Participation by remote communication constitutes presence at the meeting.

At such meeting, directors shall be elected to succeed those whose terms are expiring and to fill any other vacancies, reports of the affairs of the Corporation shall be considered, and other business may be transacted.

If the meeting is to be held by remote communication, the notice shall state the means of remote communication by which shareholders will be deemed present and entitled to vote at the meeting.

SECTION 5. QUORUM; ADJOURNED MEETINGS. The presence in person or by proxy of the holders of a majority of the voting power of the shares entitled to vote at any meeting shall constitute an quorum for the transaction of business. A meeting may be adjourned from time to time, whether or not a quorum is present. If any meeting is adjourned, no further notice as to such adjourned meeting need be given other than by announcement at the time of adjournment of the date, time and place of the adjourned 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 when a meeting is convened, the shareholders present may continue to transact business until adjournment notwithstanding the withdrawal of enough shareholders originally present to leave less than a quorum.

SECTION 6. VOTING.

ARTICLE III - DIRECTORS

SECTION 1. NUMBER. In addition to any director who may be elected by the holders of any one or more series of Preferred Stock voting separately as such (the “Series Directors”), the Board of Directors shall consist of a number of directors, which number shall be fixed from time to time exclusively by the Board of Directors pursuant to a resolution adopted by the affirmative vote of a majority of the entire Board of Directors, but the number of directors shall in no event be more than fifteen (excluding any Series Directors).

SECTION 2. TERM OF OFFICE VACANCIES AND REMOVAL.

(a) The directors to be elected by the holders of the shares of Common Stock and of any other shares of capital stock entitled to vote as a single class with the shares of Common Stock shall be divided into three classes designated Class I, Class II and Class III. The term of one class of directors shall expire each year. Each class shall consist, as nearly as may be possible, of one-third of the total number of directors fixed pursuant to Section 1 of this Article III. At each Annual Meeting of Shareholders, the directors elected to succeed those directors whose terms expire shall be elected for a term expiring three years after the date of their election and until their successors are duly elected and qualified.

(b) If the number of directors is changed, any increase or decrease shall be apportioned among the three classes so as to maintain the number of directors in each class as nearly equal as possible, and any additional director of any class elected to fill a vacancy resulting from an increase in such class shall hold office for a term that shall coincide with the remaining term of that class but in no case shall a decrease in the number of directors shorten the term of any incumbent director. Subject to the rights of the holders of any class or series of the then outstanding capital stock of the Corporation entitled to vote generally in the election of directors (other than Series Directors), newly created directorships resulting from any increase in the authorized number of directors or any vacancies in any class resulting from death, resignation, retirement, disqualification, removal from office or other cause may be filled only by a majority vote of the directors (other than Series Directors) then in office, although less than a quorum. Directors so elected shall hold office for a term expiring at the time at which the term of office of the class to which they have been elected expires and until their successors are duly elected and qualified.

(c) Any directors, or the entire Board of Directors, may be removed from office at any time for good cause by the affirmative vote of the holders of at least two-thirds of the combined voting power of the shares of the classes or series of capital stock of the Corporation present and voting as a single class. A director named by the Board of Directors to

6

fill a vacancy may be removed from office at any time, with our without cause, by the affirmative vote of a majority 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 removal. In the event that any one or more directors or the entire Board is removed at a shareholder’s meeting, a new director or new directors shall be elected at the same meeting.

(d) Notwithstanding the provisions of Article VI of these Bylaws, any amendment, alteration, change or repeal of Sections 1 and/or 2 of Article III of these Bylaws shall require the affirmative vote of the holders of two-thirds of the shares present and voting as a single class.

SECTION 3. NOMINATION OF DIRECTORS. Only persons nominated in accordance with the following procedures shall be eligible for election by shareholders as directors, except as may otherwise be provided in the Articles of Incorporation of the Corporation with respect to the right of holders of a series of preferred stock of the Corporation to nominate and elect a specified number of directors. To be properly brought before an annual meeting of the shareholders, or any special meeting of the shareholders called for the purpose of electing directors, nominations for the election of a director must be:

In addition to any other applicable requirements, for a nomination to be made by a shareholder, such shareholder must have given timely notice thereof in proper written form to the Secretary of the Corporation. In the case of an annual meeting, to be timely, a shareholder’s notice to the Secretary must be delivered to or mailed and received at the Corporation’s principal executive offices not later than the close of business on the 90^th day, nor earlier than the close of business on the 120^th day, prior to the anniversary date of the immediately preceding annual meeting; provided, however, that in the event that no annual meeting was held in the previous year or the annual meeting is called for a date that is not within 30 days before or after such anniversary date, notice by the shareholder to be timely must be so received not later than the close of business on the 10^th day following the day on which such notice of the date of the meeting was mailed or public disclosure of the date of the meeting was made, whichever occurs first. In the case of a special meeting of the shareholders called for the purpose of electing directors, to be timely, a shareholder’s notice to the Secretary must be delivered to or mailed and received at the Corporation’s executive offices not later than the close of business on the 10^th day following the day on which notice of the date of the special meeting was mailed or public disclosure of the date of the special meeting was made, whichever first occurs.

Subject to the rights of any holders of a series of preferred stock of the Corporation, no person shall be eligible for election as a director of the Corporation unless nominated in accordance with the procedures set forth in this Section 3. If the chair of the meeting properly determines that a nomination was not made in accordance with the foregoing procedures, the chair shall declare to the meeting that the nomination was defective and such defective nomination shall be disregarded.

SECTION 4. MEETINGS. The Board of Directors may provide by resolution the date, time and place, either within or without the State of Minnesota, for the holding of meetings of the Board of Directors without other notice than such resolution.

Other meetings of the Board of Directors may be called by the Chair of the Board, the Vice Chair of the Board, the Chief Executive Officer (if a director) or any two other directors. The person or persons authorized to call meetings of the Board of Directors may fix any place, either within or without the State of Minnesota, as the place for holding any meeting of the Board of Directors called by them. In the absence of such designation, all called meetings of the Board of Directors shall be held at the principal executive office of the Corporation.

The Board of Directors shall choose from among the directors a Chair of the Board and may from time to time choose a Vice Chair of the Board.

Notice of any called meeting of the Board of Directors shall be given by the person or persons calling the meeting (or by the Secretary or an Assistant Secretary at the request of such person or persons) either by mail to each director at the director’s business address at least two days prior to such meeting or by telegram, telecopy, facsimile, telephone, or in person at least 24 hours prior to such meeting to the business address of each director, or in the event such notice is given on a Saturday, Sunday or holiday to the residence address of each director. If the day or date, time and place of a meeting of the Board of Directors has been announced at a previous meeting of the Board of Directors, no notice is required. Notice of an adjourned meeting of the Board of Directors need not be given other than by announcement at the meeting at which adjournment is taken.

Neither the business to be transacted at, nor the purpose of, any regular or called meeting of the Board of Directors needs to be specified in the notice of such meeting.

9

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 or her 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.

The members of the Board of Directors, the Executive Committee or any other committee created by the Board of Directors may participate in a meeting of the Board of Directors or such Committee by any means of communication through which the directors may simultaneously hear each other during the meeting and such participation in a meeting shall constitute presence in person at such meeting.

Any action which may be taken at a meeting of the Board of Directors, the Executive Committee or any other committee of the Board of Directors may be taken without a meeting if a consent in writing, setting forth the action so taken, shall be signed by all of the directors or committee members then holding office.

SECTION 5. QUORUM; REQUIRED VOTE. A majority of the directors then holding office shall constitute a quorum for the transaction of business by the Board of Directors. The Board of Directors shall take action by the affirmative vote of the greater of (a) majority of the directors present at a duly held meeting at the time the action is taken, or (b) a majority of the minimum number of directors that would constitute a quorum for the transaction of business at the meeting. A majority of the members of any committee appointed by the Board of Directors and then holding office shall constitute a quorum for the transaction of business by such committee. Any committee shall take action by the affirmative vote of the greater of (a) majority of the members present at a duly held meeting at the time the action is taken, (b) a majority of the minimum number of members that would constitute a quorum for the transaction of business at the meeting, or (c) such higher requirement as may be established by the Board of Directors. Notwithstanding the foregoing, where other sections of these Bylaws or the Articles of Incorporation of the Corporation require a larger proportion or number than is set forth in this Section 5 of Article III, the affirmative vote of such larger proportion or number shall be required for the Board of Directors or a committee of the Board of Directors to take action.

SECTION 6. EXECUTIVE COMMITTEE. By the affirmative action of at least three fourths of the directors then holding office, the Board of Directors by resolution may create an Executive Committee of three or more directors and may delegate to such committee such of its powers and authority in the management of the business and affairs of the Corporation as it may by resolution provide, except the power to declare dividends and to adopt, amend or repeal the Bylaws.

SECTION 7. OTHER COMMITTEES. The Board of Directors by resolution may create, in addition to an Executive Committee, ad hoc and standing committees, and may

10

delegate to such Committees such of its powers as it may choose, including without limitation the power to perform such inquiries, investigations or analyses as may be required from time to time, and to report the results of any of their findings and their recommendations to the Board of Directors for such action as the Board of Directors deems to be appropriate.

SECTION 8. COMPENSATION. The directors, by resolution of the Board of Directors, may be paid fees and provided benefits and may be reimbursed for expenses incurred by them on behalf of the Corporation, which fees, benefits and expenses shall be paid at such times and upon such conditions as may be determined by the Board of Directors; provided, however, that the shareholders at any meeting called for the purpose may revoke or rescind any such action by the Board of Directors, but may not revoke or rescind any action of the Board of Directors (i) authorizing reimbursement to directors for expenses incurred by them on behalf of the Corporation or (ii) establishing vested or contractual compensation or benefit arrangements for directors. Nothing herein contained shall be construed to preclude any director from serving the Corporation in any other capacity as an officer, agent, employee, or otherwise, and receiving compensation therefor.

SECTION 9. EMERITUS DIRECTORS. The Board of Directors may from time to time appoint a former director to the honorary position of “Director Emeritus” or, in the case of a former Chair of the Board (whether or not then also a director), “Chair Emeritus.” A former director holding an honorary position may be invited to attend meetings or portions of meetings of the Board of Directors, but shall have no voting or other rights of a director and shall not be entitled to the compensation payable to directors.
