------------------------        -----------------        ----------
Customer                        Date                     Amount


The  undersigned  ("Customer", whether one or more) promises to pay to the order
of  M&I  Marshall & Ilsley Bank ("Lender") at 770 North Water Street, Milwaukee,
Wisconsin  53202,  the principal sum of $5,000,000.00 or, if less, the aggregate
unpaid principal amount of all loans made under this Note, plus interest, as set
forth  below.

Lender  will  disburse  loan  proceeds  to  Customer's  deposit  account  number
_______________________  or  by  other  means  acceptable  to  Lender.

Interest  is payable on JANUARY 31,2005, and on the last day of each consecutive
                        ---------------
month  thereafter  and  at  maturity.

Principal  is  payable  JULY  31,  2005.
                        ---------------

This  Note  bears  interest  on  the  unpaid  principal  balance before maturity
(whether  upon  demand, acceleration or otherwise) at the rates set forth on the
One  Month  Libor  Addendum  attached  hereto.

Interest is computed on the basis of a 360-day year on the actual number of days
principal  is unpaid. Unpaid principal and interest bear interest after maturity
(whether  by  acceleration  or  lapse  of  time) until paid at the prime rate of
interest  adopted  by  Lender  as its base rate for interest rate determinations
from  time  to  time  which  may or may not be the lowest rate charged by Lender
("Prime Rate") (with the rate changing as and when that Prime Rate changes) plus
3%.

If  any  payment  is  not  paid  when  due,  if a default occurs under any other
obligation  of  any  Customer  to Lender or if Lender deems itself insecure, the
unpaid  balance  shall,  at  the option of Lender, and without notice mature and
became  immediately  payable.  The unpaid balance shall automatically mature and
become  immediately  payable  in  the  event  any Customer, surety, or guarantor
becomes  the  subject  of  bankruptcy  or other insolvency proceedings. Lender's
receipt  of any payment on this Note after the occurrence of an event of default
shall  not  constitute  a  waiver of the default or Lender's rights and remedies
upon  such  default

The  acceptance  of  this  Note,  the making of any loan, or any other action of
Lender  does not constitute an obligation of commitment of Lender to make loans;
and  any  loans may be made solely in the discretion of Lender. This Note may be
prepaid  in  full  or  in  part  without  penalty.

Lender  is  authorized  to  automatically charge payments due under this Note to
account  number_______________  at  M&I Marshall & Ilsley Bank (See reverse side
regarding  Notice  of  Transfers  Varying  in  Amount.)

This  Note  includes  additional  provisions.

--------------------------------------------------------------------------------



                              ADDITIONAL PROVISIONS

This Note is secured by all existing and future security agreements, assignments
and  mortgages  between Lender and Customer, between Lender and any guarantor of
this Note, and between Lender and any other person providing collateral security
for  Customer's  obligations, and payment may be accelerated according to any of
them.  Unless  a  lien  would  be prohibited by law or would render a nontaxable
account  taxable,  Customer grants to Lender a security interest and lien in any
deposit  account  Customer  may at any time have with Lender. Lender may, at any
time  after  an  occurrence  of  an  event of default, without notice or demand,
setoff  against  any  deposit  balances or other money now or hereafter owed any
Customer  by  Lender  any  amount  unpaid  under  this  Note.

Lender  is authorized to make book entries evidencing loans and payments and the
aggregate  of  all  loans  as evidenced by those entries is presumptive evidence
that those amounts are outstanding and unpaid to Lender. Customer covenants that
all  loans  shall  be  used  solely  for  business  and  not  personal purposes.

Customer  agrees  to  pay  all costs of administration and collection before and
after  judgment,  including reasonable attorneys' fees (including those incurred
in  successful  defense or settlement of any counterclaim brought by Customer or
incident  to any action or proceeding involving Customer brought pursuant to the
United  States  Bankruptcy  Code),  provided,  however,  that  if Arizona law is
applicable  to  this  Agreement  and  if  the  Credit  Limit is $10,000 or less,
Customer  agrees  to pay court costs, expenses and reasonable attorneys' fees if
the  Loans under this Note are referred for collection to an attorney other than
a  salaried employee of Lender. Customer waives presentment, protest, demand and
notice  of  dishonor. Customer agrees to indemnify and hold harmless Lender, its
directors,  officers, employees and agents, from and against any and all claims,
damages,  judgments,  penalties,  and  expenses, including reasonable attorneys'
fees, arising directly or indirectly from credit extended under this Note or the
activities  of  Customer.  This  Indemnity  shall  survive payment of this Note.

Customer acknowledges that Lender has not made any representations or warranties
with  respect to, and that Lender does not assume any responsibility to Customer
for,  the  collectability  or  enforceability  of  this  Note  or  the financial
condition  of any Customer. Customer authorizes Lender to disclose financial and
other  information  about  Customer  to  others. Each Customer has independently
determined  the  collectability  and  enforceability  of  this  Note.

Without  affecting  the  liability of any Customer, surety, or guarantor, Lender
may,  without  notice, accept partial payments, release or impair any collateral
security  for  the  payment of this Note or agree not to sue any party liable on
it.  Without affecting the liability of any surety or guarantor, Lender may from
time  to  time,  without  notice,  renew  or  extend  the time for payment.  The
obligations  of  all  Customers  under  this  Note  are  joint  and  several.

To  the extent not prohibited by law, Customer consents that venue for any legal
proceeding relating to collection of this Note shall be, at Lender's option, the
county  in  which  Lender  has its principal office in this state, the county in
which  any  Customer resides or the county in which this Note was executed. This
Note  shall  be  construed  and enforced in accordance with the internal laws of
Wisconsin.

This  Note is intended by Customer and Lender as a final expression of this Note
and  as  a  complete  and  exclusive  statement  of  its  terms,  there being no
conditions to the enforceability of this Note. This Note may not be supplemented
or  modified  except  in  writing,  and  except  as set forth in One Month Libor
Addendum  attached  hereto.

                        PREAUTHORIZED TRANSFER DISCLOSURE

When Customer authorizes Lender to obtain payment of amounts becoming due Lender
by  initiating  charges  to  Customer's  account,  Customer  also  requests  and
authorizes remitting financial institution to alert and honor same and to charge
same  in  Customer's  account.  This  authorization  will remain in effect until
Customer  notifies  Lender and the remitting financial institution in writing to
terminate this authorization and Lender and remitting financial institution have
a  reasonable  time  to  act  on the termination. NOTICE OF TRANSFERS VARYING IN
AMOUNT: If Lender and remitting financial institution are not the same, Customer
is  an individual, the account was established primarily for personal, family or
household purposes and the regular payments may vary in amount, Customer has the
right  to  receive  a notice from Lender 10 days before each payment of how much
the  payment  will be; however, by signing this Note, Customer elects to receive
notice  only  when current payments would differ by more than 100% from previous
payment.



                            ONE MONTH LIBOR ADDENDUM
                           TO REVOLVING BUSINESS NOTE


This  note  bears interest on the unpaid principal balance before maturity at an
annual  rate  equal  to  the  ONE MONTH LIBOR RATE (as defined below) PLUS 2.00%
(percentage  points),  which rate will change as of the first day of each month.


"ONE  MONTH  LIBOR  RATE"  means the annual rate equal to the rate at which U.S.
dollar  deposits are offered on the first day of each calendar month on or about
9  a.m.,  Milwaukee,  Wisconsin  time  as  determined  by  the  British  Bankers
Association  (BBA LIBOR) and reported by a major news service selected by Lender
(such  as  Reuters,  Bloomberg  or  Moneyline  Telerate).


If  BBA  LIBOR-for the one month period is not provided or reported on the first
day  of  a month because, for example, it is a weekend or holiday or for another
reason, the One Month LIBOR Rate shall be established as of the preceding day on
which  a  BBA  LIBOR rate is provided for a one month period and reported by the
selected  news  service.
