The corporation may have such other offices, within or without the state of Minnesota, as the Board of Directors shall, from time to time, determine. SECTION 1.02. CORPORATE SEAL. If so directed by the Board of Directors, the corporation may use a corporate seal.

The seal need only include the word "seal," but it may also include, at the discretion of the Board, such additional wording as is permitted by law. SECTION 1.03. SHAREHOLDER CONTROL AGREEMENT. In the event of any conflict or inconsistency between these Bylaws, or any amendment thereto, and any shareholder control agreement, whenever adopted, such shareholder control agreement shall govern. ARTICLE II MEETINGS OF SHAREHOLDERS SECTION 2.01. TIME AND PLACE OF MEETINGS. Regular or special meetings of the shareholders, if any, shall be held on the date and at the time and place fixed by the President in the absence of Board of Director action, except that a special meeting called by, or at the demand of a shareholder or shareholders, pursuant to Minnesota Statutes, Section 302A.431, Subd. 2, shall be held in the county where the principal executive office is located.

Regular meetings may be held no more frequently than once per year. SECTION 2.03. DEMAND BY SHAREHOLDERS. Regular or special meetings may be demanded by a shareholder or shareholders, pursuant to the provisions of Minnesota Statutes, Section 302A.431, Subd. 2, and 302A.433, Subd. 2, respectively. SECTION 2.03. QUORUM; ADJOURNED MEETINGS. The holders of a majority of the voting power of the shares entitled to vote at a meeting constitute a quorum for the transaction of business; said holders may be present at the meeting either in person or by proxy. If a quorum is present when a duly called or held meeting is convened, the shareholders present may continue to transact business until adjournment, even though withdrawal of shareholders originally present leaves less than the proportion or number otherwise required for a quorum. In case a quorum shall not be present in person or by proxy at a meeting, those present in person or by proxy may adjourn to such day as they shall, by majority vote, agree upon, and a notice of such adjournment shall be mailed to each shareholder entitled to vote at least five (5) days before such adjourned meeting.

At adjourned meetings at which a quorum is present in person or by proxy, any business may be transacted at the meeting as originally noticed. 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.

The Board of Directors may close the books of the corporation against the transfer of shares during the whole or any part of such period. If the Board of Directors fail to fix a record date for determination of the shareholders entitled to notice of, and to vote at, any meeting of shareholders, the record date shall be the fiftieth (50th) day preceding the date of such meeting. SECTION 2.07. NOTICE OF MEETINGS. Notice of all meetings of shareholders shall be given to every holder of voting shares, except where the meeting is an adjourned meeting and the date, time and place of the meeting was announced at the time of adjournment. The notice shall be given at least ten (10) days, but not more than sixty (60) days, before the date of the meeting, except that written notice of a meeting at which an agreement of merger is to be considered shall be given to all shareholders, whether entitled to vote or not, at least fourteen (14) days prior thereto. Every notice of any special meeting shall state the purpose or purposes for which the meeting has been called, and the business transacted at all special meetings shall be confined to the purpose stated in the call, unless all of the shareholders are present in person or by proxy and none of them object to consideration of a particular item of business.
