DIVISION I

Provisions Relating to Cumulative Preferred Shares

A.Issue in Series. The Cumulative Preferred Shares may be issued from time to time in one or more series, each of which series shall have such designation and such relative rights, voting power, preferences and restrictions as are hereinafter provided and, to the extent hereinafter permitted, as are determined and stated by the Board of Directors in the resolution or resolutions authorizing the creation of shares of such series.

All Cumulative Preferred Shares shall be of equal rank and shall be identical, except in respect of their relative voting power (determined as hereinafter provided in Division IV) and the particulars that may be determined by the Board of Directors as hereinafter provided; and each share of each series shall be identical in all respects with the other shares of such series, except

– 2 –

as to the dates from which dividends thereon shall be cumulative. Cumulative Preferred Shares shall be issued only as fully paid and nonassessable shares.

Subject to the provisions of the last paragraph of this Subdivision A, authority is hereby expressly granted to the Board of Directors to authorize the issuance of Cumulative Preferred Shares in one or more series, and to determine and state, by the resolution or resolutions authorizing the creation of each series: (i) the designation of the series and the number of shares which shall constitute such series, which number may be altered from time to time by like action of the Board of Directors in respect of shares then unallotted;

(ii) the annual rate of dividends payable on shares of such series; (iii) the price or prices per share at which the shares of such series shall be redeemable; (iv) the amount payable on shares of such series in the event of any dissolution, liquidation or winding up of the affairs of the corporation, which amount may differ in the case of a voluntary or involuntary dissolution, liquidation or winding up of such affairs; (v) the conversion rights, if any, with respect to the conversion of shares of such series into Common Shares of the corporation; and (vi) the sinking or purchase fund provisions, if any, for the mandatory redemption or purchase of shares of such series.

In the case of each series of Cumulative Preferred Shares created after April 1, 1977, the amount (in addition to accrued and unpaid dividends, if any) which the holders of shares of such series shall be entitled to receive in the event of any dissolution, liquidation or winding up of the affairs of the corporation which shall be involuntary shall be equal to the gross consideration received by the corporation upon the issuance thereof (without regard to any premium received or any underwriting discount or commission, private placement fee or other expense incurred by the corporation in connection with the issuance thereof).

B.Dividends. Before any dividends on any subordinate shares shall be paid or declared and set apart for payment, the holders of the Cumulative Preferred Shares of each series shall be entitled to receive, when and as declared by the Board of Directors, out of any funds legally available for such purpose, cash dividends at the annual rate for such series theretofore fixed by the Board of Directors as hereinbefore provided, and no more, payable quarterly on such dates as may be fixed in the resolution or resolutions adopted by the Board of Directors authorizing the creation of such series. Such dividends shall be paid to shareholders of record on the respective dates, not exceeding twenty (20) days prior to such payment dates, fixed by the Board of Directors for such purpose. Such dividends shall be cumulative, in the case of shares of each particular series:

(1) if issued prior to the record date for the first dividend on shares of such series, then from and including the date fixed for such purpose by the Board of Directors in the resolution or resolutions creating such series;

(2) if issued during the period commencing immediately after the record date for a dividend on shares of such series and terminating at the close of the payment date for such dividend, then from and including such last mentioned dividend payment date;

(3) otherwise from and including the quarterly dividend payment date next preceding the date of issue of such shares.

– 3 –

No dividend shall be paid, or declared and set apart for payment, upon any Cumulative Preferred Shares of any series for any quarterly dividend period unless at the same time a like proportionate dividend for the same or comparable quarterly period, ratable in proportion to the respective annual dividend rates fixed therefor, shall be paid, or declared and set apart for payment, upon all Cumulative Preferred Shares of all series then issued and outstanding.

In no event shall any dividend be paid or declared, nor shall any distribution be made, on any subordinate shares, nor shall any subordinate shares be purchased, redeemed or otherwise acquired by the corporation for value, nor shall any moneys be paid to or set aside or made available for a purchase fund or sinking fund for the purchase or redemption of any subordinate shares, unless (i) all dividends on the Cumulative Preferred Shares of all series for all past quarterly dividend periods and for the then current quarterly dividend period shall have been paid or declared and a sum sufficient for the payment thereof set apart for payment; and (ii) the corporation shall not be in default or deficient under any requirement of a sinking or purchase fund established with respect to outstanding Cumulative Preferred Shares of any series for any period then elapsed.

Subject to the provisions of this Article VI, and not otherwise, dividends may be declared by the Board of Directors and paid from time to time, out of any funds legally available therefor, upon the then outstanding subordinate shares, and the holders of the Cumulative Preferred Shares shall not be entitled to participate in any such dividends.

C.Redemption of Cumulative Preferred Shares. Subject to the limitations stated in Subdivision D of this Division I, the Cumulative Preferred Shares of any or all series may be redeemed, as a whole at any time or in part from time to time, at the option of the corporation by resolution of the Board of Directors, at the applicable redemption price for the shares of such series as determined by the Board of Directors in the resolution or resolutions authorizing the creation of such series, together with an amount (hereinafter referred to as “accrued dividends to the redemption date”) in the case of each share, computed at the annual dividend rate for the series of which the particular share is a part, from and including the date on which dividends on such shares become cumulative to and including the date of redemption, less the aggregate amount of all dividends which have theretofore been paid thereon or which have been declared thereon and for which moneys for payment have been set apart and remain available for payment. To the extent that Cumulative Preferred Shares of any series are redeemed through the operation of a sinking or purchase fund provided for in the resolution or resolutions of the Board of Directors creating such series, such shares shall be redeemed by resolution of the Board of Directors at the time and at the applicable redemption price specified for redemption of shares of such series pursuant to such sinking or purchase fund by the resolution or resolutions creating such series. If less than all the outstanding Cumulative Preferred Shares of any series are to be redeemed, the shares to be redeemed shall be determined by lot in such manner as the Board of Directors may prescribe.

Notice of every redemption of Cumulative Preferred Shares shall be mailed, addressed to the holders of record of the shares to be redeemed at their respective addresses as they shall appear on the stock books of the corporation, not less than thirty (30) days and not more than sixty (60) days prior to the date fixed for redemption.

– 4 –

If notice of redemption shall have been duly given as aforesaid, and if, on or before the redemption date specified in the notice, all funds necessary for the redemption shall have been deposited in trust with a bank or trust company in good standing and doing business at any place within the United States, having capital, surplus and undivided profits aggregating at least $1,000,000 and designated in the notice of redemption, for the pro rata benefit of the holders of the shares so called for redemption, so as to be and continue to be available therefor, then from and after the date of such deposit, notwithstanding that any certificate for Cumulative Preferred Shares so called for redemption shall not have been surrendered for cancellation, the shares represented thereby shall no longer be deemed outstanding, the dividends thereon shall cease to accumulate from and after the date fixed for redemption, and all rights with respect to the Cumulative Preferred Shares so called for redemption shall forthwith on the date of such deposit cease and terminate, except only the right of the holders thereof to receive the redemption price of the shares so redeemed, including accrued dividends to the redemption date, but without interest. Any funds deposited by the corporation pursuant to this paragraph and unclaimed at the end of six (6) years after the date fixed for redemption shall be repaid to the corporation upon its request expressed in a resolution of its Board of Directors, after which repayment the holders of the shares so called for redemption shall look only to the corporation for the payment thereof.

All Cumulative Preferred Shares converted, redeemed or purchased voluntarily or pursuant to any sinking fund or purchase fund for the mandatory redemption or purchase of shares shall be retired and cancelled and shall have the status of authorized but unissued Cumulative Preferred Shares of the corporation and may be reissued in the same manner as authorized but unissued Cumulative Preferred Shares undesignated as to series.

D.Limitations on Purchase and Redemption of Cumulative Preferred Shares. No Cumulative Preferred Shares of any series shall be purchased, redeemed or otherwise acquired by the corporation for value, nor shall any moneys be paid to or set aside or made available for a purchase fund or sinking fund for the purchase or redemption of Cumulative Preferred Shares of any series, unless all dividends on the Cumulative Preferred Shares of all series for all past quarterly dividend periods and for the current quarterly period shall have been paid or declared and a sum sufficient for the payment thereof set apart for payment, except in the event all of the Cumulative Preferred Shares shall be called for redemption.

E.Liquidation Preferences. In the event of any dissolution, liquidation or winding up of the affairs of the corporation, before any distribution or payment shall be made to the holders of any subordinate shares, the holders of the shares of each series of Cumulative Preferred Shares shall be entitled to be paid in full the respective amounts fixed by the Board of Directors in the resolution or resolutions authorizing the issue of such series, together with a sum, in the case of each share, computed at the annual dividend rate for the series of which the particular share is a part, from the date on which dividends on such shares became cumulative to and including the date fixed for such distribution or payment, less the aggregate amount of all dividends which have theretofore been paid thereon or which have been declared thereon and for which moneys have been set apart and remain available for payment. If such distribution or payment shall have been made to the holders of the Cumulative Preferred Shares, or moneys made available for such payment in full, the remaining assets and funds of the corporation shall be distributed among the holders of the classes of subordinate shares, according to their respective rights and preferences and in each case according to their respective shares. If the

– 5 –

assets available are not sufficient to pay in full the amounts so payable to the holders of all outstanding Cumulative Preferred Shares, the holders of all series of such shares shall share ratably in any distribution of assets in proportion to the full amounts to which they would otherwise be respectively entitled. The consolidation or merger of the corporation into or with any other corporation or corporations pursuant to the statutes of the State of Minnesota providing for consolidation or merger shall not be deemed a liquidation, dissolution or winding up of the affairs of the corporation within the meaning of any of the provisions of this Subdivision E.

All Cumulative Preference Shares converted, redeemed or purchased voluntarily or pursuant to any sinking fund or purchase fund for the mandatory redemption or purchase of shares shall be retired and cancelled and shall have the status of authorized but unissued Cumulative Preference Shares of the corporation and may be reissued in the same manner as authorized but unissued Cumulative Preference Shares undesignated as to series.

– 17 –

director with respect to whom the vacancy occurred by a majority of the remaining directors of the Board of Directors, although less than a quorum, and (d) vacancies in the Board of Directors occurring by reason of newly created directorships resulting from an increase in the authorized number of directors by action of the Board of Directors as permitted by these Articles of Incorporation and the Bylaws of the corporation shall be filled by a majority vote of the directors serving at the time of such increase, each director so elected to a newly created directorship to serve for the appropriate term so as to maintain, as near as may be, an equal division between the classes of directors. Notwithstanding any other provisions of these Articles of Incorporation or the Bylaws of the corporation or the fact that a lesser percentage may be specified by law, these Articles of Incorporation or the Bylaws of the corporation, the affirmative vote of the holders of at least 75% of the voting power of the then outstanding Common Shares shall be required to amend, alter, adopt any provision inconsistent with or repeal this paragraph (1) of Subdivision E of this Division IV unless the Board of Directors, if all such directors are Continuing Directors, as defined in this Article VI, shall unanimously recommend such amendment, alteration, adoption or repeal.

(2) If at any time the holders of Cumulative Preferred Shares and/or Cumulative Preference Shares of the corporation shall, under the provisions of paragraph (1) of Subdivision B of this Division IV or of paragraph (1) of Subdivision C of this Division IV, become entitled to elect any directors, then the terms of all incumbent directors shall expire at the time of the first annual meeting thereafter at which such holders of Cumulative Preferred Shares and/or Cumulative Preference Shares are so entitled to elect directors. If at any time the holders of Cumulative Preferred Shares of the corporation shall, under the provisions of paragraph (2) of Subdivision B of this Division IV, become entitled to elect a majority of the Board of Directors, the terms of all incumbent directors shall expire whenever such majority has been duly elected and qualified. During any period during which the holders of Cumulative Preferred Shares and/or Cumulative Preference Shares of the corporation shall have voting rights with respect to directors under the provisions of this Division IV, the Board of Directors shall consist of eleven (11) persons and the entire number of persons composing such Board shall be elected at each annual or special meeting of shareholders for the election of directors and shall serve until the next such annual or special meeting or until their successors have been elected and qualified, provided, however, that whenever the holders of Cumulative Preferred Shares and/or Cumulative Preference Shares acquire voting rights under paragraph

(1) of Subdivision B of this Division IV or under paragraph (1) of Subdivision C of this Division IV, and exercise such rights at a special meeting called therefor, the terms of office of directors theretofore elected by the holders of Common Shares will not expire until the next annual meeting.

Likewise, if a vacancy or vacancies shall exist with respect to a director or directors who shall have been elected by the holders of Common Shares, the

– 18 –

remaining directors elected by the holders of Common Shares, by affirmative vote of a majority thereof, or the remaining director so elected if there be but one, may elect a successor or successors to hold office for the unexpired term of the director or directors whose place or places shall be vacant.

A special meeting shall be called for such purpose within twenty (20) days after the written request therefor signed by the holders of not less than five percent (5%) of the Common Shares outstanding, the date of such special meeting to be not more than forty

(40)days from the date of giving of notice thereof. Upon the election and qualification of directors by the holders of Common Shares as aforesaid the provisions of paragraph (1) of Subdivision E of this Division IV shall again control, unless at that time the holders of Cumulative Preference Shares have voting rights for the election of directors.

(4) Whenever the Cumulative Preference Shares shall be divested of voting powers with respect to the election of directors as provided in paragraph (2) of Subdivision C of this Division IV, the terms of all incumbent directors, other than directors elected by the holders of Cumulative Preferred Shares pursuant to Subdivision B of this Division IV, shall expire on the election of their successors by the holders of the Common Shares at the next annual or special meeting of shareholders for the election of directors. A special meeting shall be called for such purpose within twenty (20) days after the written request therefor signed by the holders of not less than five percent (5%) of the Common Shares outstanding, the date of such special meeting to be not more than forty

(40) days from the date of giving of notice thereof. Upon the election and qualification of directors by the holders of Common Shares as aforesaid, the provisions of paragraph (1) of Subdivision E of this Division IV shall again control, unless at that time the holders of Cumulative Preferred Shares have voting rights for the election of directors.

F.Cumulative Voting. The holders of Common Shares of the corporation shall have no right to cumulate votes in the election of directors. If notice in writing is given by any holder of Cumulative Preferred Shares or Cumulative Preference Shares to any officer of the corporation before a meeting for the election of directors at which such shareholder is entitled to vote, or to the presiding officer at such meeting at any time before the election of directors takes place, that he intends to cumulate his votes in such election, each holder of shares of the class with respect to which such notice has been given shall have the right to multiply the number of votes to which he may be entitled by the number of directors to be elected by the holders of shares of such class, and he may cast all such votes for one candidate or distribute them among any two or more candidates. In such case, it shall be the duty of the presiding officer, before the election of directors at the meeting, to announce that all shareholders of the class with respect to which such notice has been given shall cumulate their votes.

– 19 –

G.Preemptive Rights. No holder of shares of the corporation of any class or of any security or obligation convertible into, or of any warrant, option or right to purchase, subscribe for or otherwise acquire, shares of any class of the corporation, whether now or hereafter authorized, shall, as such holder, have any preemptive or preferential right whatsoever to purchase, subscribe for or otherwise acquire shares of any class of the corporation or of any security or obligation convertible into, or of any warrant, option or right to purchase, subscribe for or otherwise acquire, shares of any class of the corporation, whether now or hereafter authorized, other than such rights of subscription, if any, as the Board of Directors may from time to time determine.
