INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

        2.       The description of the Company’s Common Stock contained in Item 1 of the Company’s Registration Statement on Form 8-A, dated July 25, 1991, filed with the Commission pursuant to Section 12 of the Securities Exchange Act of 1933, as amended, and any amendments or reports filed for the purpose of updating such description.

Item 6.   Indemnification of Directors and Officers.

        Pursuant to the Wisconsin Business Corporation Law and the Company’s by-laws, directors and officers of the Company are entitled to mandatory indemnification from the Company against certain liabilities and expenses (i) to the extent such officers or directors are successful in the defense of a proceeding and (ii) in proceedings in which the director or officer is not successful in the defense thereof unless it is determined that the director or officer breached or failed to perform his or her duties to the Company and such breach or failure constituted: (a) a willful failure to deal fairly with the Company or its shareowners in connection with a matter in which the director or officer had a material conflict of interest; (b) a violation of the criminal law, unless the director or officer had reasonable cause to believe his or her conduct was lawful or had no reasonable cause to believe his or her conduct was unlawful; (c) a transaction from which the director or officer derived an improper personal profit; or (d) willful misconduct. The Wisconsin Business Corporation Law specifically states that it is the policy of Wisconsin to require or permit indemnification in connection with a proceeding involving securities regulation, as described therein, to the extent required or permitted as described above. Additionally, under the Wisconsin Business Corporation Law, directors of the Company are not subject to personal liability to the Company, its shareowners or any person asserting rights on behalf thereof for certain breaches or failures to perform any duty resulting solely from their status as directors except in circumstances paralleling those in subparagraphs (a) through (d) outlined above.

        The indemnification provided by the Wisconsin Business Corporation Law and the Company’s by-laws is not exclusive of any other rights to which a director or officer may be entitled. The general effect of the foregoing provisions may be to reduce the circumstances under which an officer or director may be required to bear the economic burden of the foregoing liabilities and expenses.

        The Company maintains a liability insurance policy for its directors and officers as permitted by Wisconsin law which may extend to, among other things, liability arising under the Securities Act of 1933, as amended.

Item 7.   Exemption from Registration Claimed.

        Not applicable.

Item 8.   Exhibits.

        The exhibits filed herewith or incorporated herein by reference are set forth in the attached Exhibit Index.

Item 9.   Undertakings.

(a) The undersigned registrant hereby undertakes:

  (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 of 1933;






3



  (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; and

  (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 by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

  (2) That, for the purpose of determining any liability under the Securities Act of 1933, 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 which remain unsold at the termination of the offering.

(b) Filings Incorporating Subsequent Exchange Act Documents by Reference.

  The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 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

(c) Statement Required in Connection with Filing of Registration Statement on Form S-8.

  Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of such issue.
