     Section 2.03. Special Meetings. Special meetings of the shareholders may be held at any time and for any purpose and may be called by the President, Treasurer, any two or more directors, or by one or more shareholders holding 10% or more of the shares entitled to vote on the matters to be presented to the meeting.

In case a quorum shall not be present at a meeting, those present may adjourn the meeting to such day as they shall, by majority vote, agree upon, and a notice of such adjournment and the date and time at which such meeting shall be reconvened shall be mailed to each shareholders entitled to vote at least 5 days before such reconvened meeting. If a quorum is present, a meeting may be adjourned from time to time without notice other than announcement at the meeting. At adjourned meetings at which a quorum is present, any business may be transacted which might have been transacted at the meeting as originally noticed. If a quorum is present, the shareholders may continue to transact business until adjournment notwithstanding of the withdrawal of enough shareholders to leave less than a quorum.

     Section 2.05. Voting. At each meeting of the shareholders every shareholder having the right to vote shall be entitled to vote either in person or by proxy.

A shareholder, by his attendance at any meeting of shareholders, shall be deemed to have waived notice of such meeting, except where the shareholder objects at the beginning of the meeting to the transaction of business because the time may not lawfully be considered at that meeting and does not participate in the consideration of the item at that meeting.

     Section 2.09. Written Action. Any action which might be taken at a meeting of the shareholders may be taken without a meeting if done in writing and signed by all of the shareholders entitled to vote on that action.

Thereafter, the number of directors shall be established by resolution of the shareholders (subject to the authority of the Board of Directors to increase or decrease the number of directors as permitted by law). In the absence of such shareholder resolution, the number of directors shall be the number last fixed by the shareholders, the Board of Directors, the incorporator or the Articles of Incorporation. Directors need not be shareholders. Each of the directors shall hold office until the regular meeting of shareholders next held after such director’s election and until such director’s successor shall have been elected and shall qualify, or until the earlier death, resignation, removal, or disqualification of such director; provided, however, that no director shall be elected to a term in excess of five years.

     Section 3.03. Board Meetings. Meetings of the Board of Directors may be held from time to time at such time and place within or without the State of Minnesota as may be designated in the notice of such meeting.

     Section 3.04. Calling Meetings; Notice. Meetings of the Board of Directors may be called by the Chairman of the Board by giving at least twenty-four hours’ notice, or by any other director by giving at least five days’ notice, of the date, time and place thereof to each director by mail, telephone, telegram or in person.

     Section 3.05. Waiver of Notice. Notice of any meeting of the Board of Directors may be waived by any director either before, at, or after such meeting orally or in a writing signed by such director. A director, by his attendance at any meeting of the Board of Directors, shall be deemed to have waived notice of such meeting, except where the director objects at the beginning of the meeting to the transaction of business because the meeting is not lawfully called or convened and does not participate thereafter in the meeting.

     Section 3.06. Quorum. A majority of the directors holding office immediately prior to a meeting of the Board of Directors shall constitute a quorum for the transaction of business at such meeting.

     Section 3.07. Absent Directors. A director may give advance written consent or opposition to a proposal to be acted on at a meeting of the Board of Directors. If such director is not present at the meeting, consent or opposition to a proposal does not constitute presence for purposes of determining the existence of a quorum, but consent or opposition shall be counted as a vote in favor of or against the proposal and shall be entered in the minutes or other record of action at the meeting, if the proposal acted on at the meeting is substantially the same or has substantially the same effect as the proposal to which the director has consented or objected.

     Section 3.08. Conference Communications. Any or all directors may participate in any meeting of the Board of Directors, or of any duly constituted committee thereof, by any means of communication through which the directors may simultaneously hear each other during such meeting. For the purposes of establishing a quorum and taking any action at the meeting, such directors participating pursuant to this Section 3.08 shall be deemed present in person at the meeting; and the place of the meeting shall be the place of origination of the conference telephone conversation or other comparable communication technique.

     Section 3.09. Vacancies; Newly Created Directorships. Vacancies in the Board of Directors of this corporation occurring by reason of death, or resignation, removal or disqualification shall be filled for the unexpired term by a majority of the remaining directors of the Board although less than a quorum; newly created directorships resulting from an increase in the authorized number of directors by action of the Board of Directors as permitted by Section 3.02 may be filled by a majority vote of the directors serving at the time of such increase; and each director elected pursuant to this Section 3.09 shall be a director until such director’s successor is elected by the shareholders at their next regular or special meeting.

     Section 3.10. Removal. Any or all of the directors may be removed from office at any time, with or without cause, by the affirmative vote of the shareholders holding a majority of the shares entitled to vote at an election of directors except, as otherwise provided by Minnesota Statutes Section 302A.223, as amended, when the shareholders have the right to cumulate their votes. A director named by the Board of Directors to fill a vacancy may be removed from office at any time, with or without cause, by the affirmative vote of the remaining directors if the shareholders have not elected directors in the interim between the time of the appointment to fill such vacancy and the time of the removal. In the event that the entire Board or any one or more directors be so removed, new directors shall be elected at the same meeting.

     In addition to the foregoing, any director may be removed at any time by the affirmative vote of a majority of the remaining directors if the remaining directors determine that the director to be removed is engaged in an activity that is competitive with any business of the Company. A director may be determined to be engaged in an activity if he or she is an employee, director, partner, consultant, owner, representative, agent or shareholder (other than a shareholder beneficially owning less than 1% of the outstanding stock) of a company, partnership, sole proprietorship or other organization. An activity may be deemed to be competitive with the Company if the product or service created by the activity is the same as or an alternative to any

of the products or services of the Company. The Board of Directors shall determine whether a director is engaged in a competitive activity utilizing the guidelines described in the previous two sentences as well as any other guidelines it determines to be relevant. The Board’s decision shall not be overturned by any court unless the decision is shown to be clearly erroneous.

     Section 3.11. Committees. A resolution approved by the affirmative vote of a majority of the Board of Directors may establish committees having the authority of the board in the management of the business of the corporation to the extent provided in the resolution. A committee shall consist of one or more persons, who need not be directors, appointed by affirmative vote of a majority of the directors present. Committees are subject to the direction and control of, and vacancies in the membership thereof shall be filled by, the Board of Directors, except as provided by Minnesota Statutes Section 302A.243.

     A majority of the members of the committee present at a meeting is a quorum for the transaction of business, unless a larger or small proportion or number is provided in a resolution approved by the affirmative vote of a majority of the directors present.

     Section 3.12. Written Action. Any action which might be taken at a meeting of the Board of Directors, or any duly constituted committee thereof, may be taken without a meeting if done in writing and signed by all of the directors or committee members, unless the Articles provide otherwise and the action need not be approved by the shareholders.

     Section 3.13. Compensation. Directors who are not salaried officers of this corporation shall receive such fixed sum per meeting attended or such fixed annual sum as shall be determined, from time to time, by resolution of the Board of Directors. The Board of Directors may, by resolution, provide that all directors shall receive their expenses, if any, of attendance at meetings of the Board of Directors or any committee thereof. Nothing herein contained shall be construed to preclude any director from serving this corporation in any other capacity and receiving proper compensation therefor.
