SECTION 3. Special Meetings. Special meetings of the stockholders for any purpose or purposes may be called at any time by the majority of the board of directors, the chief executive officer or the president, and only such persons as are specifically permitted to call meetings by the Minnesota Business Corporation Act in accordance with the provisions of the Corporation's Articles of Incorporation.

SECTION 4. Conduct of Meetings. Annual and special meetings shall be conducted in accordance with the rules and procedures established by the board of directors. The board of directors shall designate, when present, either the chairman of the board or president to preside at such meetings.

SECTION 5. Voting. At each election for directors every stockholder entitled to vote at such election shall be entitled to one vote for each share of stock held by him. Unless otherwise provided in the Articles of Incorporation, by Statute, or by these Bylaws, a majority of those votes cast by stockholders at a lawful meeting shall be sufficient to pass on a transaction or matter.

SECTION 6. Notice of Meetings. Written notice stating the place, day and hour of the meeting and the purpose or purposes for which the meeting is called shall be mailed by the secretary or the officer performing his duties, not less than ten days nor more than sixty days before the meeting to each stockholder of record entitled to vote at such meeting. If mailed, such notice shall be deemed to be delivered when deposited in the United States mail, addressed to the stockholder at his address as it appears on the stock transfer books or records of the Corporation as of the record date prescribed in Section 7 of this Article II, with postage thereon prepaid. If a stockholder is present at a meeting, or in writing waives notice thereof before or after the meeting, notice of the meeting to such stockholder shall be unnecessary. When any stockholders' meeting, either annual or special, is adjourned for 120 days, notice of the adjourned meeting shall be given as in the case of an original meeting. It shall not be necessary to give any notice of the time and place of any meeting adjourned for less than 120 days or of the business to be transacted at such adjourned meeting, other than an announcement at the meeting at which such adjournment is taken.

SECTION 7. Fixing of Record Date. For the purpose of determining stockholders entitled to notice of or to vote at any meeting of stockholders, or any adjournment thereof, or stockholders entitled to receive payment of any dividend, or in order to make a determination of stockholders for any other proper purpose, the board of directors shall fix in advance a date as the record date for any such determination of stockholders. Such date in any case shall be not more than sixty days, and in case of a meeting of stockholders, not less than ten days prior to the date on which the particular action, requiring such determination of stockholders, is to be taken. When a determination of stockholders entitled to vote at any meeting of stockholders has been made as provided in this section, such determination shall apply to any adjournment thereof.

SECTION 8. Quorum. A majority of the outstanding shares of the Corporation entitled to vote, represented in person or by proxy, shall constitute a quorum at a meeting of stockholders. If less than a majority of the outstanding shares are represented at a meeting, a majority of the shares so represented may adjourn the meeting from time to time without further notice. At such adjourned meeting at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the meeting as originally notified. The stockholders present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum.

SECTION 9. Proxies. A shareholder may cast or authorize the casting of a vote by filing a written appointment of a proxy with an officer of the Corporation at or before the meeting at which the appointment is to be effective. A written appointment of a proxy may be signed by the shareholder or authorized by the shareholder by transmission of a telegram, cablegram, or other means of electronic transmission, provided that the corporation has no reason to believe that the telegram, cablegram, or other electronic transmission was not authorized by the shareholder. Any reproduction of the writing or transmission may be substituted or used in lieu of the original writing or transmission for any purpose for which the original transmission could be used, provided that the copy, facsimile telecommunication, or other reproduction is a complete and legible reproduction of the entire original writing or transmission. Proxies solicited on behalf of the management shall be voted as directed by the stockholder or, in the absence of such direction, as determined by a majority of the board of directors. No proxy shall be valid after eleven months from the date of its execution unless otherwise provided in the proxy.

SECTION 10. Voting of Shares in the Name of Two or More Persons. When ownership of stock stands in the name of two or more persons, in the absence of written directions to the Corporation to the contrary, at any meeting of the stockholders of the Corporation any one or more of such stockholders may cast, in person or by proxy, all votes to which such ownership is entitled. In the event an attempt is made to cast conflicting votes, in person or by proxy, by the several persons in whose name shares of stock stand, the vote or votes to which these persons are entitled shall be cast as directed by a majority of those holding such stock and present in person or by proxy at such meeting, but no votes shall be cast for such stock if a majority cannot agree.

SECTION 11. Voting of Shares by Certain Holders. Shares standing in the name of another corporation may be voted by any officer, agent or proxy as the bylaws of such corporation may prescribe, or, in the absence of such provision, as the board of directors of such corporation may determine. Shares held by an administrator, executor, guardian trustee or conservator may be voted by him, either in person or by proxy, without a transfer of such shares into his name. Shares standing in the name of a receiver may be voted by such receiver, and shares held by or under the control of a receiver may be voted by such receiver without the transfer thereof into his name if authority to do so is contained in an appropriate order of the court or other public authority by which such receiver was appointed.

2

A stockholder whose shares are pledged shall be entitled to vote such shares until the shares have been transferred into the name of the pledgee and thereafter the pledgee shall be entitled to vote the shares so transferred.

Neither treasury shares of its own stock held by the Corporation, nor shares held by another corporation, if a majority of the shares entitled to vote for the election of directors of such other corporation are held by the Corporation, shall be voted at any meeting or counted in determining the total number of outstanding shares at any given time for purposes of any meeting.

SECTION 12. Inspectors of Election. In advance of any meeting of stockholders, the board of directors may appoint any persons, other than nominees for office, as inspectors of election to act at such meeting or any adjournment thereof. The number of inspectors shall be either one or three. If the board of directors so appoints either one or three inspectors, that appointment shall not be altered at the meeting. If inspectors of election are not so appointed, the chairman of the board or the president may make such appointment at the meeting. In case any person appointed as inspector fails to appear or fails or refuses to act, the vacancy may be filled by appointment by the board of directors in advance of the meeting or at the meeting by the chairman of the board or the president.

Unless otherwise prescribed by applicable law, the duties of such inspectors shall include: determining the number of shares of stock and the voting power of each share, the shares of stock represented at the meeting, the existence of a quorum, the authenticity, validity and effect of proxies; receiving votes, ballots or consents; hearing and determining all challenges and questions in any way arising in connection with the right to vote; counting and tabulating all votes or consents; determining the result; and such acts as may be proper to conduct the election or vote with fairness to all stockholders.

SECTION 13. Nominating Committee. The board of directors shall act as a nominating committee for selecting the management nominees for election as directors. Except in the case of a nominee substituted as a result of the death or other incapacity of a management nominee, the nominating committee shall deliver written nominations to the secretary at least twenty days prior to the date of the annual meeting. Provided such committee makes such nominations, no nominations for directors except those made by the nominating committee shall be voted upon at the annual meeting unless other nominations by stockholders are made in writing and delivered to the secretary of the Corporation in accordance with the provisions of the Corporation's Articles of Incorporation.

SECTION 8. Notice. Written notice of any special meeting shall be given to each director at least two days previous thereto delivered personally or by telegram or at least five days previous thereto delivered by mail at the address at which the director is most likely to be reached. Such notice shall be deemed to be delivered when deposited in the United States mail so addressed, with postage thereon prepaid if mailed or when delivered to the telegraph company if sent be telegram. Any director may waive notice of any meeting by a writing filed with the secretary. The attendance of a director at a meeting shall constitute a waiver of notice of such meeting, except where a director attends a meeting for the express purpose of objecting to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any meeting of the board of directors need be specified in the notice or waiver of notice of such meeting.

Each officer shall hold office until his successor shall have been duly elected and qualified or until his death or until he shall resign or shall have been removed in the manner hereinafter provided. Election or appointment of an officer, employee or agent shall not of itself create contract rights.

SECTION 8. Beneficial Owners. The Corporation shall be entitled to recognize the exclusive right of a person registered on its books as the owner of shares to receive dividends, and to vote as such owner, and shall not be bound to recognize any equitable or other claim to or interest in such shares on the part of any other person, whether or not the Corporation shall have express or other notice thereof, except as otherwise provided by law.
