percentages in aggregate principal amount of the 7% Senior Notes at the time
outstanding, on behalf of the Holders of all 7% Senior Notes, to waive
compliance by the Company and the Guarantor with certain provisions of the
Indenture and certain past Defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Senior Note shall be conclusive
and binding upon such Holder and upon all future Holders of this Senior Note and
of any 7% Senior Notes issued upon the registration of transfer thereof or in
exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Senior Note.

                  No reference herein to the Indenture and provision of this
Senior Note or of the Indenture shall alter or impair the obligation of the
Company and the Guarantor, which is absolute and unconditional, to pay the
principal of (and premium, if any) and interest on this Senior Note at the
times, place and rate, and in the coin or currency, herein prescribed.

                  As provided in the Indenture and subject to certain
limitations on transfer of this Senior Note by DTC or its nominee, the transfer
of this Senior Note is registrable by the Registrar, upon surrender of this
Senior Note for registration of transfer at the office or agency of the Company
or the Guarantor, as the case may be, in Milwaukee, Wisconsin and the Borough of
Manhattan, The City of New York, New York, duly endorsed by, or accompanied by
the written instrument of transfer attached hereto duly executed by the Holder
hereof or his attorney duly authorized in writing, and thereupon one or more new
7% Senior Notes, of authorized denominations and for the same aggregate
principal amount, shall be issued to the designated transferee or transferees.

                  The 7% Senior Notes are issuable only in fully registered form
without coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
the 7% Senior Notes are exchangeable for a like aggregate principal amount of 7%
Senior Notes of different authorized denomination, as requested by the Holder
surrendering the same.

                  No service charge shall be made for any such registration of
transfer or exchange of 7% Senior Notes, but the Company and the Guarantor may
require payment

of a sum sufficient to cover any tax or other governmental charge payable in
connection therewith.

Notes, upon written request and without charge, a copy of the Indenture.

                  FOR VALUE RECEIVED, the Guarantor, hereby unconditionally
guarantees to the Holder of the Security upon which this Guarantee is endorsed
the due and punctual payment of the principal, of premium, if any, or interest
on said Security, when and as the same shall be become due and payable, whether
at maturity, upon redemption or otherwise, according to the terms thereof and of
the Indenture referred to therein.

                  The Guarantor agrees to determine, at least one business day
prior to the date upon which a payment of principal, of premium, if any, or
interest on said Security is due and payable, whether the Company has available
the funds to make such payment as the same shall become due and payable. In case
of the failure of the Company punctually to pay any such principal, premium, if
any, or interest, the Guarantor hereby agrees to cause any such payment to be
made punctually when and as the same shall become due and payable, whether at
maturity, upon redemption or otherwise, and as if such payment were made by the
Company.

                  The Guarantor hereby agrees that its obligations hereunder
shall be unconditional, irrevocable and absolute, irrespective of the validity,
regularity or enforceability of said Security or said Indenture, the absence of
any action to enforce the same, any waiver or consent by the Holder of said
Security with respect to any provisions thereof, the recovery of any judgment
against the Company or any action to enforce the same or any other circumstance
which might otherwise constitute a legal or equitable discharge or defense of a

Guarantor pursuant to the provisions of this Guarantee; provided, however, that
the Guarantor shall not, without the consent of the Holders of all of the
Securities then outstanding, be entitled to enforce or to receive any payments
arising out of or based upon such right of subrogation until the principal of
and premium, if any, and interest on all Securities shall have been paid in full
or payment thereof shall have been provided for in accordance with said
Indenture.

                  Notwithstanding anything to the contrary contained herein, if

jurisdiction that such payment shall be avoided by a trustee in bankruptcy
(including any debtor-in-possession) as a preference under 11 U.S.C. Section 547
and such payment is paid by such Holder to such trustee in bankruptcy, then and
to the extent of such repayment the obligations of the Guarantor hereunder shall
remain in full force and effect.

                  This Guarantee shall not be valid or become obligatory for any
purpose with respect to a Security until a certificate of authentication on such
Security shall have been signed by the Trustee (or the authenticating agent).
