 ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Registrant is incorporated under the Wisconsin Business Corporation
 Law and pursuant to sections 180.0850 to 180.0859 of the Wisconsin
 statutes, subject to the limitations stated therein, is required to
 indemnify any director or officer against liability and reasonable
 expenses (including attorneys' fees) incurred by such person in the
 defense of any threatened, pending or completed civil, criminal,
 administrative or investigative action, suit or proceeding in which such
 person is made a party by reason of being or having been a director or
 officer of Registrant, unless liability was incurred because such person
 breached or failed to perform a duty owed to the Registrant which
 constituted (i) a willful failure to deal fairly with the Registrant or
 its shareholders in connection with a matter in which such person has a
 material conflict of interest; (ii) a violation of criminal law, unless
 such person had reasonable cause to believe his or her conduct was lawful
 or no reasonable cause to believe his or her conduct was unlawful; (iii) a
 transaction from which such person derived an improper personal profit; or
 (iv) willful misconduct.  The statute provides that indemnification
 pursuant to its provisions is not exclusive of other rights or
 indemnification to which a person may be entitled under the Registrant's
 articles of incorporation or bylaws, or any written agreement, vote of
 shareholders or disinterested directors, or otherwise.

     Section 180.0859 of the Wisconsin statutes provides that it is the
 public policy of the State of Wisconsin that such indemnification
 provisions apply, to the extent applicable to any other proceeding, to,
 among other things, the offer, sale or purchase of securities in any
 proceeding involving a state or federal statute.

     Article III, Section 14, of the Registrant's Bylaws essentially
 parallels the provisions of sections 180.0850 to 180.0859 of the Wisconsin
 statutes.  The Bylaws extend coverage to directors or officers serving in
 a fiduciary or administrative capacity with respect to a Registrant-
 sponsored employee benefit plan and also set forth procedures to be
 followed in obtaining indemnification.  Officers and directors of
 Registrant are also insured, subject to certain specified exclusions and
 deductible and maximum amounts, against loss from claims arising in
 connection with their acting in their respective offices, which include
 claims under the Securities Act of 1933, as amended.

 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;

               (ii) To reflect in the prospectus any facts or events
                    arising after the effective date of the Registration
                    Statement (or the most


                                -4-




                    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 Commission 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)(i) and (a)(ii) do not
               apply if the information required to be included in a post-
               effective amendment by those paragraphs is contained in the
               periodic reports filed by the Registrant pursuant to
               Section 13 or 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)  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.


                                -5-


     (h)  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.


                                -6-

                            SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the
 Registrant certifies that it has reasonable grounds to believe that it
 meets all of the requirements for filing on Form S-8 and has duly caused
 this Amendment No. 1 to this Registration Statement on Form S-8 to be
 signed on its behalf by the undersigned, thereunto duly authorized, in the
 City of Wausau, State of Wisconsin, on August 21, 1995.
