PROMISE TO PAY.  STERION INCORPORATED (“Borrower”) promises to pay to Citizens Independent Bank (“Lender”), or order, in lawful money of the United States of America, the principal amount of One Million Five Hundred Thousand & 00/100 Dollars ($1,500,000.00), together with interest on the unpaid principal balance from November 26, 2003, until paid in full.

PAYMENT.  Subject to any payment changes resulting from changes in the Index, Borrower will pay this loan in 60 payments of $27,921.56 each payment.  Borrower’s first payment is due December 1, 2003, and all subsequent payments are due on the same day of each month after that.  Borrower’s first payment will be due on November 1, 2008, and will be for all principal and all accrued interest not yet paid.  Payments include principal and interest.  Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid interest; then to principal; then to any unpaid collection costs; and then to any late charges.  The annual interest rate for this Note is computed on a 365/360 basis; that is, by applying the ratio of the annual interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the ac tual number of days the principal balance is outstanding.  Borrower will pay Lender at Lender’s address shown above or at such other place as Lender may designate in writing.

VARIABLE INTEREST RATE.  The interest rate on this Note is subject to change from time to time based on changes in an independent index which is the Wall Street Journal Prime Rate as quoted in the Wall Street Journal (the “Index”).  The Index is not necessarily the lowest rate charged by Lender on its loans.  If the Index becomes unavailable during the term of this loan, Lender may designate a substitute index after notice to Borrower.  Lender will tell Borrower the current Index rate upon Borrower’s request.  The interest rate change will not occur more often than each day.  Borrower understands that Lender may make loans based on other rates as well.  The Index currently is 4.000% per annum.  The interest rate is to be applied to the unpaid principal balance of this Note will be at a rate of 0.500 percentage points over the Index, resulting in an in itial rate of 4.500% per annum.  NOTICE:  Under no circumstances will the interest rate on this Note be more than the maximum rate allowed by applicable law.  Whenever increases occur in the interest rate, Lender, at its option, may do one or more of the following: (A) increase Borrower’s payments to ensure Borrower’s loan will pay off by its original final maturity date, (B) increase Borrower’s payments to cover accruing interest, (C) increase the number of Borrower’s payments, and (D) continue Borrower’s payments at the same amount and increase Borrower’s final payment.

PREPAYMENT.  Borrower may pay without penalty all or a portion of the amount owed earlier than it is due.  Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower’s obligation to continue to make payments under the payment schedule.  Rather, early payments will reduce the principal balance due and may result in Borrower’s making fewer payments.  Borrower agrees not to send Lender payments marked “paid in full”, “without recourse”, or similar language.  If Borrower sends such a payment, Lender may accept it without losing any of Lender’s rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender.  All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes “payment in full&# 148; of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to:  Citizens Independent Bank, 5050 Excelsior Boulevard St. Louis Park, MN 55416.

LATE CHARGE.  If a payment is 20 days or more late, Borrower will be charged $50.00.

INTEREST AFTER DEFAULT.  Upon default, including failure to pay upon final maturity, the total sum due under this Note will bear interest from the date of acceleration or maturity at the variable interest rate on this Note.  The interest rate will not exceed the maximum rate permitted by applicable law.

Creditor or Forfeiture Proceedings.  Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Borrower or by any governmental agency against any collateral securing the loan.  This includes a garnishment of any of Borrower’s accounts, including deposit accounts, with Lender.  However, this Event of Default shall not apply if there is a good faith dispute by Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.
