediately preceding Quarterly Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Participating Preferred Stock. (b) On or after the first issuance of any share or fractional share of Participating Preferred Stock, no dividend on Common Stock shall be declared unless concurrently therewith a dividend or distribution is declared on the Participating Preferred Stock as provided in paragraph (a) above; and the declaration of any such dividend on the Common Stock shall be expressly conditioned upon payment or declaration of and provision for a dividend on the Participating Preferred Stock as above provided. In the event no dividend or distribution shall have been declared on the Common Stock during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a dividend of $230.00 per share on the Participating Preferred Stock shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date. (c) Dividends shall begin to accrue and be cumulative on outstanding shares of Participating Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares of Participating Preferred Stock, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of Participating Preferred Stock entitled to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. The Board of Directors may fix a record date for the determination of holders of shares of Participating Preferred Stock entitled to receive payment of a dividend distribution declared thereon, which record date shall be no more than 30 days prior to the date fixed for the payment thereof. 3. Dissolution. Liquidation and Winding Up. In the event of any voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Corporation (hereinafter referred to as a "Liquidation"), the holders of Participating Preferred Stock shall receive at least $1,000.00 per share, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment, provided that the holders of shares of Participating Preferred Stock shall be entitled to receive at least an aggregate amount per share equal to 1,000 times the aggregate amount to be distributed per share to holders of Common Stock (the "Participating Preferred Liquidation Preference"). 4. Voting Rights. The holders of shares of Participating Preferred Stock shall have the following voting rights: (a) Each share of Participating Preferred Stock shall entitle the holder thereof to five thousand (5,000) votes on all matters submitted to a vote of the stockholders of the Corporation, except that no holder of Participating Preferred Stock shall be entitled to exercise more than one thousand (1,000) votes on any such matter in respect of any share of Participating Preferred Stock if such holder would have been entitled to exercise no more than one vote on any such matter in respect of any share of Common Stock under Article IV.B of the Articles of Incorporation, had such shares of Participating Preferred Stock been shares of Common Stock. (b) Except as otherwise provided herein, or by law, the Articles of Incorporation or the By-laws of the Corporation, the holders of shares of Participating Preferred Stock and the holders of shares of Common Stock shall vote together as one class on all matters submitted to a vote of stockholders of the Corporation. (c) If and whenever dividends on the Participating Preferred Stock shall be in arrears in an amount equal to six quarterly dividend payments, then and in such event the holders of the Participating Preferred Stock, voting separately as a class (subject to the provisions of subparagraph (d) below), shall be entitled at the next annual meeting of the stockholders or at any special meeting to elect two (2) directors. Each share of Participating Preferred Stock shall be entitled to one vote, and holders of fractional shares shall have the right to a fractional vote. Upon election, such directors shall become additional directors of the Corporation and the authorized number of directors of the Corporation shall thereupon be automatically increased by such number of directors. Such right of the holders of Participating Preferred Stock to elect directors may be exercised until all dividends in default on the Participating Preferred Stock shall have been paid in full, and dividends for the current dividend period declared and funds therefor set apart, and when so paid and set apart, the right of the holders of Participating Preferred Stock to elect such number of directors shall cease, the term of such directors shall thereupon terminate, and the authorized number of directors of the Corporation shall thereupon return to the number of authorized directors otherwise in effect, but subject always to the same provisions for the vesting of such special voting rights in the case of any such future dividend default or defaults. The fact that dividends have been paid and set apart as required by the preceding sentence shall be evidenced by a certificate executed by the President and the chief financial officer of the Corporation and delivered to the Board of Directors. The directors so elected by holders of Participating Preferred Stock shall serve until the certificate described in the preceding sentence shall have been delivered to the Board of Directors or until their respective successors shall be elected or appointed and qualify. At any time when such special voting rights have been so vested in the holders of the Participating Preferred Stock, the Secretary of the Corporation may, and upon the written request of the holders of record of 10% or more of the number of shares of the Participating Preferred Stock then outstanding addressed to such Secretary at the principal office of the Corporation in the State of Iowa, shall, call a special meeting of the holders of the Participating Preferred Stock for the election of the directors to be elected by them as hereinabove provided, to be held in the case of such written request within forty (40) days after delivery of such request, and in either case to be held at the place and upon the notice provided by law and in the By-laws of the Corporation for the holding of meetings of stockholders; provided, however that the Secretary shall not be required to call such a special meeting (i) if any such request is received less than ninety (90) days before the date fixed for the next ensuing annual or special meeting of stockholders or (ii) if at the time any such request is received, the holders of Participating Preferred Stock are not entitled to elect such directors by reason of the occurrence of an event specified in the third sentence of subparagraph (d) below. (d) if; at any time when the holders of Participating Preferred Stock are entitled to elect directors pursuant to the foregoing provisions of this paragraph 4, the holders of any one or more additional series of Preferred Stock are entitled to elect directors by reason of any default or event specified in the Articles of Incorporation, as in effect at the time of the designation for such series, and if the terms for such other additional series so permit, the voting rights of the two or more series then entitled to vote shall be combined (with each series having a number of votes proportional to the aggregate liquidation preference of its outstanding shares). In such case, the holders of Participating Preferred Stock and of all such other series then entitled so to vote, voting as a class, shall elect such directors. If the holders of any such other series have elected such directors prior to the happening of the default or event permitting the holders of Participating Preferred Stock to elect directors, or prior to a written request for the holding of a special meeting being received by the Secretary of the Corporation from the holders of not less than 10% of the then outstanding shares of Participating Preferred Stock, then such directors so previously elected will be deemed to have been elected by and on behalf of the holders of Participating Preferred Stock as well as such other series, without prejudice to the right of the holders of Participating Preferred Stock to vote for directors if such previously elected directors shall resign, cease to serve or fail to stand for reelection while the holders of Participating Preferred Stock are entitled to vote. If the holders of any such other series are entitled to elect in excess of two (2) directors, the Participating Preferred Stock shall not participate in the election of more than two (2) such directors, and those directors whose terms first expire shall be deemed to be the directors elected by the holders of Participating Preferred Stock; provided that, if at the expiration of such terms the holders of Participating Preferred Stock are entitled to vote in the election of directors pursuant to the provisions of this paragraph 4, then the Secretary of the Corporation shall call a meeting (which meeting may be the annual meeting or special meeting of stockholders referred to in subparagraph (c)) of holders of Participating Preferred Stock for the purpose of electing replacement directors (in accordance with the provisions of this paragraph 4) to be held on or prior to the time of expiration of the expiring terms referred to above. (e) Except as otherwise set forth herein or required by law, the Articles of Incorporation or the By-laws of the Corporation, holders of Participating Preferred Stock shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for the taking of any corporate action. No consent of the holders of outstanding shares of Participating Preferred Stock at any time outstanding shall be required in order to permit the Board of Directors to: (i) increase the number of authorized shares of Participating Preferred Stock or to decrease such number to a number not below the sum of the number of shares of Participating Preferred Stock then outstanding and the number of shares with respect to which there are outstanding rights to purchase; or (ii) to issue Preferred Stock which is senior to the Participating Preferred Stock, junior to the Participating Preferred Stock or on a parity with the Participating Preferred Stock. 5. Redemption. The shares of Participating Preferred Stock shall not be redeemable. 6. Conversion Rights. The Participating Preferred Stock is not convertible into Common Stock or any other security of the Corporation.

If the assets of the Corporation are not sufficient to pay in full the liquidation payments payable to all of the Holders of the outstanding shares of Class B Common Stock, then the Holders of all such shares shall share ratably in such distribution of assets in accordance with the liquidation preference to which they are entitled. For the purposes of this section, neither the voluntary sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property or assets of the Corporation nor the consolidation or merger of the Corporation with one or more other corporations shall be deemed to be a liquidation, dissolution or winding up, voluntary or involuntary, unless such voluntary sale, conveyance, exchange or transfer shall be in connection with a dissolution or winding up of the business of the Corporation. 5.

(iii) At any time that all outstanding shares of Common Stock (or whatever security received upon conversion or exchange thereof) have the same vote per share, if any, without any time-phased voting, all shares of Class B Common Stock shall be convertible into fully-paid and non-assessable shares of Common Stock, with each such share of Class B Common Stock being converted into one share of Common Stock (as adjusted pursuant to Section 6(c)). (iv) Except as set forth in this Section 6(a), the shares of Class B Common Stock are not convertible at the option of the Holder thereof. (b) (i) Any Holder of shares of Class B Common Stock required (or in the case of clause (iii) above requesting) to convert any or all such shares into Common Stock shall surrender the certificate(s) evidencing such shares of Class B Common Stock of the Holder at the office of the transfer agent appointed for the purpose of such conversion by the Corporation. Such surrendered certificate(s), if the Corporation shall so require, shall be duly endorsed to the Corporation or in blank, or accompanied by proper instruments of transfer to the Corporation or in blank.

Such conversion shall be deemed to have been made on the date of such surrender of the certificate(s) evidencing shares of Class B Common Stock to be converted (the "Surrender Date") and the Person(s) entitled to receive the Common Stock deliverable upon conversion of such Class B Common Stock shall be treated for all purposes as the record holder(s) of such Common Stock on such date and thereafter. Conversion of Class B Common Stock may otherwise be achieved in accordance with such procedures as the Corporation and a majority of the Holders may agree. (iii) In the event that fewer than all shares of Class B Common Stock represented by a surrendered certificate are to be converted hereunder, a new certificate shall be issued at the Corporation's expense representing the shares of Class B Common Stock not so converted. (iv) In connection with the conversion of any shares of Class B Common Stock, no fractions of shares of Common Stock shall be issued, but in lieu thereof the Corporation shall pay a cash adjustment in respect of such fractional interest in an amount equal to such fractional interest multiplied by the Market Price (as defined in the Investment Agreement) per share of Common Stock on the day on which such shares of Class B Common Stock are deemed to have been converted. (c) The conversion rate shall be adjusted from time to time as follows: (i) In case the Corporation shall, at any time or from time to time while any of the shares of Class B Common Stock are outstanding, (A) subdivide or reclassify its outstanding shares of Common Stock into a larger number of shares (including a subdivision effected by declaring and paying a Dividend payable in additional shares of Common Stock), or (B) combine or reclassify its outstanding shares of Common Stock into a smaller number of shares, the conversion rate in effect immediately prior to such action shall be adjusted so that the Holder of any shares of Class B Common Stock thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock which such Holder would have owned or have been entitled to receive immediately following such action had such shares of Class B Common Stock been converted immediately prior thereto (which adjustments shall be in lieu of payment of any Dividend on the Class B Common Stock); provided that no adjustment pursuant to this Section 6 (c)(i) shall be made in connection with a subdivision, combination or reclassification (including by way of a Dividend payable in additional shares of Common Stock) described above if the Corporation shall concurrently therewith subdivide, combine or reclassify (including by way of a Dividend payable in additional shares of Class B Common Stock) the outstanding Class B Common Stock on the same basis as the Common Stock is so subdivided, combined or reclassified. An adjustment made pursuant to this Section 6(c)(i) shall become effective immediately after the close of business on the effective date of a subdivision, reclassification or combination. If, as a result of an adjustment made pursuant to this Section 6(c)(i), the Holder of any shares of Class B Common Stock thereafter surrendered for conversion shall become entitled to receive shares of two or more classes of capital stock of the Corporation, the Board of Directors shall make an appropriate allocation of the adjusted conversion rate between or among shares of such classes of capital stock in accordance with the entitlements of the Common Stock underlying the Class B Common Stock in connection with such adjustment. (ii) Whenever an adjustment in the conversion rate is required, the Corporation shall forthwith place on file with its Transfer Agent a statement signed by its Chief Executive Officer, Chief Financial Officer or a Vice President and by its Secretary, Assistant Secretary, Treasurer or Assistant Treasurer, stating the adjusted conversion rate determined as provided herein. Such statements shall set forth in reasonable detail such facts as shall be necessary to show the reason and the manner of computing such adjustment. (iii) In the event that prior to the issuance of the Class B Common Stock the Company shall (A) subdivide or reclassify its outstanding shares of Common Stock into a larger number of shares (including a subdivision effected by declaring or paying a Dividend payable in additional shares of Common Stock) or (B) combine or reclassify its outstanding shares of Common Stock into a smaller number of shares, the conversion ratio applicable to the Class B Common Stock shall be appropriately adjusted. (d) (i) The Corporation shall at all times reserve and keep available, free from preemptive rights, out of its authorized and unissued stock, such number of shares of its Common Stock as shall from time to time be sufficient to effect the conversion of all shares of Class B Common Stock from time to time outstanding, solely for the purpose of effecting such conversion. The Corporation shall, from time to time, in accordance with the laws of the State of Iowa, increase the authorized number of shares of Common Stock if at any time the number of shares of authorized and unissued Common Stock shall not be sufficient to permit the conversion of all the then outstanding shares of Class B Common Stock. (ii) The Corporation will pay any and all stamp and transfer taxes that may be payable in respect of the issuance or delivery of shares of Common Stock upon conversion of shares of Class B Common Stock pursuant hereto. The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Common Stock in a name other than that in which the shares of Class B Common Stock so converted were registered and no such issuance or delivery shall be made unless and until the person requesting such issuance has paid to the Corporation the amount of any such tax or has established to the satisfaction of the Corporation that such tax has been paid. (e) In case of (i) any reclassification or change of outstanding shares of Common Stock (other than a change in par value or from par value to no par value or from no par value to par value, or as a result of a subdivision or combination) or (ii) any consolidation or merger of the Corporation with one or more other corporations (other than a consolidation or merger in which the Corporation is the continuing corporation and which does not result in any reclassification or change of outstanding shares of Common Stock issuable upon conversion of Class B Common Stock) or (iii) any sale or conveyance to another corporation or other entity of all or substantially all of the property of the Corporation, then the Corporation, or such successor corporation or other entity, as the case may be, shall make appropriate provision so that the holder of each share of Class B Common Stock then outstanding shall have the right to convert such share into the kind and amount of shares of stock or other securities and property receivable upon such consolidation, merger, sale, reclassification, change or conveyance by a holder of the number of shares of Common Stock into which such shares of Class B Common Stock might have been converted immediately prior to such consolidation, merger, sale, reclassification, change or conveyance, subject to adjustment which shall be as nearly equivalent as may be practicable to the adjustments provided for in Section 6(c)(to the extent adjustment would be required pursuant to Section 6(c) above). If the holders of Common Stock are entitled to elect the consideration payable pursuant to any consolidation, merger, sale, conveyance or other transaction or event set forth above, the Holders also shall be entitled to elect between such forms of consideration. The provisions of this paragraph shall apply similarly to successive consolidations, mergers, sales, conveyances or other transactions or events. (f) Whenever the number of shares of Common Stock into which each share of Class B Common Stock is convertible is adjusted as provided in this Section 6, the Corporation shall promptly mail to the Holders a notice in accordance with Section 8 below stating that the number of shares of Common Stock into which the shares of Class B Common Stock are convertible has been adjusted and setting forth the new number of shares of Common Stock (or describing the new stock, securities, cash or other property) into which each share of Class B Common Stock is convertible, as a result of such adjustment, a brief statement of the facts requiring such adjustment and the computation thereof, and when such adjustment became effective. 7.
