1.01. Annual Meeting. The annual meeting of the shareholders of the corporation (the “Annual Meeting”) shall be held at such time and date as may be fixed by or under the authority of the Board of Directors, for the purpose of electing directors and for the transaction of such other business as may properly come before the Annual Meeting. If the election of directors shall not be held on the day fixed as herein provided for any Annual Meeting, or at any adjournment thereof, the Board of Directors shall cause the election to be held at a special meeting of the shareholders (a “Special Meeting”) as soon thereafter as conveniently may be. In fixing a meeting date for any Annual Meeting, the Board of Directors may consider such factors as it deems relevant within the good faith exercise of its business judgment.

(a) A Special Meeting may be called only by the Board of Directors pursuant to a resolution adopted by a majority of the entire Board of Directors and shall be called by the Board of Directors upon the demand, in accordance with this Section 1.02, of the holders of record of shares representing at least 10% of all the votes entitled to be cast on any issue proposed to be considered at the Special Meeting.

(b) In order that the corporation may determine the shareholders entitled to demand a Special Meeting, the Board of Directors may fix a record date to determine the shareholders entitled to make such a demand (the “Demand Record Date”). The Demand Record Date shall not precede the date upon which the resolution fixing the Demand Record Date is adopted by the Board of Directors and shall not be more than 10 days after the date upon which the resolution fixing the Demand Record Date is adopted by the Board of Directors. Any shareholder of record seeking to have shareholders demand a Special Meeting shall, by sending written notice to the Secretary of the corporation by hand or by certified or registered mail, return receipt requested, request the Board of Directors to fix a Demand Record Date. The Board of Directors shall promptly, but in all events within 10 days after the date on which a valid request to fix a Demand Record Date is received, adopt a resolution fixing the Demand Record Date and shall make a public announcement of such Demand Record Date. If no Demand Record Date has been fixed by the Board of Directors within 10 days after the date on which such request is received by the Secretary, the Demand Record Date shall be the 10^th day after the first day on which a valid written request to set a Demand Record Date is received by the Secretary. To be valid, such written request shall set forth the purpose or purposes for which the Special Meeting is to be held, shall be signed by one or more shareholders of record (or their duly authorized proxies or

other representatives), shall bear the date of signature of each such shareholder (or proxy or other representative) and shall set forth all information about each such shareholder and about the beneficial owner or owners, if any, on whose behalf the request is made that would be required to be set forth in a shareholder’s notice described in Article IX of the Restated Articles of Incorporation.

(c) In order for a shareholder or shareholders to demand a Special Meeting, a written demand or demands for a Special Meeting by the holders of record as of the Demand Record Date of shares representing at least 10% of all the votes entitled to be cast on any issue proposed to be considered at the Special Meeting must be delivered to the corporation. To be valid, each written demand by a shareholder for a Special Meeting shall set forth the specific purpose or purposes for which the Special Meeting is to be held (which purpose or purposes shall be limited to the purpose or purposes set forth in the written request to set a Demand Record Date received by the corporation pursuant to paragraph (b) of this Section 1.02), shall be signed by one or more persons who as of the Demand Record Date are shareholders of record (or their duly authorized proxies or other representatives), shall bear the date of signature of each such shareholder (or proxy or other representative), and shall set forth the name and address, as they appear in the corporation’s books, of each shareholder signing such demand and the class or series and number of shares of the corporation which are owned of record and beneficially by each such shareholder, shall be sent to the Secretary by hand or by certified or registered mail, return receipt requested, and shall be received by the Secretary within 70 days after the Demand Record Date.

(d) The corporation shall not be required to call a Special Meeting upon shareholder demand unless, in addition to the documents required by paragraph (c) of this Section 1.02, the Secretary receives a written agreement signed by each Soliciting Shareholder (as defined herein), pursuant to which each Soliciting Shareholder, jointly and severally, agrees to pay the corporation’s costs of holding the Special Meeting, including the costs of preparing and mailing proxy materials for the corporation’s own solicitation, provided that if each of the resolutions introduced by any Soliciting Shareholder at such meeting is adopted, and each of the individuals nominated by or on behalf of any Soliciting Shareholder for election as director at such meeting is elected, then the Soliciting Shareholders shall not be required to pay such costs. For purposes of this paragraph (d), the following terms shall have the meanings set forth below.

(i) “Affiliate” shall have the meaning assigned to such term in Rule 12b-2 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

(vi) “Soliciting Shareholder” shall mean, with respect to any Special Meeting demanded by a shareholder or shareholders, any of the following Persons:

(B) if the number of shareholders signing the demand or demands for a meeting delivered to the corporation pursuant to paragraph (c) of this Section 1.02 is more than 10, each Person who either (I) was a Participant in any Solicitation of such demand or demands or (II) at the time of the delivery to the corporation of the documents described in paragraph (c) of this Section 1.02, had engaged or intended to engage in any Solicitation of Proxies for use at such Special Meeting (other than a Solicitation of Proxies on behalf of the corporation); or

(C) any Affiliate of a Soliciting Shareholder, if a majority of the directors then in office determine, reasonably and in good faith, that such Affiliate should be required to sign the written notice described in paragraph (c) of this Section 1.02 and/or the written agreement described in this paragraph (d) in order to prevent the purposes of this Section 1.02 from being evaded.

(e) Except as provided in the following sentence, any Special Meeting shall be held at such hour and day as may be designated by the Board of Directors. In the case of any Special Meeting called by the Board of Directors upon the demand of shareholders (a “Demand Special Meeting”), the date of the Demand Special Meeting shall be not more than 70 days after the Meeting Record Date (as defined in Section 1.05 of these by-laws); provided that in the event that the directors then in office fail to designate an hour and date for a Demand Special Meeting within 10 days after the date that valid written demands for such meeting by the holders of record as of the Demand Record Date of shares representing at least 10% of all the votes entitled to be cast on any issue proposed to be considered at the Special Meeting are delivered to the corporation (the “Delivery Date”), then such meeting shall be held at 2:00 pm. (local time) on the 100^th day after the Delivery Date or, if such 100^th day is not a Business Day (as defined below), on the first preceding Business Day. In fixing a meeting date for any Special Meeting, the Board of Directors may consider such factors as it deems relevant within the good faith exercise of its business judgment, including, without limitation, the nature of the action proposed to be taken, the facts and circumstances surrounding any demand for such meeting, and any plan of the Board of Directors to call an Annual Meeting or a Special Meeting.

(f) The corporation may engage independent inspectors of elections to act as an agent of the corporation for the purpose of promptly performing a ministerial review of the validity of any purported written demand or demands for a Special Meeting received by the Secretary. For the purpose of permitting the inspectors to perform such review, no purported demand shall be deemed to have been delivered to the corporation until the earlier of (i) 5 Business Days following receipt by the Secretary of such purported demand and (ii) such date as the

independent inspectors certify to the corporation that the valid demands received by the Secretary represent at least 10% of all the votes entitled to be cast on each issue proposed to be considered at the Special Meeting. Nothing contained in this paragraph shall in any way be construed to limit the ability of the Board of Directors or any shareholder to contest the validity of any demand, whether during or after such 5 Business Day period, or to take any other action (including, without limitation, the commencement, prosecution or defense of any litigation with respect thereto).

(g) For purposes of these by-laws, “Business Day” shall mean any day other than a Saturday, a Sunday or a day on which banking institutions in the State of Wisconsin are authorized or obligated by law or executive order to close.

The Board of Directors may fix in advance a date not less than 10 days and not more than 70 days prior to the date of any Annual Meeting or Special Meeting as the record date for the determination of shareholders entitled to notice of, or to vote at, such meeting (the “Meeting Record Date”). In the case of any Demand Special Meeting, (i) the Meeting Record Date shall be not later than the 30^th day after the Delivery Date and (ii) if the Board of Directors fails to fix the Meeting Record Date within 30 days after the Delivery Date, then the close of business on such 30^th day shall be the Meeting Record Date.
