<P style="margin-top:0px; margin-bottom:13.333px; text-indent:48px">Unless otherwise provided in a corporation&#146;s articles of incorporation or by-laws, or by written agreement, the director or officer seeking indemnification is entitled to select one of the following means for determining his or her right to indemnification: &nbsp;(i) by majority vote of a disinterested quorum of the board of directors, or if such quorum of disinterested directors cannot be obtained, by a majority vote of a committee duly appointed by the board of directors of two or more disinterested directors; (ii) by independent legal counsel; (iii) by a panel of three arbitrators; (iv) by affirmative vote of shareholders; (v) by a court; or (vi) with respect to any additional right to indemnification, by any other method permitted in Section 180.0858 of the WBCL. </P>
<P style="margin-top:0px; margin-bottom:13.333px; text-indent:48px">Reasonable expenses incurred by a director or officer who is a party to a proceeding may be paid or reimbursed by a corporation at such time as the director or officer furnishes to the corporation a written affirmation of his or her good faith belief that he or she has not breached or failed to perform his or her duties to the corporation and a written undertaking to repay any amounts advanced if it is determined that indemnification by the corporation is not required. </P>
<P style="margin-top:0px; margin-bottom:13.333px; text-indent:48px">The indemnification provisions of Section 180.0850 to 180.0859 of the WBCL are not exclusive. &nbsp;A corporation may expand a director&#146;s or officer&#146;s rights to indemnification: &nbsp;(i) in its articles of incorporation or by-laws; (ii) by written agreement; (iii) by resolution of its board of directors; or (iv) by resolution that is adopted, after notice, by a majority of all of the corporation&#146;s voting shares then issued and outstanding.</P>
<P style="margin-top:0px; margin-bottom:13.333px; text-indent:48px">As permitted by Section 180.0858 of the WBCL, the Registrant has adopted indemnification provisions in its bylaws that closely track the statutory indemnification provisions of the WBCL with certain exceptions. &nbsp;In particular, Article XI of the Registrant&#146;s bylaws, among other items, provides that (i) an individual shall be indemnified unless it is proven by a final judicial adjudication that indemnification is prohibited and (ii) payment or reimbursement of expenses, subject to certain limitations, will be mandatory rather than permissive. &nbsp;In addition, all officers, directors, employees, and agents of controlled subsidiaries of the Registrant shall be deemed for purposes of Article XI to be serving as such officers, directors, employees, and agents at the request of the Registrant. The right to indemnification granted to such officers, directors, employees and agents by Article XI is not subject to any limitation or restriction imposed by any provision of the articles of incorporation or bylaws of such controlled subsidiary; provided, however, that any right to indemnification so granted shall be subject to and limited by the laws and regulations of any applicable regulatory authority to which such controlled subsidiary is subject. For purposes of Article XI, a &#147;controlled subsidiary&#148; means any corporation at least 80% of the outstanding voting stock of which is owned by the Registrant or another controlled subsidiary of the Registrant.</P>
<P style="margin-top:0px; margin-bottom:13.333px; text-indent:48px">As permitted by Section 180.0857 of the WBCL, the Registrant has purchased directors&#146; and officers&#146; liability insurance that insures the Registrant&#146;s directors and officers, among other things, against certain liabilities that may arise under the Securities Act. &nbsp;</P>

Item 6.
Indemnification of Directors and Officers
Sections 180.0850 to 180.0859 of the Wisconsin Business Corporation Law (the "WBCL") require a corporation to indemnify a director or officer, to the extent that he or she has been successful on the merits or otherwise in the defense of a proceeding, which includes any threatened, pending or completed civil, criminal, administrative or investigative action, suit, arbitration or other proceeding, whether formal or informal, which involves foreign, federal, state or local law and which is brought by or in the right of the corporation or by any other
3
person, 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.  A corporation is obligated to indemnify a director or officer against liability 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, which liability includes the obligation to pay a judgment, settlement, penalty, assessment, forfeiture or fine, including any excise tax assessed with respect to an employee benefit plan, and all reasonable expenses including fees, costs, charges, disbursements, attorney fees and other expenses, unless such liability was incurred as a result of the breach or failure to perform a duty which the director or officer owes to the corporation and the breach or failure to perform constitutes:  (i) 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; (ii) a violation of criminal law, unless the director or officer had reasonable cause to believe that his or her conduct was lawful or no reasonable cause to believe that his or her conduct was unlawful; (iii) a transaction from which the director or officer derived an improper personal profit; or (iv) willful misconduct.
Unless otherwise provided in a corporation's articles of incorporation or by-laws, or by written agreement, the director or officer seeking indemnification is entitled to select one of the following means for determining his or her right to indemnification:  (i) by majority vote of a disinterested quorum of the board of directors, or if such quorum of disinterested directors cannot be obtained, by a majority vote of a committee duly appointed by the board of directors of two or more disinterested directors; (ii) by independent legal counsel; (iii) by a panel of three arbitrators; (iv) by affirmative vote of shareholders; (v) by a court; or (vi) with respect to any additional right to indemnification, by any other method permitted in Section 180.0858 of the WBCL.
Reasonable expenses incurred by a director or officer who is a party to a proceeding may be paid or reimbursed by a corporation at such time as the director or officer furnishes to the corporation a written affirmation of his or her good faith belief that he or she has not breached or failed to perform his or her duties to the corporation and a written undertaking to repay any amounts advanced if it is determined that indemnification by the corporation is not required.
The indemnification provisions of Section 180.0850 to 180.0859 of the WBCL are not exclusive.  A corporation may expand a director's or officer's rights to indemnification:  (i) in its articles of incorporation or by-laws; (ii) by written agreement; (iii) by resolution of its board of directors; or (iv) by resolution that is adopted, after notice, by a majority of all of the corporation's voting shares then issued and outstanding.
As permitted by Section 180.0858 of the WBCL, the Registrant has adopted indemnification provisions in its bylaws that closely track the statutory indemnification provisions of the WBCL with certain exceptions.  In particular, Article XI of the Registrant's bylaws, among other items, provides that (i) an individual shall be indemnified unless it is proven by a final judicial adjudication that indemnification is prohibited and (ii) payment or reimbursement of expenses, subject to certain limitations, will be mandatory rather than permissive.  In addition, all officers, directors, employees, and agents of controlled subsidiaries of the Registrant shall be deemed for purposes of Article XI to be serving as such officers, directors, employees, and agents at the request of the Registrant. The right to indemnification granted to such officers, directors, employees and agents by Article XI is not subject to any limitation or restriction imposed by any provision of the articles of incorporation or bylaws of such controlled subsidiary; provided, however, that any right to indemnification so granted shall be subject to and limited by the laws and regulations of any applicable regulatory authority to which such controlled subsidiary is subject. For purposes of Article XI, a "controlled subsidiary" means any corporation at least 80% of the outstanding voting stock of which is owned by the Registrant or another controlled subsidiary of the Registrant.
As permitted by Section 180.0857 of the WBCL, the Registrant has purchased directors' and officers' liability insurance that insures the Registrant's directors and officers, among other things, against certain liabilities that may arise under the Securities Act.

The Registrant hereby undertakes that is has submitted or will submit the 401(k) Plan and any amendments thereto to the Internal Revenue Service in order to qualify the 401(k) Plan and has made or will make all changes required by the Internal Revenue Service to qualify the 401(k) Plan.
Item 9.
Undertakings
*
The undersigned Registrant hereby undertakes:
(a)
(1)
To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
(i)
to include any prospectus required by section 10(a)(3) of the Securities Act;
(ii)
to reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement.  Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement;
(iii)
to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;
Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the SEC by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.
(2)
That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering.
(b)
That, for the purpose of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, each
5
filing of the Plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(h)
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described in Item 6 of this Registration Statement, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
