When a determination of shareholders entitled to vote at any meeting of shareholders has been made as provided in this section, such determination shall be applied to any adjournment thereof unless the Board of Directors fixes a new record date and except as otherwise required by law. A new record date

- 4 -

must be set if a meeting is adjourned to a date more than 120 days after the date fixed for the original meeting.

2.06 Shareholder List. The officer or agent having charge of the stock transfer books for shares of the corporation shall, before each meeting of shareholders, make a complete record of the shareholders entitled to notice of such meeting, arranged by class or series of shares and showing the address of and the number of shares held by each shareholder. The shareholder list shall be available at the meeting and may be inspected by any shareholder or his or her agent or attorney at any time during the meeting or any adjournment. Any shareholder or his or her agent or attorney may inspect the shareholder list beginning two (2) business days after the notice of the meeting is given and continuing to the date of the meeting, at the corporation’s principal office or at a place identified in the meeting notice in the city where the meeting will be held and, subject to Section 180.1602(2)(b) 3 to 5 of the Wisconsin Business Corporation Law, may copy the list, during regular business hours and at his or her expense, during the period that it is available for inspection hereunder. The original stock transfer books and nominee certificates on file with the corporation (if any) shall be prima facie evidence as to who are the shareholders entitled to inspect the shareholder list or to vote at any meeting of shareholders. Failure to comply with the requirements of this section shall not affect the validity of any action taken at such meeting.

2.07 Quorum and Voting Requirements. Except as otherwise provided in the Articles of Incorporation or in the Wisconsin Business Corporation Law, a majority of the votes entitled to be cast by shares entitled to vote as a separate voting group on a matter, represented in person or by proxy, shall constitute a quorum of that voting group for action on that matter at a meeting of shareholders. If a quorum exists, action on a matter, other than the election of directors, by a voting group is approved if the votes cast within the voting group favoring the action exceed the votes cast opposing the action unless a greater number of affirmative votes is required by the Wisconsin Business Corporation Law or the Articles of Incorporation. If the Articles of Incorporation or the Wisconsin Business Corporation Law provide for voting by two (2) or more voting groups on a matter, action on that matter is taken only when voted upon by each of those voting groups counted separately. Action may be taken by one (1) voting group on a matter even though no action is taken by another voting group entitled to vote on the matter. Once a share is represented for any purpose at a meeting, other than for the purpose of objecting to holding the meeting or transacting business at the meeting, it is considered present for purposes of determining whether a quorum exists for the remainder of the meeting and for any adjournment of that meeting unless a new record date is or must be set for that meeting.

2.08 Conduct of Meetings. The Chairman, or, if there is none, or in his or her absence, the Chief Executive Officer, and in the Chief Executive Officer’s absence, the President, and in the President’s absence, the Chief Operating Officer, and in the Chief Operating Officer’s absence, a Vice President in the order provided under Section 4.07 of these Bylaws, and in their absence, any person chosen by the shareholders present shall call the meeting of the shareholders to order and shall act as chairperson of the meeting, and the Secretary shall act as secretary of all meetings of the shareholders, but, in the absence of the Secretary, the presiding officer may appoint any other person to act as secretary of the meeting.

2.09 Proxies. At all meetings of shareholders, a shareholder entitled to vote may vote in person or by proxy appointed in writing by the shareholder or by his or her duly authorized attorney-in-fact. All proxy appointment forms shall be filed with the Secretary or other officer or agent of the corporation authorized to tabulate votes before or at the time of the meeting. Unless the appointment form conspicuously states that it is irrevocable and the appointment is coupled with an interest, a proxy appointment may be revoked at any time. The presence of a shareholder who has filed a proxy appointment shall not of itself constitute a revocation. No proxy appointment shall be valid after eleven months from the date of its execution, unless otherwise expressly provided in the appointment form. The Board of Directors shall have the power and authority to make rules that are not inconsistent with the Wisconsin Business Corporation Law as to the validity and sufficiency of proxy appointments.

2.10 Voting of Shares. Each outstanding share shall be entitled to one (1) vote on each matter submitted to a vote at a meeting of shareholders, except to the extent that the voting rights of the shares are enlarged, limited or denied by the Articles of Incorporation or the Wisconsin Business Corporation Law. Shares owned directly or indirectly by another corporation are not entitled to vote if this corporation owns, directly or indirectly, sufficient shares to elect a majority of the directors of such other corporation. However, the prior sentence shall not limit the power of the corporation to vote any shares, including its own shares, held by it in a fiduciary capacity. Redeemable shares are not entitled to vote after notice of redemption is mailed to the holders and a sum sufficient to redeem the shares has been deposited with a bank, trust company, or other financial institution under an irrevocable obligation to pay the holders the redemption price on surrender of the shares.

The removal may be made with or without cause unless the Articles of Incorporation or these Bylaws provide that directors may be removed only for cause. If a director is elected by a voting group of shareholders, only the shareholders of that voting group may participate in the vote to remove that director.

If the vacant office was held by a director elected by a voting group of shareholders, only the holders of shares of that voting group may vote to fill the vacancy if it is

- 10 -

filled by the shareholders, and only the remaining directors elected by that voting group may vote to fill the vacancy if it is filled by the directors. A vacancy that will occur at a specific later date (because of a resignation effective at a later date or otherwise) may be filled before the vacancy occurs, but the new director may not take office until the vacancy occurs.

3.13 Committees. Unless the Articles of Incorporation otherwise provide, the Board of Directors, by resolution adopted by the affirmative vote of a majority of all the directors then in office, may create one (1) or more committees, each committee to consist of two (2) or more directors as members, which to the extent provided in the resolution as initially adopted, and as thereafter supplemented or amended by further resolution adopted by a like vote, may exercise the authority of the Board of Directors, except that no committee may: (a) authorize distributions; (b) approve or propose to shareholders action that the Wisconsin Business Corporation Law requires be approved by shareholders; (c) fill vacancies on the Board of Directors or any of its committees, except that the Board of Directors may provide by resolution that any vacancies on a committee shall be filled by the affirmative vote of a majority of the remaining committee members; (d) amend the Articles of Incorporation; (e) adopt, amend or repeal Bylaws; (f) approve a plan of merger not requiring shareholder approval; (g) authorize or approve reacquisition of shares, except according to a formula or method prescribed by the Board of Directors or (h) authorize or approve the issuance or sale or contract for sale of shares, or determine the designation and relative rights, preferences and limitations of a class or series of shares, except within limits prescribed by the Board of Directors. The Board of Directors may elect one or more of its members as alternate members of any such committee who may take the place of any absent member or members at any meeting of such committee, upon request by the Chairman, the Chief Executive Officer, the President or upon request by the chairperson of such meeting. Each such committee shall fix its own rules (consistent with the Wisconsin Business Corporation Law, the Articles of Incorporation and these Bylaws) governing the conduct of its activities and shall make such reports to the Board of Directors of its activities as the Board of Directors may request. Unless otherwise provided by the Board of Directors in creating a committee, a committee may employ counsel, accountants and other consultants to assist it in the exercise of authority. The creation of a committee, delegation of authority to a committee or action by a committee does not relieve the Board of Directors or any of its members of any responsibility imposed on the Board of Directors or its members by law.

ARTICLE V. SHARES AND THEIR TRANSFER

5.01 Certificates for Shares; Uncertificated Shares. Shares of the corporation’s stock may be certificated or uncertificated, as provided under the Wisconsin Business Corporation Law.

(a) Shares of this corporation may be represented by certificates. Certificates representing shares of the corporation shall be in such form, consistent with law, as shall be determined by the Board of Directors. At a minimum, a share certificate shall state on its face the name of the corporation and that it is organized under the laws of the State of Wisconsin, the name of the person to whom issued, and the number and class of shares and the designation of the series, if any, that the certificate represents. If the corporation is authorized to issue different classes of shares or different series within a class, the front or back of the certificate must contain either (i) a summary of the designations, relative rights, preferences and limitations applicable to each class, and the variations in the rights, preferences and limitations determined for each series and the authority of the Board of Directors to determine variations for future series, or (ii) a conspicuous statement that the corporation will furnish the shareholder the information described in clause (i) on request, in writing and without charge. Such certificates shall be signed, either manually or in facsimile, by the Chairman, the Chief Executive Officer, the President, the Chief Operating Officer, or a Vice President and by the Secretary or an Assistant Secretary. All certificates for shares shall be consecutively numbered or otherwise identified. The name and address of the person to whom the shares represented thereby are issued, with the number of shares and date of issue, shall be entered on the stock transfer books of the corporation. All certificates surrendered to the corporation for transfer shall be cancelled and no new certificate or uncertificated shares shall be issued until, in the case of shares represented by a stock certificate, the former certificate for a like number of shares shall have been surrendered and cancelled, except as provided in Section 5.05.

(b) The Board of Directors may authorize the issuance of some or all of any or all classes or series of the corporation’s stock, common, preferred or otherwise, without certificates. The authorization does not affect shares already represented by certificates until the certificates are surrendered to the corporation. Within a reasonable time after the issuance or transfer of shares without certificates, the corporation shall send the shareholder a written

- 15 -

statement of the information required on share certificates by paragraph (a) of this Section 5.01 and, if applicable, Section 5.04. Unless the Wisconsin Business Corporation Law or Chapter 408 of the Wisconsin Statutes expressly provides otherwise, the rights and obligations of shareholders are identical whether or not their shares are represented by certificates.

5.02 Signature by Former Officers. If an officer or assistant officer, who has signed or whose facsimile signature has been placed upon any certificate for shares, has ceased to be such officer or assistant officer before such certificate is issued, the certificate may be issued by the corporation with the same effect as if that person were still an officer or assistant officer at the date of its issue.

5.03 Transfer of Shares. The corporation’s books shall reflect transfers of shares only if a transfer of such shares has been made or directed by the record holder of such shares, or by attorney lawfully constituted in writing, and, in the case of shares represented by a certificate, upon surrender of the certificate. Prior to due presentment of a certificate for shares for registration of transfer, and unless the corporation has established a procedure by which a beneficial owner of shares held by a nominee is to be recognized by the corporation as the shareholder, the corporation may treat the registered owner of such shares as the person exclusively entitled to vote, to receive notifications and otherwise to have and exercise all the rights and power of an owner. The corporation may require reasonable assurance that all transfer endorsements are genuine and effective and in compliance with all regulations prescribed by or under the authority of the Board of Directors.

5.04 Restrictions on Transfer. The face or reverse side of each certificate representing shares, and the written statement of the information required by Section 5.01(b) with respect to shares without certificates, shall bear a conspicuous notation of any restriction upon the transfer of such shares imposed by the corporation or imposed by any agreement of which the corporation has written notice.

5.05 Lost, Destroyed or Stolen Certificates. Where the owner claims that his or her certificate for shares has been lost, destroyed or wrongfully taken, a new certificate or shares in uncertificated form shall be issued in place thereof if the owner (a) so requests before the corporation has notice that such shares have been acquired by a bona fide purchaser, and (b) if required by the corporation, files with the corporation a sufficient indemnity bond, and (c) satisfies such other reasonable requirements as may be prescribed by or under the authority of the Board of Directors.

5.06 Consideration for Shares. The shares of the corporation may be issued for such consideration as shall be fixed from time to time and determined to be adequate by the Board of Directors, provided that any shares having a par value shall not be issued for a consideration less than the par value thereof. The consideration may consist of any tangible or intangible property or benefit to the corporation, including cash, promissory notes, services performed, contracts for services to be performed, or other securities of the corporation. When the corporation receives the consideration for which the Board of Directors authorized the issuance of shares, such shares shall be deemed to be fully paid and nonassessable by the corporation.

- 16 -

5.07 Stock Regulations. The Board of Directors shall have the power and authority to make all such rules and regulations not inconsistent with the statutes of the State of Wisconsin as it may deem expedient concerning the issue, transfer and registration of shares of the corporation, including the appointment or designation of one or more stock transfer agents and one or more registrars.

ARTICLE VI. WAIVER OF NOTICE

6.01 Shareholder Written Waiver. A shareholder may waive any notice required by the Wisconsin Business Corporation Law, the Articles of Incorporation or these Bylaws before or after the date and time stated in the notice. The waiver shall be in writing and signed by the shareholder entitled to the notice, shall contain the same information that would have been required in the notice under the Wisconsin Business Corporation Law except that the time and place of meeting need not be stated, and shall be delivered to the corporation for inclusion in the corporate records.

6.02 Shareholder Waiver by Attendance. A shareholder’s attendance at a meeting, in person or by proxy, waives objection to both of the following:

(a) Lack of notice or defective notice of the meeting, unless the shareholder at the beginning of the meeting or promptly upon arrival objects to holding the meeting or transacting business at the meeting.

(b) Consideration of a particular matter at the meeting that is not within the purpose described in the meeting notice, unless the shareholder objects to considering the matter when it is presented.

The waiver shall be in writing, signed by the director entitled to the notice and retained by the corporation.

6.04 Director Waiver by Attendance. A director’s attendance at or participation in a meeting of the Board of Directors or any committee thereof waives any required notice to him or her of the meeting unless the director at the beginning of the meeting or promptly upon his or her arrival objects to holding the meeting or transacting business at the meeting and does not thereafter vote for or assent to action taken at the meeting.

ARTICLE VII. ACTION WITHOUT MEETINGS

7.01 Shareholder Action Without Meeting. Action required or permitted by the Wisconsin Business Corporation Law to be taken at a shareholders’ meeting may be taken without a meeting by all shareholders entitled to vote on the action. The action must be evidenced by one or more written consents describing the action taken, signed by the shareholders consenting thereto and delivered to the corporation for inclusion in its corporate records. A consent hereunder has the effect of a meeting vote and may be described as such in any document. The Wisconsin Business Corporation Law requires that notice of the action be

- 17 -

given to certain shareholders and specifies the effective date thereof and the record date in respect thereto.

7.02 Director Action Without Meeting. Unless the Articles of Incorporation provide otherwise, action required or permitted by the Wisconsin Business Corporation Law to be taken at a Board of Directors meeting or committee meeting may be taken without a meeting if the action is taken by all members of the Board or committee. The action shall be evidenced by one or more written consents describing the action taken, signed by each director and retained by the corporation. Action taken hereunder is effective when the last director signs the consent, unless the consent specifies a different effective date. A consent signed hereunder has the effect of a unanimous vote taken at a meeting at which all directors or committee members were present, and may be described as such in any document.

8.01 Indemnification for Successful Defense. Within twenty (20) days after receipt of a written request pursuant to Section 8.03, the corporation shall indemnify a director or officer, to the extent he or she has been successful on the merits or otherwise in the defense of a proceeding, for all reasonable expenses incurred in the proceeding if the director or officer was a party because he or she is a director or officer of the corporation.

8.02 Other Indemnification.

(a) In cases not included under Section 8.01, the corporation shall indemnify a director or officer against all liabilities and expenses incurred by the director or officer in a proceeding to which the director or officer was a party because he or she is a director or officer of the corporation, unless liability was incurred because the director or officer breached or failed to perform a duty he or she owes to the corporation and the breach or failure to perform constitutes any of the following:

(1) A willful failure to deal fairly with the corporation or its shareholders in connection with a matter in which the director or officer has a material conflict of interest.

- 18 -

8.03 Written Request. A director or officer who seeks indemnification under Sections 8.01 or 8.02 shall make a written request to the corporation.

8.04 Nonduplication.

8.05 Determination of Right to Indemnification.

(a) Unless otherwise provided by the Articles of Incorporation or by written agreement between the director or officer and the corporation, the director or officer seeking indemnification under Section 8.02 shall select one of the following means for determining his or her right to indemnification:

If a quorum of disinterested directors cannot be obtained, by majority vote of a committee duly appointed by the Board of Directors and consisting solely of two (2) or more directors who are not at the time parties to the same or related proceedings. Directors who are parties to the same or related proceedings may participate in the designation of members of the committee.

(2) By independent legal counsel selected by a quorum of the Board of Directors or its committee in the manner prescribed in subsection (1) or, if unable to obtain such a quorum or committee, by a majority vote of the full Board of Directors, including directors who are parties to the same or related proceedings.

(3) By a panel of three (3) arbitrators consisting of one arbitrator selected by those directors entitled under subsection (2) to select independent legal counsel, one arbitrator selected by the director or officer seeking indemnification and one arbitrator selected by the two (2) arbitrators previously selected.

(4) By an affirmative vote of shares represented at a meeting of shareholders at which a quorum of the voting group entitled to vote thereon is present.

- 19 -

(5) By a court under Section 8.08.

(6) By any other method provided for in any additional right to indemnification permitted under Section 8.07.

(b) In any determination under (a), the burden of proof is on the corporation to prove by clear and convincing evidence that indemnification under Section 8.02 should not be allowed.

(b) A written undertaking, executed personally or on his or her behalf, to repay the allowance to the extent that it is ultimately determined under Section 8.05 that indemnification under Section 8.02 is not required and that indemnification is not ordered by a court under Section 8.08(b)(2). The undertaking under this subsection shall be an unlimited general obligation of the director or officer and may be accepted without reference to his or her ability to repay the allowance. The undertaking may be secured or unsecured.

8.07 Nonexclusivity.

(a) Except as provided in (b), Sections 8.01, 8.02 and 8.06 do not preclude any additional right to indemnification or allowance of expenses that a director or officer may have under any of the following:

A director or officer who is a party to the same or related proceeding for which indemnification or an allowance of expenses is sought may not participate in a determination under this subsection.

ARTICLE X. AMENDMENTS

10.01 By Shareholders. These Bylaws may be amended or repealed and new Bylaws may be adopted by the shareholders by the vote provided in Section 2.07 of these Bylaws or as specifically provided below. If authorized by the Articles of Incorporation, the shareholders may adopt or amend a Bylaw that fixes a greater or lower quorum requirement or a greater voting requirement for shareholders or voting groups of shareholders than otherwise is provided in the Wisconsin Business Corporation Law. The adoption or amendment of a Bylaw that adds, changes or deletes a greater or lower quorum requirement or a greater voting requirement for shareholders must meet the same quorum requirement and be adopted by the same vote and voting groups required to take action under the quorum and voting requirement then in effect.

10.02 By Directors. Except as the Articles of Incorporation may otherwise provide, these Bylaws may also be amended or repealed and new Bylaws may be adopted by the Board of Directors by the vote provided in Section 3.08, but (a) no Bylaw adopted by the shareholders shall be amended, repealed or readopted by the Board of Directors if the Bylaw so adopted so provides and (b) a Bylaw adopted or amended by the shareholders that fixes a greater or lower quorum requirement or a greater voting requirement for the Board of Directors than otherwise is provided in the Wisconsin Business Corporation Law may not be amended or repealed by the Board of Directors unless the Bylaw expressly provides that it may be amended or repealed by a specified vote of the Board of Directors. Action by the Board of Directors to adopt or amend a Bylaw that changes the quorum or voting requirement for the Board of Directors must meet the same quorum requirement and be adopted by the same vote required to take action under the quorum and voting requirement then in effect, unless a different voting requirement is specified as provided by the preceding sentence. A Bylaw that fixes a greater or lower quorum requirement or a greater voting requirement for shareholders or voting groups of shareholders than otherwise is provided in the Wisconsin Business Corporation Law may not be adopted, amended or repealed by the Board of Directors.

10.03 Implied Amendments. Any action taken or authorized by the shareholders or by the Board of Directors, which would be inconsistent with the Bylaws then in effect but is taken or authorized by a vote that would be sufficient to amend the Bylaws so that the Bylaws would be consistent with such action, shall be given the same effect as though the Bylaws had been temporarily amended or suspended so far, but only so far, as is necessary to permit the specific action so taken or authorized.
