Initials

/s/ SCJ
--------- 12. GENERAL: My agent may do any act or thing that I could
do in my own proper person if personally present, including managing or selling
tangible assets, disclaiming a probate or nonprobate inheritance and providing
support for a minor child or dependent adult. The specifically enumerated powers
of the basic power of attorney for finances and property are not a limitation of
this intended broad general power except that my agent may not take any action
prohibited by law and my agent under this document may not:

          a. Make medical or health care decisions for me.

          b. Make, modify or revoke a will for me.

          c. Other than a burial trust agreement under section 445.125,
     Wisconsin Statutes, enter into a trust agreement on my behalf or amend or
     revoke a trust agreement, entered into by me.

          d. Change any beneficiary designation of any life insurance policy,
     qualified retirement plan, individual retirement account or payable on
     death account or the like whether directly or by canceling and replacing
     the policy or rollover to another plan or account.

          e. Forgive debts owed to me or disclaim or waive benefits payable to
     me, except a probate or nonprobate inheritance.

          f. Appoint a substitute or successor agent for me.

          g. Make gifts.

          . . .

     I agree that any third party who receives a copy of this document may act
under it. Revocation of this basic power of attorney is not effective as to a
third party until the third party learns of the revocation. I agree to reimburse
the third party for any loss resulting from claims that arise against the third
party because of reliance on this power of attorney.

     Signed this 22 day of April, 2003.
